Abstract
Objective Mucuna pruriens (MP) is a legume whose seeds contain levodopa (LD), which has potential therapeutic effects against Parkinson's disease (PD). However, further research is needed to thoroughly evaluate its efficacy and safety for treating this condition. In this study, we analyzed the pharmacokinetics of MP grown in Japan and investigated its mechanism of action in PD. Methods MP seeds ground after roasting (containing 4.02% LD per MP powder) were used as the reagent and compared with an equivalent LD/carbidopa (CD) preparation. This clinical trial was conducted using a crossover design among PD patients attending our institution. Each patient received a single dose of 100/10 mg LD/CD tablets and 11 g of MP reagent. Results Among the seven patients with PD, MP prolonged the ON time 2-fold compared to LD/CD. The LD concentrations after MP intake were higher than those after LD/CD intake, whereas dyskinesia did not increase. An analysis of the LD metabolites showed that the 3-O-methyl-dopa/LD metabolic ratio was significantly lower after MP ingestion than after LD/CD ingestion, indicating that MP has a catechol-O-methyl transferase inhibitory effect. Conclusions This is the first report of a pharmacokinetic analysis conducted on actual patients with PD showing that MP significantly prolongs the ON time. The advantages of MP as a treatment for PD have been confirmed: it is inexpensive, as effective as LD, works faster and longer than LD, and does not increase dyskinesia.

Abstract
Mucuna pruriens (MP) which is commonly known as "Velvet Bean" is an underutilized legume traditionally used to treat Parkinson's disease and male fertility issues. Extracts of MP have also been identified for their antidiabetic, antioxidant, and antineoplastic effects. Commonly, the antioxidant and anticancer properties of a drug are linked together as antioxidants scavenge free radicals and prevent the cellular DNA damage which could result in cancer development. In this investigation, comparative assessment of the anticancer and antioxidant potentials of methanolic seed extracts from two common varieties of MP, Mucuna pruriens var. pruriens (MPP) and Mucuna pruriens var. utilis (MPU) against human colorectal cancer adenocarcinoma cells COLO-205, was carried out. The highest antioxidant potential was recorded with MPP with an IC50 of 45.71 μg/ml. The in vitro antiproliferative effects of MPP and MPU on COLO-205 showed an IC50 of 131.1 μg/ml and 246.9 μg/ml respectively. Our results revealed intervention of the MPP and MPU extracts in growth kinetics of the COLO-205 cells in concomitance with apoptosis induction up to 8.73- and 5.58-folds respectively. The AO/EtBr dual staining and the flow cytometry results also confirmed the better apoptotic efficacy of MPP over MPU. MPP at a concentration of 160 μg/ml exhibited highest apoptosis and cell cycle arrest. Furthermore, effect of the seed extracts on p53 expression was investigated by quantitative RT-PCR and a maximum upregulation of 1.12-fold was recorded with MPP.

Abstract
Mucuna pruriens (MP) is leguminous plant which contains 5% of L-3,4-dihydroxyphenylalanine (levodopa) in its seeds. It may have a potential to be used as an alternative therapy for Parkinson's disease (PD). Meanwhile, there is a concern in terms of public health that MP products can be overused by patients with PD. As an entry for patients with PD to acquire MP products in Japan, they are often purchased via internet auctions or free markets. MP products are not reagrded as 'pharmatheutical' by Japanese law as long as the specific legal requirements on advertisements are met, so that the MP products can be advertised or sold without any permission from the authorities. In this study, we aimed to conduct internet survey as to the complianse status of these legal requirements. Several major internet auction or free market websites in Japan were surveyed in May-June 2023 by the authors, and 1157 MP product pages were examined. We found approximately 30-40% of the MP products were suspected to have potential legal risks in terms of their advertisements in their website descriptions, such as claiming pharmatheutical efficacy or describing pharmatheutical-like dosages. In addition, approximately 30-40% of the MP products also did not refer to cautions not to take MP products excessively because of the levodopa ingredients. Current study suggested the need of careful description of the MP products in the auction or free market websites for the MP products exhibitors or sellers, in order to fullfill legal requirements as well as to prevent MP abuse.

Abstract
There is growing interest in the use of natural products for the treatment of Parkinson's disease (PD). Mucuna pruriens has been used in the treatment of humans with PD. The goal of this study was to determine if daily oral treatment with an extract of Mucuna pruriens, starting after the MPTP-induced loss of nigrostriatal dopamine in male mice, would result in recovery/restoration of motor function, tyrosine hydroxylase (TH) protein expression in the nigrostriatal pathway, or glutamate biomarkers in both the striatum and motor cortex. Following MPTP administration, resulting in an 80 % loss of striatal TH, treatment with Mucuna pruriens failed to rescue either striatal TH or the dopamine transporter back to the control levels, but there was restoration of gait/motor function. There was an MPTP-induced loss of TH-labeled neurons in the substantia nigra pars compacta and in the number of striatal dendritic spines, both of which failed to be recovered following treatment with Mucuna pruriens. This Mucuna pruriens-induced locomotor recovery following MPTP was associated with restoration of two striatal glutamate transporter proteins, GLAST (EAAT1) and EAAC1 (EAAT3), and the vesicular glutamate transporter 2 (Vglut2) within the motor cortex. Post-MPTP treatment with Mucuna pruriens, results in locomotor improvement that is associated with recovery of striatal and motor cortex glutamate transporters but is independent of nigrostriatal TH restoration.

Abstract
Mucuna pruriens seed being an underutilized legume with antinutrients was processed to reduce antinutrients and improve nutritional quality. The seeds were cleaned, washed and subjected to single treatments of soaking (24 h, 48 h, 72 h), cooking (20 min, 40 min, 60 min, 80 min), roasting (10 min, 15 min, 20 min), germination (24 h, 48 h, 72 h) and fermentation (24 h, 48 h, 72 h). Combined treatments: soaking (72 h) + cooking (60 min); germination (48 h) + roasting (15 min); germination (48 h) + cooking (60 min); fermentation (72 h) + roasting (15 min) were also separately carried out. Proximate composition and antinutrients were evaluated. Crude protein ranged from 25.34 to 29.50%, ash 3.02-3.82% and crude fibre 0.70-4.69. Crude protein was increased by single and double treatments while ash content was increased by only single treatments. All the treatments reduced the crude fibre. For single and double treatments, phenol, L-3,4-dihydroxyphenylalanine and trypsin inhibitor were in the range of 0.69-3.49%, 0.01-6.83% and 0.00-12.58 TIU/mg protein respectively. This research indicated that the use of up to 72 h soaking, 80 min cooking, 20 min roasting, 72 h germination or 72 h fermentation (Rhizopus oligosporus) is not adequate to reduce phenol and L-3,4-dihydroxyphenylalanine in Mucuna pruriens seed flour to below the recommended safe limits of 0.003% and 0.1% respectively. The double treatment of 72 h fermentation +15 m roasting was the only treatment that reduced L-3,4-dihydroxyphenylalanine to safe limit of 0.01%.

Abstract
Mucuna pruriens Linn. (M. pruriens), a leguminous plant, was used extensively in Ayurveda, to treat male-related infertility. Previous studies have demonstrated antioxidant, androgenic, aphrodisiac, and spermatogenic properties of M. pruriens seed extract. Surprisingly, the biological activities of M. pruriens on aging-induced pathological changes in the testis microenvironment have never been explored and the present study was focused on the testing therapeutic efficacy of M. pruriens on aged rat testis. Male Wistar albino rats were grouped as; adult (3 months), aged (24 months), aged + M. pruriens and adult + M. pruriens (N = 6/group). The extract was administrated at a dose of 200 mg/kg body weight (dosage determined in our previous study) daily by gavage for 60 days. The total and free testosterone, FSH and LH levels were considerably increased in aged + M. pruriens. The diameter & volume of the seminiferous tubules, the height & volume of the epithelium, and the number of Leydig cells number were significantly decreased in aged rat testis, concomitantly connective tissue proportion was increased compared to adult rats. The seminiferous epithelium indicates significant rejuvenation or restoration of spermatogenic cells in aged + M. pruriens rat testis. The highlighting observations in aged + M. pruriens was increased in the following parameters i.e., tubular diameter (25%), number of tubules (35%), epithelial height (25%) & volume (20%), and number of Leydig cells (35%) when compared to untreated aged rat testis. The TNFα, NF-κB, cytochrome c, Caspase-9, Caspase-3, Bcl-2, Bax, PARP iNOS, and inflammatory and apoptotic factors were downregulated in aged + M. pruriens. M. pruriens was able to restore spermatogenesis and enhance the activity of Sertoli cells and Leydig cells and improve the pituitary-gonadal axis in aged rat testis and observations indicate the therapeutic activity of M. pruriens in aged rat testis.

Abstract
Background and Aim A significant cause of arsenic poisoning is polluted groundwater. Arsenic poisoning results in the suppression of spermatogenesis and the liver and kidneys are vulnerable to the toxic effects as well. Mucuna pruriens has been identified to have fertility-enhancing and anti-lipid peroxidation properties. Based on these properties of M. pruriens, this study aimed to investigate the efficacy of M. pruriens seed extract in reducing sodium arsenite-induced testicular impairment and hepato-renal histopathology in rats. Materials and Methods The study was divided into two groups; short-term (45 days) and long-term (90 days) treatment groups and each group was divided into nine subgroups. Subgroups 1 and 2 served as normal and N-acetyl cysteine (NAC) controls, respectively. Subgroups 3-9 received sodium arsenite in the drinking water (50 mg/L). Subgroup-4 received NAC (210 mg/kg body weight [BW]) orally once daily. Subgroups 5-7 received aqueous seed extract of M. pruriens (350, 530, and 700 mg/kg BW, respectively) orally once daily. Subgroups 8 and 9 received a combination of NAC and aqueous seed extract (350 and 530 mg/kg BW, respectively) orally once daily. Following the treatment, animals were sacrificed and sperm parameters and DNA damage were evaluated. Testis, liver, and kidneys were analyzed for histopathology. Results Sodium arsenite-induced a significant reduction in sperm parameters and increase in the abnormal architecture of spermatozoa. Histology revealed tissue necrosis. The M. pruriens seed extract ameliorated the damaging effects of sodium arsenite with respect to tissue architecture and sperm parameters when coadministered. Conclusion Mucuna pruriens has beneficial effects against the deleterious effects of sodium arsenite on various tissues. Thus, M. pruriens (530 and 700 mg/kg BW) supplementation would reduce the adverse changes observed with sodium arsenite exposure.

Abstract
Present study aimed to assess effect of pre-treatment with Mucuna pruriens seed extract and its bioactive molecule(s) on NMDAR and Tau protein gene expression in cerebral ischemic rodent model. Methanol extract of M. pruriens seeds was characterized by HPLC, and β-sitosterol was isolated by flash chromatography. In vivo studies to observe the effect of pre-treatment (28 days) with methanol extract of M. pruriens seed and β-sitosterol on the unilateral cerebral ischemic rat model. Cerebral ischemia induced by left common carotid artery occlusion (LCCAO) for 75 min (on day 29) followed by reperfusion for 12 h. Rats (n = 48) divided into four groups. GroupI (control,Untreated + LCCAO)-No pre-treatment + cerebral ischemia; GroupII(β-sitosterol + Sham)-pre-treatment with β-sitosterol, 10 mg/kg/day + sham-operated; GroupIII(β-sitosterol + LCCAO)-pre-treatment with β-sitosterol, 10 mg/kg/day + cerebral ischemia; GroupIV(methanol extract + LCCAO)-pre-treatment with methanol extract of M. pruriens seeds, 50 mg/kg/day + cerebral ischemia. Neurological deficit score was assessed just before sacrifice. Experimental animals were sacrificed after 12 h reperfusion. Brain histopathology was performed. Gene expression of NMDAR and Tau protein of left cerebral hemisphere (occluded side) was performed by RT-PCR. Results revealed that the neurological deficit score was lower in groups III and IV compared to group I. NMDAR and tau protein mRNA expression in left cerebral hemisphere were upregulated in Group I, downregulated in groups III and IV. Histopathology of left cerebral hemisphere (occluded side) in Group I showed features of ischemic brain damage. Groups III and IV, left cerebral hemisphere showed less ischemic damage compared GroupI. Right cerebral hemisphere showed no areas of ischemia-induced brain changes. Pre-treatment with β-sitosterol and methanol extract of M. pruriens seeds may reduce ischemic brain injury following unilateral common carotid artery occlusion in rats.

Abstract
In this study, Mucuna pruriens extracts were used to verify their application as a natural-based raw material with anti-inflammatory function. A nitric oxide inhibition activity assay showed that M. pruriens extracted with hot water (MW), M. pruriens extracted with 70% ethanol (ME), and M. pruriens extracted with 70% acetone (MA) presented NO inhibition activity; among them, MW and ME demonstrated the best activity and were selected for Western blot analysis. After identifying the expression patterns of inflammation-related proteins, such as inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), c-jun N-terminal kinase (JNK), extracellular signal-regulated kinase (ERK), and nuclear factor kappa-light-chain-enhancer of activated B cell (NF-κB), through Western blots, both MW and ME showed inhibition patterns. As a result of analyzing L-DOPA contained in M. pruriens through ultra-performance liquid chromatography (UPLC), high L-DOPA content was detected in MW, ME, and MA. Therefore, it can be concluded that M. pruriens extracts have the potential for use as an anti-inflammatory material.

Abstract
A tetrahydroisoquinoline identified in Mucuna pruriens ((1R,3S)-6,7-dihydroxy-1-methyl-1,2,3,4-tetrahydroisoquinoline-1,3-dicarboxylic acid, compound 4) was synthesized and assessed for its in vitro pharmacological profile and in vivo effects in two animal models of Parkinson's disease. Compound 4 inhibits catechol-O-methyltransferase (COMT) with no affinity for the dopaminergic receptors or the dopamine transporter. It restores dopamine-mediated motor behavior when it is co-administered with L-DOPA to C. elegans worms with 1-methyl-4-phenylpyridinium-damaged dopaminergic neurons. In a 6-hydroxydopamine rat model of Parkinson's disease, its co-administration at 30 mg/kg with L-DOPA enhances the effect of L-DOPA with an intensity similar to that of tolcapone 1 at 30 mg/kg but for a shorter duration. The effect is not dose-dependent. Compound 4 seems not to cross the blood-brain barrier and thus acts as a peripheral COMT inhibitor. COMT inhibition by compound 4 further validates the traditional use of M. pruriens for the treatment of Parkinson's disease, and compound 4 can thus be considered as a promising drug candidate for the development of safe, peripheral COMT inhibitors.

Abstract
Nutraceuticals have received increased attention in sustainable aquaculture. Consequently, the present study aimed to evaluate the dietary effects of Mucuna pruriens (MP) seed extract on growth performance, immune status, hepatic function, biochemical profiles, gonadal histology, and expression of immune-related genes in mono-sex Nile tilapia (Oreochromis niloticus). Fish were allocated into four groups and received MP at rates of 0 (control), 2, 4, and 6 g/kg diet, respectively, for 90 days. The results revealed that MP significantly (P<0.05) modulated growth performance (specific growth rate, final length, and length gain rate, body mass gain, and feed conversion ratio), lysozyme activity, and liver enzymes (AST, ALT). However, a non-significant effect on nitric oxide (NO) or immunoglobulin M (IgM) levels was detected, whereas the dietary inclusion of MP had a hypoglycemic effect. In terms of plasma globulin, albumin, globulin/albumin ratio, and cortisol, the MP receiving groups showed insignificant difference (P<0.05) when compared to controls, except for the 2 g MP-supplemented group. The lower inclusion concentration of MP (2 g/kg diet) demonstrated the best result (P < 0.05) for gonadosomatic index (GSI) and plasma testosterone level that was consistent with the histological findings reflecting an improvement in the testicular development compared with the control group. Expressions of complement component (C5) and interleukin 1-β (IL-1β) genes were significantly up-regulated in MP receiving groups. In conclusion, M. pruriens can be used as a safe natural economic feed additive and a low inclusion level of 2 g/kg diet is recommended to improve growth, enhance immunity, maintain liver functioning, improve testicular development, and to modulate immune-related genes in the mono-sex O. niloticus.

Abstract
The liver and kidneys are the vital organs of the body and perform important life-sustaining functions in the body. Synthetic drugs used in the treatment of liver and kidney diseases are sometimes inadequate and can lead to serious side effects. Medicinal herbs and plants were used to combat diseases for a long time and combination therapy is preferred over single plant therapy. In the current study, the Asparagus racemosus, Mucuna pruriens, Anacyclus pyrethrum, and Tribulus terrestris polyherbal preparation (PHP) was selected to evaluate its hepatoprotective, antioxidant, and anti-nephrotoxic potential. The methanolic extract of PHP was prepared following standard protocols. Fifty-six albino rats were divided into 7 groups (n = 8). The negative control (NC) having the healthy rats and the remaining 6 groups were induced liver toxicity by intraperitoneally injecting 0.5 mL/kg of 50% CCl4 in olive oil. Group 2 was positive control and group 3 and 4 received silymarin standard drug at the dose of 100 and 200 mg/kg body weight. Groups 5, 6, and 7 (PHP-1, PHP-2, PHP-3) were the liver-damaged rats receiving the PHP at a dose of 50, 100, and 150 mg/kg body weight. Blood samples were collected at 21 of the trial, to evaluate oxidative stress, hepatoprotective and anti-nephrotoxic potential. Results of liver function tests revealed significant (P < .05) hepatoprotective activities of PHP after intoxication with CCl4 of albino rats as compared to standard groups. Moreover, results of renal functions also showed that PHP has a significant (P < .05) restoring the capacity of blood urea, creatinine, and uric acid in intoxicated rats as compared with the control group. The PHP also reduced the oxidative stress in the treatment groups by increasing the total antioxidant capacity and reducing the total oxidative status. It can be concluded that selected medicinal plants have a potential role in the management of liver and kidney disorders. So, by running the clinical trial on a large scale and by isolating the phytochemical constituents responsible for hepatoprotective and nephroprotective activities, locally prepared drugs could be developed to manage liver and renal disorders.

Abstract
The medicinal plant Mucuna pruriens (Fabaceae) is widely known for its anti-oxidative and anti-inflammatory properties. It is a well-established drug in Ayurveda and has been widely used for the treatment of neurological disorders and male infertility for ages. The seeds of the plant have potent medicinal value and its extract has been tested in different models of neurodegenerative diseases, especially Parkinson's disease (PD). Apart from PD, Mucuna pruriens is now being studied in models of other nervous systems disorders such as Alzheimer's disease (AD), Amyotrophic lateral sclerosis (ALS) and stroke because of its neuroprotective importance. This review briefly discusses the pathogenesis of PD, AD, ALS and stroke. It aims to summarize the medicinal importance of Mucuna pruriens in treatment of these diseases, and put forward the potential targets where Mucuna pruriens can act for therapeutic interventions. In this review, the effect of Mucuna pruriens on ameliorating the neurodegeneration evident in PD, AD, ALS and stroke is briefly discussed. The potential targets for neuroprotection by the plant are delineated, which can be studied further to validate the hypothesis regarding the use of Mucuna pruriens for the treatment of these diseases.

Abstract
Objective Mucuna pruriens Linn., a leguminous plant, is identified as a herbal medicine for improving fertility-related disorders in the alternative and complementary systems of medicine. The study was focused on evaluating the therapeutic potential of M. pruriens on testis and sperm parameters in a high-fat-induced hypercholesterolemia model. Materials and Methods Male rats were divided as normal-control rats (NCR); normal-control rats + M.pruriens (200 mg/kg b.w. of ethanolic extract of M. pruriens seed) treated (NCRD); hypercholesterolemic rats (HCR) and hypercholesterolemic rats + M. pruriens (HCRD). Groups were further divided into three post-exposure periods (subgroups) of 9, 18, and 36 days, and the progressive changes in testis histology and sperm were analyzed. Results The study showed a significant impairment in testicular histoarchitecture, depletion of antioxidant enzyme levels, increased oxidative stress and lipid peroxidation in the HCR group. The study indicated severe structural and functional damage in sperm parameters and diminished chromatin integrity in the HCR group. In the HCR rats, the follicular stimulating hormone (FSH) and luteinizing hormone (LH) and testosterone were significantly reduced. There was a significant improvement in sperm parameters and testis histology in the HCRD group. Conclusion The study reveals the potential efficacy of M. pruriens to improve spermatogenesis, sperm parameters and hormone levels in hypercholesterolemic rats.

Abstract
A Bowman-Birk protease, i.e., Mucuna pruriens trypsin inhibitor (MPTI), was purified from the seeds by 55.702-fold and revealed a single trypsin inhibitor on a zymogram with a specific activity of 202.31 TIU/mg of protein. On sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) under non-reducing conditions, the protease trypsin inhibitor fraction [i.e., trypsin inhibitor non-reducing (TINR)] exhibited molecular weights of 74 and 37 kDa, and under reducing conditions [i.e., trypsin inhibitor reducing (TIR)], 37 and 18 kDa. TINR-37 revealed protease inhibitor activity on native PAGE and 37 and 18 kDa protein bands on SDS-PAGE. TINR-74 showed peaks corresponding to 18.695, 37.39, 56.085, and 74.78 kDa on ultra-performance liquid chromatography (UPLC) coupled with electrospray ionization/quadrupole time-of-flight-mass spectrometry (ESI/QTOF-MS). Similarly, TINR-37 displayed 18.695 and 37.39 kDa peaks. Furthermore, TIR-37 and TIR-18 exhibited peaks corresponding to 37.39 and 18.695 kDa. Multiple peaks observed by the UPLC-ESI/QTOF analysis revealed the multimeric association, confirming the characteristic and functional features of Bowman-Birk inhibitors (BBIs). The multimeric association helps to achieve more stability, thus enhancing their functional efficiency. MPTI was found to be a competitive inhibitor which again suggested that it belongs to the BBI family of inhibitors, displayed an inhibitor constant of 1.3 × 10-6 M, and further demonstrates potent anti-inflammatory activity. The study provided a comprehensive basis for the identification of multimeric associates and their therapeutic potential, which could elaborate the stability and functional efficiency of the MPTI in the native state from M. pruriens.

Abstract
Background Mucuna pruriens (L.) has been used for the treatment of several ailments in folkloric medicine. The present study therefore investigates the hepatoprotective and nephroprotective potentials of its leaves extract with a view to providing a potent alternative in the management of liver and kidney diseases. Methodology Forty male albino rats were randomly placed into eight groups comprising five animals each. Animals in group I were administered with the distilled water, while groups II and VI were exposed to CCl4 and rifampicin respectively. Animals in groups III and IV were initially exposed CCl4 and treated with 50 and 100 mg/kg bw M. pruriens respectively. Similarly, groups VII and VIII animals were exposed to rifampicin and treated with 50 and 100 mg/kg bw M. pruriens respectively. Animals in group V were treated with 100 mg/kg bw silymarin by oral gavage after an initial exposure to CCl4. Selected biomarkers of liver and kidney damage were determined in the serum and organs homogenate. Liver and kidney slices of experimental animals were also stained for histopathological examination. Results Exposure to CCl4 and rifampicin respectively resulted in marked distortion in lipid profile, inhibition of antioxidant enzymes and a surge in ALT, AST, ALP, urea, uric acid, bilirubin and creatine kinase. Treatment with M. pruriens extract reversed all deranged biochemical and histopathological parameters in a dose-dependent manner. Conclusion Extract of M. pruriens leaves restored deranged biochemical and histopathological parameters in the liver and kidney with similar potency to silymarin. Hence, leaf extract of M. pruriens is a potential hepatoprotective and nephroprotective agent that can be exploited in the management of liver and kidney diseases.

Abstract
Mucuna pruriens is traditional medicinal plant originated in South Africa. We characterize the complete plastid genome of M. pruriens, which is a circular-mapping molecule 152,119 bp in length. The genome has a large single-copy region (LSC) of 78,258 bp and a small single-copy region (SSC) of 18,735 bp, respectively. Additionally, the overall GC content of the chloroplast genome was 35.37%. The genome contains 138 genes, including 96 protein-coding, 38 tRNA, and four rRNA genes. The gene content and structure are conserved compared to other species in the genus Glycine. The chloroplast genome and existing data were used to infer its phylogenetic position. The results showed that M. pruriens clustered together with Glycine max and G. soja. These findings provide potential genetic markers that can aid in understanding the genetic diversity of M. pruriens.

Abstract
BACKGROUND The World Health Organization included snakebite envenomation among Neglected Tropical Diseases in 2017. The importance of natural products from plants is enormous, given that most prescribed drugs originate from plants. Among this is Mucuna pruriens and Mimosa pudica, with many registered patents asserting their health benefits. OBJECTIVE This study investigated the in vitro neutralizing effects of Mucuna pruriens seed and Mimosa pudica root extracts on venoms of Naja nigricollis and Bitis arietans. METHODS In mice, the LD50 and phytochemical analysis of M. pruriens and M. pudica plant extracts were carried out prior to the evaluation of their haemolytic and fibrinolytic effect. Their effects on the activities of phospholipase A2 (PLA2) were also assessed. RESULTS At a concentration of 50 mg/ml, both plant extracts were found to neutralize the fibrinolytic activity of N. nigricollis, but 400 mg/ml was required to neutralize the fibrinolytic activity of B. arietans. In haemolytic studies, 50 mg/ml concentration of M. pruriens extract suppressed haemolysis caused by N. nigricollis venom by 70% but at the same concentration, M. pudica extract reduced haemolysis by 49.4%. M. pruriens, at 50 mg/ml concentration, only inhibited phospholipase A2 activity by 7.7% but higher concentrations up to 400mg/ml had no effect against the venom of N. nigricollis; at 200 mg/ml. M. pudica extract inhibited PLA2 activity by 23%. CONCLUSION The results suggest that M. pruriens and M. pudica may be considered as promising antivenom agents for people living in a snake-bite prone environment.

Abstract
Mucuna pruriens (Mp) is an annual and perennial legume which belongs to the family Fabaceae having different types of therapeutic activity. Anti-oxidative, anti-inflammatory, anti-epileptic, anti-microbial, etc. are the example of some most common activities of Mp. It is widely utilized as a potent aphrodisiac. The anti-Parkinsonian activity of Mp was explored since the nineteenth century. The neuroprotective activity of Mp was shown by several researchers. Levodopa (L-DOPA) is the important constituents responsible for the anti-Parkinsonian activity of Mp. Apart from L-DOPA, several other important bioactive components like Ursolic acid (UA) and Betulinic acid (BA) also exhibit a similar neuroprotective activity. Parkinson's disease (PD) is mainly sporadic. A very small proportion shows the genetic nature of PD. The anti-Parkinsonian activity of Mp was explored in different toxin-induced PD models as like MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine), Rotenone, Paraquat, 6-hydroxydopamine (6-OHDA) as suggested by several pieces of literature. Various parts of Mp's like seed, leaf, and stem exhibit potent neuroprotective attributes. Among different parts, seeds are widely utilized as anti-PD agents because of the higher percentage of L-DOPA. Besides anti-PD activity, Mp's neuroprotective potential was also explored in the ischemic model of stroke that also shows positive results. Recently, several clinical trials have been performed on the anti-PD activity of Mp on PD patients that show convincing results. Although, a small population-based study needs to be further validated in the broader population. Apart from anti-PD activity, Mp also shows its therapeutic activity in some other diseases like cancer, diabetes, skin infection, anemia, antihypertensive, etc. that are summarized in Table 1. In this review, we have discussed the anti-PD potential of Mp in the sporadic and genetic model along with some clinical trials that have performed on PD patients. Some other activity of Mp is also summarized in this review. There is a strong need to test the efficacy of Mp in some other neurodegenerative diseases along with PD. Following this, this review emphasizes the role of Mp in PD systematically through literature analysis available to date. [Table: see text].

Abstract
OBJECTIVE To study the effect of ethanolic seed extract of Mucuna pruriens on damaged dorsal nerve of the penis (DNP) in aged rat in relation to penile erection. METHODS The rats were divided into four groups Young (3 months), Aged (24 - 28 months), Aged + M. pruriens, and Young + M. pruriens (200 mg/kg b.w/60 days) and were subjected to the hypophysial - gonadal axis, nerve conduction velocity (NCV), and penile reflex. DNP sections were stained with nitric oxide synthase (nNOS), nicotinamide adenine dinucleotide phosphate (NaDPH) diaphorase, androgen receptor (AR), and osmium tetroxide. Terminal deoxynucleotidyl transferase (TdT) dUTP Nick-End Labeling (TUNEL) staining, electron microscopy(EM) and histometric analyses were done. RESULTS Significant disturbance in hypophysial - gonadal axis was noted in aged rat. With reduced number of myelinated fibers, diameter, vacuolization, indentation of the myelin sheath, and degeneration. nNOS and its cofactor (NaDPH diaphorase) were reduced in aged rat DNP. NCV was slow in aged rats and concomitant poor penile reflex was also noted. AR showed reduced expression in aged rat DNP when compared to young and control groups. TUNEL positive cells were increased in aged rat DNP. These pathological changes were remarkably reduced or recovered in M. pruriens treated aged rats. CONCLUSIONS The results indicate a multi-factorial therapeutic activity in penile innervations towards sustaining the penile erection in the presence of the extract in aged rats and justifying the claim of traditional usage.

Abstract
Sickle cell disease is a group of diseases inherited through the gene and it affects the haemoglobin in the red blood cell. This study investigated the methanol seed extract of Buchholzia coriacea for possible in vitro anti-sickling effects and also determined the effect of Mucuna pruriens seed extract on the solubility and oxygen-binding rate of sickle cell haemoglobin. Sickle cell blood was collected from sickle cell disease patients with subsequent addition of 2% sodium metabisulphite to cause more sickling. Varying concentrations of the seed extracts (50%, 25%, 12.5% and 6.25%) were added to the pre-treated blood for these in vitro assays. The results showed that the extract of Buchholzia coriacea significantly (P < 0.05) inhibited sickling at all concentrations with the highest percentage inhibition of 73.3 ± 5.8, reversed sickled erythrocytes at all concentrations with the highest percentage reversal of 83.3 ± 5.8 and significantly (P < 0.05) inhibited polymerisation at all concentrations used in comparison to the parallel control. The extract of Mucuna pruriens seed significantly (P < 0.05) increased the solubility of sickle haemoglobin at 50%, 25%, 12.5% and 6.25% concentrations, increased Fe2+/Fe3+ ratio from 1.7 (control) to 12.2 (50% concentration) and reduced osmotic fragility (at 12.5% and 6.25% concentrations) when compared with parallel control. The results indicate the feasibility of the seed extracts as promising agents in the management of sickle cell disease.

Abstract
Peptidase inhibitors (PIs) are plant proteins that are found to be effective against various digestive peptidases of insects. The present study isolated and characterized a trypsin inhibitor from mature dry seeds of Mucuna pruriens and investigated its effect against Bactrocera cucurbitae larvae, a major pest of cucurbitaceae crops, for its inhibitory activity. The purified trypsin inhibitor from M. pruriens seeds gave a molecular weight of ~11 kDa on SDS-PAGE. M. pruriens trypsin inhibitor (MPTI) exhibited inhibitory effect on growth of melon fruit fly larvae (64-72 h old) as it resulted in prolongation of larval, pupal and total development period. There was a significant increase in larval mortality with increase in concentration of MPTI. Nutritional indices decreased significantly at all the concentrations of MPTI. Quantitative RT- PCR revealed that the mRNA expression level of trypsin and chymotrypsin genes was reduced while that of GST, esterases, AP, SOD and catalase were enhanced. It can therefore be inferred that MPTI can serve as a promising agent for biocontrol that can reduce the problems caused by fruit fly and other similar catastrophic pests. This study provides the fundamental information for future successful strategies for pest management.

Abstract
This study aimed at assessing the biological activities of Mucuna pruriens seeds using cytotoxicity, phytochemical, antiparasitic screening, and antioxidant assays. Mature fruits of M. pruriens were harvested from Fort Hare University's Research Farm located in Alice, South Africa. The collected seeds were pulverized in a standard process and taken to the laboratory for crude extraction and further treatments. Cytotoxic, antimalarial, and trypanocidal effects of crude extracts obtained from ethanol and water were tested, while the total phenolic, proanthocyanidin, and flavonoid contents of the aqueous extracts as well as their pharmacological activities were determined in vitro using 2,2-diphenyl-1-picrylhydrazyl ethanol (DPPH), ferric reducing antioxidant power (FRAP), and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) assays. Although the extracts showed mild antiparasitic (antiplasmodial and trypanocidal) effects, results from the cytotoxic experiment revealed that M. pruriens is not toxic to human cervix adenocarcinoma (HeLa) cells when tested using 50 µg/mL of extracts. It was observed that the seeds were remarkably rich in phenol (3730.1 ± 15.52 mg gallic acid equivalent (GAE)/g) compared to flavonoids (63.03 ± 1.95 mg quercetin equivalent (QE)/g) and proanthocyanidin (18.92 ± 1.09 mg catechin equivalent (CE)/g). Also, the antioxidant activities of the extracts were comparable to those of the standard antioxidant drugs (rutin and gallic acid) used, in a concentration-dependent manner. There was a direct relationship between phenolic acid content and antioxidant effects. It is therefore suggested that M. pruriens seeds be incorporated into human diets as a supplement to promote healthy living. Pharmaceutical industries with a particular interest in natural phenolic acids should consider using seeds of M. pruriens as pharmaceutical precursors.

Abstract
BACKGROUND AND AIM Intoxication of arsenic in rats is known to result in neurological effects as well as liver and kidney dysfunction. Mucuna pruriens has been identified for its medicinal properties. The aim of the study was to investigate the protective effect of aqueous seed extract of M. pruriens on sodium arsenite-induced memory impairment, liver, and kidney functions in rats. MATERIALS AND METHODS The experiment was divided into short-term treatment (45 days) and long-term treatment (90 days), with each group divided into nine sub-groups consisting of six animals each. Sub-groups 1 and 2 served as normal, and N-acetylcysteine (NAC) controls, respectively. Sub-groups 3-9 received sodium arsenite in drinking water (50 mg/L). In addition, sub-group 4 received NAC (210 mg/kg b.wt) orally once daily, sub-groups 5-7 received aqueous seed extract of M. pruriens (350 mg/kg b.wt, 530 mg/kg b.wt, and 700 mg/kg b.wt) orally once daily and sub-groups 8 and 9 received a combination of NAC and aqueous seed extract of M. pruriens (350 mg/kg b.wt and 530 mg/kg b.wt) orally once daily. Following the treatment, the blood was drawn retro-orbitally to assess the liver (serum alanine transaminase [ALT], serum aspartate transaminase, and serum alkaline phosphatase) and kidney (serum urea and serum creatinine) functions. Learning and memory were assessed by passive avoidance test. Animals were sacrificed by an overdose of ketamine, and their Nissl stained hippocampal sections were analyzed for alterations in neural cell numbers in CA1 and CA3 regions. RESULTS In the short-term treatment, groups administered with M. pruriens 530 mg/kg b.wt alone and combination of NAC + M. pruriens 350 mg/kg b.wt exhibited a significant improvement in memory retention, less severe neurodegeneration, and decrease in serum ALT levels. In long-term treatment, groups administered with M. pruriens 700 mg/kg b.wt alone and combination of NAC+M. pruriens 350 mg/kg b.wt, respectively, showed better memory retention, decreased neural deficits, and reduced levels of kidney and liver enzymes. CONCLUSION The seed extract of M. pruriens showed significant enhancement in memory and learning. The number of surviving neurons in the CA1 and CA3 regions also increased on treatment with M. pruriens. Serum ALT, serum urea, and serum creatinine levels showed significant improvement on long-term treatment with M. pruriens.

Abstract
Mucuna pruriens belongs to the Fabaceae family and is ordinarily known as velvet bean, in English cowitch and Hindi Kawaanch. The restorative quality of this bean makes it an excellent component in pharmaceutical and therapeutic applications. Apart from high protein and starch content, these beans contain (l-Dopa) 3, 4-dihydroxy-l-phenylalanine, which exhibits several medicinal properties. However, it is poisonous when ingested by ruminants. The obstruction to the advancement of Mucuna as nutrition or food is the nearness of antinutrients, which are high as opposed to other uncommon vegetables. Also, this legume is considered as a future restorative herb because of its anticholesterolemic, anti-Parkinson, antioxidant, antidiabetic, sexual enhancing, anti-inflammatory, antimicrobial, and antivenom activities. It also exhibits anticancer activities, but very few studies have been done. The seeds of Mucuna pruriens also contain a vast range of phytochemical constituents such as alkaloids, glycosides, saponins, reducing sugars, and tannins, which provide an avenue to explore it for wider applications. This review sheds light on the possible mechanism of action of Mucuna pruriens on some diseases (hypoglycemia, Parkinson's disease, microbial diseases and tumor). and also fills the gap in the studies of Mucuna pruriens. and Further more in vitro and in vivo studies should be done to explore the potential of these seeds against many diseases, its application as a food source, its antinutrient, and harmful properties as well as its nutraceutical perspective.

Abstract
The structure of the MP-4 protein was previously determined at a resolution of 2.8 Å. Owing to the unavailability of gene-sequence information at the time, the side-chain assignment was carried out on the basis of a partial sequence available through Edman degradation, sequence homology to orthologs and electron density. The structure of MP-4 has now been determined at a higher resolution (2.22 Å) in another space group and all of the structural inferences that were presented in the previous report of the structure were validated. In addition, the present data allowed an improved assignment of side chains and enabled further analysis of the MP-4 structure, and the accuracy of the assignment was confirmed by the recently available gene sequence. The study reinforces the traditional concept that conservative interpretations of relatively low-resolution structures remain correct even with the availability of high-resolution data.

Abstract
The occurrence of conflicting reports on the improvement of male reproductive function among humans fed diet containing the seed of Mucuna pruriens (MP) have raised a major concern in Nigeria. We assessed the effect of MP seed powder on the reproductive function in 32 adult male albino rats randomized to 4 groups of 8 rats each for 8 weeks. Group 1 (control) was given standard rat chow while groups 2, 3 and 4 were fed diets containing MP seed powder at 0.75 g, 1.5 g and 2.25 g respectively. Serum level of follicle stimulating hormone, testosterone, luteinizing hormone, oxidative stress markers in the testis, epididymal sperm quality and cytoarchitectural structure of the testis were monitored using standard methods. Significant improvements (p < 0.05) in the serum levels of all the hormones, testicular antioxidant defence, epididymal sperm quality without testicular degenerative changes were observed in group 2 compared to other groups. Oxidative stress, severe degenerative architectural lesions in the testis as well as significant reductions (p < 0.05) in epididymal sperm count, percentage motility and significant (p < 0.05) increased in abnormal sperm cells were observed in group 4. MP seed enhances reproductive function in male rats only at a dose level of 0.75g. A dose value higher than 0.75 g may be toxic to the male reproductive system.

Abstract
This study was aimed at investigating the antioxidant properties and membrane stabilization effects of Mucuna pruriens leaves on sickle erythrocyte as a possible means of sickle cell disease management. Pulverized plant material was extracted with methanol, filtered and concentrated at reduced pressure with a rotary evaporator. Phytochemical analysis and antioxidant studies of the extract were carried out using standard methods. Blood samples of volunteer sickle cell patients and healthy individuals used in the study were collected from the University of Nigeria Medical Centre and University campus community, Nsukka respectively. The genotypes of the individuals were confirmed by cellulose acetate paper electrophoresis. Water induced haemolysis of human red blood cell was used to assess membrane stabilization of the erythrocytes. Phytochemical result of the extract showed the presence of alkaloids, flavonoids, tannins, proteins, terpenoids, saponins, cardiac glycosides and anthraquinones. Antioxidant vitamins C and E were present in concentrations of 495.36 mg/100 g and 101.03 mg/100 g respectively. The percentage (%) scavenging activity of the 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) and hydroxyl radical by the extract was significant. The extract exhibited membrane stabilization on both normal and sickle erythrocytes. The percentage (%) inhibition of haemolysis by the extract in both normal and sickle erythrocytes at different concentrations of 100, 200, 400, 600 and 800 μg/ml were significant and concentration dependent. We conclude that M. pruriens leaves have antioxidant properties and erythrocyte membrane stabilizing potentials and could be recommended for use in the management of patients with sickle cell anaemia.

Abstract
Type 1 diabetes is an autoimmune disease induced by abnormal insulin secretions from β-cells in pancreas. The present study aimed to investigate the immunosuppressive effects from protein derivatives of Mucuna pruriens on a murine model of Type 1 diabetes. Hydrolyzate and five peptide fractions with different molecular weight were administered orally by 14 days, followed T1D murine model was built by intraperitoneal injection of streptozotocin over 5 days. The mice weight, blood glucose levels, anti-insulin, and anti-pancreatic islet β-cells antibodies, pro-inflammatory cytokines as tumor necrosis factor alpha and interleukin-6 were determined in four times (0, 15, 30, and 45 day). Mice were sacrificed and pancreatic tissues samples were obtained and staining with hematoxylin and eosin to determine the degree of damage. The study demonstrated immunosuppressive activity in four of the six treatment groups: (a) T1D PPH, (b) T1D F 5-10 kDa, (c) T1D F 3-5 kDa, and (d) T1D F 1-3 kDa. PRACTICAL APPLICATIONS: Due to the high content of native protein in seeds of Mucuna pruriens, studies have reported potential in the elaboration of hydrolysates and peptides with biological activity. These protein derivatives could help in the treatment of immunological disorders that are observed in several chronic non-communicable disease and inflammatory diseases, such as T1D. Activated macrophages and lymphoplasmacytic infiltrate plays a crucial role in the initiation and maintenance of T1D; therefore, several studies has focused to reduce the effector functions of this cells for diminishing the clinical manifestations in inmmunocompromised patients. Thus, this study indicates the potential application of hydrolyzate and peptide fractions of M. pruriens in functional foods and dietary supplements could be developed for the treatment of inflammatory and chronic non-communicable diseases.

Abstract
BACKGROUND Protein hydrolysates from food plants, such as legumes, have emerged as a new alternative to treat hyperglycemia, an important risk factor contributing to the development of type 2 diabetes mellitus (T2DM) and its complications. The aim of this work was to assess the antihyperglycemic activity and inhibition of α-glucosidase, and intestinal glucose absorption, and acute toxicity of total hydrolysates and < 1 kDa fractions from Phaseolus lunatus L., Phaseolus vulgaris L., and Mucuna pruriens (L.) DC., obtained by hydrolysis with Alcalase®-Flavourzyme® or pepsine-pancreatin enzymatic systems. RESULTS In vivo results showed that three of six total hydrolysates and four of six < 1 kDa fractions suppressed starch-induced postprandial hyperglycemia (ED50 range between 1.4 and 93 mg kg-1 ). In vitro, total hydrolysates and fractions, particularly from M. pruriens, inhibited carbohydrate intestinal absorption (from 19.2 to 40%), and α-glucosidase activity (IC50 from 0.86 to 75 mg mL-1 ). Finally, none of the hydrolysates and fractions tested did not show any signs of toxicity (LD50 > 5000 mg kg-1 ). CONCLUSION These results suggest that hydrolysates and < 1 kDa fractions from P. lunatus, P. vulgaris and M. pruriens are suitable candidates to treat or prevent T2DM. © 2018 Society of Chemical Industry.

Abstract
INTRODUCTION L-Dopa, a key neurotransmitter used to treat neural disorders such as Parkinson's disease, is found in the seeds of the genus Mucuna at a sufficient concentration for possible commercial use. OBJECTIVE To develop a simple and reliable method to extract L-Dopa from M. pruriens seeds in an aqueous medium and then quantitate this compound using a 1 H qNMR method (internal standard); and also to evaluate the accuracy and reproducibility of this method with an NMR calibration curve. METHODOLOGY The extraction method of L-Dopa from M. pruriens was optimized. The quantitation with single point quantitative NMR (qNMR) and NMR calibration curve was based on the resonance properties of the main functional groups of the L-Dopa molecule, in particular the signals of the three aromatic protons, which were compared with the signal of an internal standard such as syringic acid. The accuracy (precision and trueness) and reproducibility of both NMR techniques were evaluated. RESULTS The methods of single point qNMR and NMR calibration curve, applied to the seeds of two M. pruriens varieties, gave very similar L-Dopa contents: 3.0-3.2% and 3.0-3.1%, respectively. CONCLUSION The statistical analysis confirmed the accuracy and reproducibility of this single point qNMR method (internal standard) for determining L-Dopa, as well as other commercial preparations of this species, without performing an NMR calibration curve.

Abstract
Transcriptome analysis and biochemical characterization of the putative l-3,4-dihydroxyphenylalanine (l-DOPA) pathway in Mucuna pruriens (L.) DC have been performed. Spatio-temporal quantification of the putative l-DOPA biosynthetic pathway genes and its correlation with respective metabolites was established. l-tyrosine, l-DOPA, and dopamine from all plant parts were quantified. The de novo transcriptome analysis was performed using leaves of the selected M. pruriens mutant T-IV-9 during maturity. The putative L-DOPA pathway and its regulatory genes were retrieved from transcriptome data and the L-DOPA pathway was biochemically characterized. The spatial and temporal gene expression for the L-DOPA pathway was identified with respect to the chemical constituents. L-tyrosine, L-DOPA, and dopamine contents were highest in leaves during maturity (about 170-day-old plants). The polyphenol oxidase (PPO) was highly expressed in tender stems (230-fold higher as compared to seeds) as well as a high L-DOPA content. The PPO gene was highly expressed in leaves (3367.93 in FPKM) with a 79-fold increase compared to control plants during maturity. L-DOPA was found in every part with varied levels. The highest L-DOPA content was found in mature dried seed (3.18-5.8%), whereas the lowest amount was recorded in mature and dried leaves. The reproductive parts of the plant had a higher amount of L-DOPA content (0.9-5.8%) compared to the vegetative parts (0.2-0.91%). Various amino acid transporters and permeases were expressed in M. pruriens. The transcripts of dopa decarboxylase (DDC) were found in almost all parts of the plant, but its higher content was limited to the leaf.

Abstract
Aim: n-Propanol extracts from fresh, boiled, and fermented seeds were studied to evaluate their neuroprotective effects in a Parkinson’s disease (PD) rat model, based on the total number of dopaminergic (DA) neurons in the substantia nigra pars compacta (SNpc). Materials and Methods: Rats were induced with paraquat dichloride at a dosage of 7 mg/kg BW intraperitoneally twice a week and at the same time supplemented with extract at a dosage of 70 mg/kg BW orally every day for 3 weeks. On the 24th day, all rats were perfused and fixed with 4% paraformaldehyde. The left part of the SNpc was processed for immunohistochemical staining with tyrosine hydroxylase (TH)-antibody. The total number of DA neurons in SNpc was evaluated with a stereological method. Results: TH-immunoreactive cells found in the SNpc were identified as DA neurons. The average total number of DA neurons in the SNpc increased significantly in the PD rat model that was given an n-propanol extract of boiled and fermented seeds compared with a control PD rat model. Surprisingly, there was no significant difference in the average total number of DA neurons in SNpc between the PD rat model that was given n-propanol extract of fresh seeds and the control PD rat model. Conclusion: n-Propanol extract of boiled and fermented seeds could produce a higher neuroprotective effect against DA neuron than fresh seeds in a PD rat model.

Abstract
Mucuna pruriens (Mucuna) has been prescribed in Ayurveda for various brain ailments including 'kampavata' (tremors) or Parkinson's disease (PD). While Mucuna is a well-known natural source of levodopa (L-dopa), published studies suggest that other bioactive compounds may also be responsible for its anti-PD effects. To investigate this hypothesis, an L-dopa reduced (<0.1%) M. pruriens seeds extract (MPE) was prepared and evaluated for its anti-PD effects in cellular (murine BV-2 microglia and human SH-SY5Y neuroblastoma cells), Caenorhabditis elegans, and Drosophila melanogaster models. In BV-2 cells, MPE (12.5⁻50 μg/mL) reduced hydrogen peroxide-induced cytotoxicity (15.7-18.6%), decreased reactive oxygen species production (29.1-61.6%), and lowered lipopolysaccharide (LPS)-induced nitric oxide species release by 8.9⁻60%. MPE (12.5-50 μg/mL) mitigated SH-SY5Y cell apoptosis by 6.9-40.0% in a non-contact co-culture assay with cell-free supernatants from LPS-treated BV-2 cells. MPE (12.5-50 μg/mL) reduced 6-hydroxydopamine (6-OHDA)-induced cell death of SH-SY5Y cells by 11.85⁻38.5%. Furthermore, MPE (12.5-50 μg/mL) increased median (25%) and maximum survival (47.8%) of C. elegans exposed to the dopaminergic neurotoxin, methyl-4-phenylpyridinium. MPE (40 μg/mL) ameliorated dopaminergic neurotoxin (6-OHDA and rotenone) induced precipitation of innate negative geotaxis behavior of D. melanogaster by 35.3 and 32.8%, respectively. Therefore, MPE contains bioactive compounds, beyond L-dopa, which may impart neuroprotective effects against PD.

Abstract
In the present study, we evaluated the effects of M. pruriens administration on metabolic parameters, oxidative stress and kidney nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and nuclear factor (erythroid-derived 2)-like 2 (Nrf2) signaling pathways in high-fructose fed rats. Male rats (n = 28) were divided into 4 groups as control, M. pruriens, fructose, and M. pruriens plus fructose. All rats were fed a standard diet supplemented or no supplemented with M. pruriens (200 mg/kg/d by gavage). Fructose was given in drinking water for 8 weeks. High fructose consumption led to an increase in the serum level of glucose, triglyceride, urea and renal malondialdehyde (MDA) levels. Although M. pruriens treatment reduced triglyceride and MDA levels, it did not affect other parameters. M. pruriens supplementation significantly decreased the expression of NF-ҡB and decreased expression of Nrf2 and HO-1 proteins in the kidney. This study showed that the adverse effects of high fructose were alleviated by M. pruriens supplementation via modulation of the expression of kidney nuclear transcription factors in rats fed high fructose diet.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Mucuna pruriens (L.) DC (MP) is an ancient Indian medicinal plant traditionally used to treat Parkinson's disease. L-Dopa (LD), precursor of dopamine is abundantly found in the seeds of MP. L-dopa is a natural inhibitor of prolactin (PRL) hormone which is required to maintain lactation in women but it's over production (hyperprolactinemia) plays critical role in advancement of breast cancer. AIM OF THE STUDY We aim to examine the pharmacological effect of LD and MP on this hyperprolactinemia associated breast cancer and related signaling for effective management of the disease. We also investigated chemo-sensitizing effect of MP on hyperprolactinemia-mediated cisplatin resistance. MATERIALS AND METHODS Methanolic seed extract of MP were prepared and analysed using HPLC. Effect of LD and MP on the cellular viability of breast cancer cells (T47D, MCF-7, MDA-MB-468 and MDA-MB-231) were evaluated using MTT assay. Further, effect of LD and MP on colony forming potential, DNA damage, cell cycle distribution and apoptosis was determined using agar/agarose method, comet assay and annexin and PI method followed by FACS analysis. To reveal the molecular mechanism involved in the anti-cancer activity of MP, transcriptional and translational level analysis of the key proteins involved in the PRL-mediated signaling, was performed using RT-PCR and western blot analysis. The effect of MP extract on PRL-mediated signaling was validated using dopaminergic agonist bromocriptine. MP extract and cisplatin was given in different combination with appropriate controls to check their effect on chemo-resistivity of breast cancer cells. RESULTS Our results demonstrated that MP seed extract has the potential to inhibit cellular proliferation of PRL expressing T47D and MCF-7 breast cancer cells via induction of DNA damage, G1 phase of cell cycle arrest and apoptosis more effectively as compare to LD. Further, MP-mediated anti-cancerous effect was associated with the downregulation of PRL expression, further suppressing the JAK2/STAT5A/Cyclin D1 signaling pathway which has been validated using dopaminergic agonist bromocriptine. Cancer-related hyperprolactinemia confers cisplatin resistance, we observed that MP via PRL inhibition, enhances cisplatin efficacy after their combinatorial treatment in breast cancer cells. CONCLUSIONS Collectively, our study suggests that MP could be recommended as dietary supplement along with the chemotherapeutic agents against breast cancer.

Abstract
Velvet bean (Mucuna pruriens) is an efficient cover forage that controls weeds, pathogens and nematodes, and the non-protein amino acid L-3,4-dihydroxyphenylalanine (L-DOPA) is its main allelochemical. The effects of 3 g L-1 of an aqueous extract of velvet bean seeds, along with 0.5 mM L-DOPA for comparison, were evaluated in roots, stems and leaves of soybean (Glycine max). The activities of phenylalanine ammonia lyase (PAL) and cinnamyl alcohol dehydrogenase (CAD) were determined, along with the lignin content and its monomeric composition. The results revealed similar effects caused by L-DOPA and the aqueous extract. Both treatments reduced PAL and CAD activities, lignin, and lignin monomer contents in roots; PAL and CAD activities in stems, and CAD activity in leaves. These findings provide further evidence that the effects of velvet bean cover forage on root lignification were due to the L-DOPA, its major allelochemical.

Abstract
Mucuna pruriens is a well-known legume for the itching attributes of the trichome and a valuable medicinal herb that is used for the treatment of Parkinson's disease, sexual debilities, etc. Its cultivation was deprived due to its itching behavior. The wild genotype of M. pruriens have the largest trichome length (2015 ± 29 μm) compared to other genotype and mutants. The white-seeded variety of M. pruriens was found to be the most suitable for large-scale cultivation due to the small trichome size and less trichome density on the pod. The external surface trichomes have protuberance with unknown function. The unicellular trichomes of Mucuna show the flowing fluid or cytoplasm inside the trichome. The unigenes regulating the differentiation and development of the trichome such as GLABRA-1, GLABRA-2, and cpr-5 have been identified in M. pruriens transcriptome of the leaf. The Mucunain shows a higher transcript abundance in the flower and pod cover compared to the seeds. The Mucunain was found in every stage of plant growth, but it was highly expressed during maturity (about 170 days) with a high fragment per kilobase per million value.

Abstract
Till date, drugs that have been used to manage Parkinson’s disease (PD) have only shown symptomatic relief with several adverse effects besides their inability to prevent neurodegeneration. Neuroinflammation plays an important role in the advancement of PD and can be targeted for its effective treatment. Researchers have suggested that herbal plants exhibiting the anti-inflammatory and anti-oxidant properties are therefore beneficial to human health. Conventionally, Mucuna pruriens (Mp) seeds are used for maintaining male virility in India. Reportedly, Mp is used as a rejuvenator drug having neuroprotective property. Our study aimed to investigate effects of aqueous extract of Mp (100 mg/kgbwt) on neuroinflammation, orally administered to mice intoxicated with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) as well as the molecular mechanism involved in the progression of PD. In this study, we have observed significant behavioral abnormalities beside decreased antioxidant defense in MPTP intoxicated mice. We have also observed significant increase in inflammatory parameters like Glial Fibrillary Acidic Protein, Inducible Nitric Oxide Synthase, Intercellular Cell Adhesion Molecule, and Tumor Necrosis Factor alpha in substantia nigra pars compacta (SNpc) of parkinsonian mice, while Mp treatment has notably reduced these inflammatory parameters. Mp also inhibited the MPTP induced activation of NF-κB and promoted pAkt1 activity which further prevented the apoptosis of the dopaminergic neurons. Moreover, Mp exhibited significant antioxidant defense by inhibiting the lipid peroxidation and nitrite level, and by improving catalase activity and enhancing GSH level in nigrostriatal region of mouse brain. Mp also recovered the behavioral abnormalities in MPTP treated mice. Additionally, Mp treatment considerably increased the immunoreactivity of Tyrosine Hydroxylase and Dopamine Transporter in SNpc of parkinsonian mice. Our high performance liquid chromatography analysis of the Mp seed extract have shown L-DOPA, gallic acid, phytic acid, quercetin, and catechin equivalents as the major components which might cause neuroprotection in PD mice. Our result suggested that Mp extract treatment containing L-DOPA and a mixture of rich novel phytochemicals significantly alleviates the MPTP induced neurotoxicity by NF-κB and pAkt pathway. The findings observed thereby indicate that Mp extract have suggestively ameliorated MPTP induced neuroinflammation, restored the biochemical and behavioral abnormalities in PD mouse and thus provided a scientific basis for its traditional claim.

Abstract
OBJECTIVES Mucuna pruriens (MP) seeds contain levodopa (up to 2% by weight) and have been used in traditional Indian medicine to treat an illness named "Kampavata," now understood to be Parkinson's disease (PD). Studies have shown MP to be beneficial, and even superior, to levodopa alone in treating PD symptoms. Commercial products containing MP are readily available from online and retail sources to patients and physicians. Products often contain extracts of MP seeds, with significantly higher levodopa content than the seeds. However, MP products have limited regulatory controls with respect to quality and content of active ingredient. The aim of this study was to apply a quantitative method to determine levodopa content in readily available MP products that might be used by patients or in research studies. DESIGN Levodopa present in six commercial MP products was quantified by solvent extraction followed by reversed-phase high-performance liquid chromatography (HPLC) coupled to fluorescence detection (FD). Certificates of analysis (COA) were obtained, from manufacturers of MP products, to assess the existence and implementation of specifications for levodopa content. RESULTS HPLC-FD analysis revealed that the levodopa content of the six commercial MP products varied from 6% to 141% of individual label claims. No product contained levodopa within normal pharmacopeial limits of 90%-110% label claim. The maximum daily dose of levodopa delivered by the products varied from 14.4 to 720 mg/day. COAs were inconsistent in specifications for and verification of levodopa content. CONCLUSIONS The commercial products tested varied widely in levodopa content, sometimes deviating widely from the label claim. These deficiencies could impact efficacy and safety of MP products used by PD patients and compromise the results of scientific studies on MP products. The HPLC-FD method described in this study could be utilized by both manufacturers and scientific researchers to verify levodopa content of MP products.

Abstract
Background In the search of safe and effective lead molecules from natural sources, Mucuna pruriens (MP) L. (Fabaceae) seeds were utilized for exploring the antihypertensive potential. Traditionally, it is used as diuretic and hypotensive. Methods Bioassay-guided fractions were utilized for the isolation of active compounds by column chromatography. IC50 value, enzyme kinetics and inhibition mechanism were determined. In vivo time and dose-dependent hypotensive study followed by changes in mean arterial pressure (MAP) induced by angiotensin I (3 nmol/kg), angiotensin II (3 nmol/kg), and bradykinin (10 nmol/kg) in anesthetized rats was done. Plasma and tissue angiotensin I-converting enzyme (ACE) activities were also determined. Results Phytochemical analysis by spectroscopic techniques revealed the presence of known compounds like genistein, ursolic acid and L-DOPA from the ethyl acetate and water fraction, respectively. In vitro study revealed MP ethyl acetate (MPEA) fraction and genistein as the most active fraction (IC50 156.45 µg/mL) and compound (IC50 253.81 µM), respectively. Lineweaver-Burk plots revealed a non-competitive mode of inhibition. ACE protein precipitation was the suggested mechanism for inhibition. The extract showed a time- and dose-dependent decrease in MAP. Genistein was able to dose-dependently reduce the MAP, up to 53±1.5 mmHg (40 mg/kg, i.v.). As compared to control, it showed a dose-dependent decrease in plasma ACE activity of 40.61 % and 54.76 % at 10 mg/kg and 20 mg/kg, respectively. It also decreased the ACE activity in the aorta (107.67nM/ml min at 10 mg, p<0.001; 95.33nM/ml min at 20 mg p<0.001). Captopril was used as a standard for various in vitro and in vivo assays. Conclusions The study revealed the antihypertensive potential of MP seed compounds via ACE inhibition.

Abstract
Background The medicinal legume Mucuna pruriens (L.) DC. has attracted attention worldwide as a source of the anti-Parkinson’s drug L-Dopa. It is also a popular green manure cover crop that offers many agronomic benefits including high protein content, nitrogen fixation and soil nutrients. The plant currently lacks genomic resources and there is limited knowledge on gene expression, metabolic pathways, and genetics of secondary metabolite production. Here, we present transcriptomic resources for M. pruriens, including a de novo transcriptome assembly and annotation, as well as differential transcript expression analyses between root, leaf, and pod tissues. We also develop microsatellite markers and analyze genetic diversity and population structure within a set of Indian germplasm accessions. Results One-hundred ninety-one million two hundred thirty-three thousand two hundred forty-two bp cleaned reads were assembled into 67,561 transcripts with mean length of 626 bp and N50 of 987 bp. Assembled sequences were annotated using BLASTX against public databases with over 80% of transcripts annotated. We identified 7,493 simple sequence repeat (SSR) motifs, including 787 polymorphic repeats between the parents of a mapping population. 134 SSRs from expressed sequenced tags (ESTs) were screened against 23 M. pruriens accessions from India, with 52 EST-SSRs retained after quality control. Population structure analysis using a Bayesian framework implemented in fastSTRUCTURE showed nearly similar groupings as with distance-based (neighbor-joining) and principal component analyses, with most of the accessions clustering per geographical origins. Pair-wise comparison of transcript expression in leaves, roots and pods identified 4,387 differentially expressed transcripts with the highest number occurring between roots and leaves. Differentially expressed transcripts were enriched with transcription factors and transcripts annotated as belonging to secondary metabolite pathways. Conclusions The M. pruriens transcriptomic resources generated in this study provide foundational resources for gene discovery and development of molecular markers. Polymorphic SSRs identified can be used for genetic diversity, marker-trait analyses, and development of functional markers for crop improvement. The results of differential expression studies can be used to investigate genes involved in L-Dopa synthesis and other key metabolic pathways in M. pruriens.

Abstract
OBJECTIVE To investigate the biological effects of the Mucuna pruriens (M. pruriens) seed extracts that lacked l-DOPA, which was formerly reported as the active ingredient, on erectile dysfunction (ED) both in vitro and in vivo. METHODS Seed of M. pruriens plant that cultivated in Mae Taeng District, Chiang Mai Province, Thailand, was collected. Component of its seeds were extracted and isolated into 2 fractions using methanol, polar and nonpolar. Each fraction was investigated for phytochemicals using gas chromatography and mass spectroscopy and was screened for biological activity in vitro using three different cell lines. The most biological active fraction was used to treat both streptozotocin (STZ)-induced diabetes mellitus-erectile dysfunction (DM-ED) male Wistar rats and normal rats (n = 6 per groups) to compare the effect on sexual behavior parameters, including number of intromission, mounting and ejaculation, with that of rats given Sildenafil by individually pairing with their female counterparts. Penile tissues and serums were collected to determine histological structure, related gene expression and biomolecules. RESULTS The phytochemicals of the polar fraction were possibly catechol and its derivatives plus polyphenols, whereas the nonpolar fraction consisted of lipid derivatives. l-DOPA was not detected in either of the extracts. The polar fraction was able to up-regulate the expression of ED-related genes including eNOS and nNOS in vitro which subsequently promotes nitric oxide production and maintains intracellular cyclic guanosine monophosphate levels. When administrated to DM-ED rats, the polar extract significantly improved all sexual behavior parameters in DM-ED rats compared to untreated group (18.3 ± 1.8 to 10.8 ± 2.9 for intromission, 9.8 ± 2.2 to 5.7 ± 1.3 for mounting, and 1.8 ± 0.6 to 0.2 ± 0.4 for ejaculation). That effect might due to the ability of the extract to stimulate the expression of eNOS and nNOS which results in nitric oxide production and subsequently maintains cyclic guanosine monophosphate levels in penile tissue. Moreover, this extract may also prevent penile tissue deterioration due to diabetes. CONCLUSIONS The polar extract of M. pruriens seed can be used for ED therapy, especially in patients with metabolic diseases including diabetes. The action of the extract might be due to catechol and its derivatives and polyphenols.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Medicinal plants like Mucuna pruriens L.(DC) and Withania somnifera L.(Dunal) have been used in traditional Ayurvedic medicine to manage neurodegenerative diseases like Parkinson's disease. AIM The aim of this review is to share the role of Ayurveda's insights, traditional usage and contemporary investigations for translational, integrative applications to manage Idiopathic Parkinson's Disease. MATERIALS AND METHODS High impact journals for Parkinson's diseases, traditional textbooks from Ayurveda as well as relevant clinical and para clinical studies with botanicals are selectively incorporated to evolve the aforesaid translational application. RESULTS . A. CONTEMPORARY UNDERSTANDING AND EXISTING THERAPEUTIC GAPS Parkinson's disease (PD) is a complex multi-system, neurodegenerative disease. Though predominantly perceived as a motor disease, it also has debilitating non- motor features, which are frequently missed and not treated. Major treatment goals are to increase striatal dopamine levels with precursor-substitution and/or reduce its breakdown. As the disease progresses, a steady increase in the dose of levodopa is inevitable. However, higher doses cause motor complications of dyskinesia and dystonia and compromise medical treatment. B. ROLE OF MUCUNA PRURIENS L.DC), THE MOST PROMISING BOTANICAL FROM AYURVEDA: Ayurveda offers a natural source of levodopa - the seeds of Mucuna pruriens L.(DC)- which have a long standing safe use in the condition. Its clinical studies have shown pharmacokinetic profile distinct from synthetic levodopa, which is likely to reduce the untoward motor complications. Additionally, its seed extracts have shown neuroprotective benefits which are unrelated to levodopa. C. AYURVEDIC REGIMENS AND MEDICINAL PLANTS FOR NEUROPROTECTIVE AND SYMPTOMATIC BENEFITS: Other regimens (Panchakarma) and medicinal plants used in Ayurveda have been subjected to exploratory studies with promising early results in the condition. The debilitating non motor symptoms in patients have shown response with one of the regimens - medicated oil enema (basti). Effects of two medicinal plants Withania somnifera(L.)Dunal and Curcuma longa Linn in Parkinson's Disease related models have been discussed in detail. We have also shared a shortlist of medicinal plants most likely to be useful in management of specific features of the disease such as cognitive decline, mood disorders, risk of osteoporosis amongst others. CONCLUSION Ayurveda with its medicinal plants and treatment approaches, can strengthen the therapeutic armamentarium of PD to improve clinical outcomes, if these leads are systematically further investigated by well-designed longer term studies.

Abstract
Background Mucuna pruriens, Tribulus terrestris and Ashwagandha (Withania somnifera) are widely known as antioxidant effective herbals and have been reported to possess aphrodisiac activities in traditional usages. In this study, we determined the effects of these herbals on sexual functions, serum biochemical parameters, oxidative stress and levels of NF-κB, Nrf2, and HO-1 in reproductive tissues. Methods Thirty-five male rats were divided into five groups: the control group, sildenafil-treated group (5 mg/kg/d), Mucuna, Tribulus and Ashwagandha groups. The extract groups were treated orally either with Mucuna, Tribulus or Ashwagandha (300 mg/kg b.w.) for 8 weeks. Results All of the extracts were found to be significantly effective in sexual functioning and antioxidant capacity and Tribulus showed the highest effectiveness. Serum testosterone levels significantly increased in Tribulus and Ashwagandha groups in comparison to control group. Tribulus was able to reduce the levels of NF-κB and increase the levels of Nrf2 and HO-1 to a much greater extent than Mucuna and Ashwagandha. Conclusions These results demonstrate for the first time that Mucuna, Tribulus and Ashwagandha supplementation improves sexual function in male rats via activating Nrf2/ HO-1 pathway while inhibiting the NF-κB levels. Moreover, Tribulus terrestris extract was found to be more bioavailable from Ashwagandha extract followed by Mucuna extract.

Abstract
The present work was carried out to evaluate the nutritive quality (proximate and antinutrients composition) of vegetable milks prepared from whole and dehulled mucuna bean flours. Casein and mucuna milk diets were fed to rats (four weeks old; n = 8 per group) for 28 days to determine protein efficiency ratio (PER), net protein efficiency ratio (NPER), true and apparent digestibility (TD and AD, respectively), organ-to-body weight ratios and hematological parameters. The experimental design was a factorial design with two variety of mucuna (cochinchinensis and veracruz) and two treatments (whole and dehulled beans). Protein, total sugar, dry matter and ash-content of mucuna milks ranged from 6.40 to 12.13 g/100 mL, 10.52 to 13.08 g/100 mL, 8.59 to 12.88 g/100 g and 0.31 to 0.92 g/100 g, respectively. Milks from dehulled flours had lower contents of tannins (80-87.08 %), phytates (76.67-78.16 %) and L-Dopamine (44.45-66.66 %) than that from whole flours. The PER of dehulled mucuna diets were 22.76-21.74 %, but negative PER and low NPER was observed for whole mucuna milk diets. TD for dehulled mucuna milk (85.15-85.96 %) were higher and similar to casein when compared to that of whole mucuna milk (47.87-51.17 %). Rats fed with diets containing whole mucuna milk lost weight and had higher kidney weight. In addition, the rats fed with milk from whole mucuna flours showed significantly lower levels of lymphocytes, granulocytes, red blood cells, hemoglobin and hematocrit than that fed with dehulled mucuna milk.

Abstract
BACKGROUND Parkinson's disease (PD) is a progressive neurological condition. Levodopa (LD) is the gold standard therapy for PD patients. Most PD patients in low-income areas cannot afford long-term daily Levodopa therapy. The aim of our study was to investigate if Mucuna pruriens (MP), a legume with high LD content that grows in tropical regions worldwide, might be potential alternative for poor PD patients. METHODS We analyzed 25 samples of MP from Africa, Latin America and Asia. We measured the content in LD in various MP preparations (dried, roasted, boiled). LD pharmacokinetics and motor response were recorded in four PD patients, comparing MP vs. LD+Dopa-Decarboxylase Inhibitor (DDCI) formulations. RESULTS Median LD concentration in dried MP seeds was 5.29%; similar results were obtained in roasted powder samples (5.3%), while boiling reduced LD content up to 70%. Compared to LD+DDCI, MP extract at similar LD dose provided less clinical benefit, with a 3.5-fold lower median AUC. CONCLUSION Considering the lack of a DDCI, MP therapy may provide clinical benefit only when content of LD is at least 3.5-fold the standard LD+DDCI. If long-term MP proves to be safe and effective in controlled clinical trials, it may be a sustainable alternative therapy for PD in low-income countries.

Abstract
Ayurveda, an ancient system of medicine that is indigenous to India, is believed to be the world's oldest comprehensive health-care system and is now one of the most recognized and widely practiced disciplines of alternative medicine in the world. Medicinal herbs have been in use for treating diseases since ancient times in India. Ayurvedic therapies with medicinal herbs and herbomineral products generally provide relief without much adverse effects even after prolonged administration. Neurodegenerative disorders are a major cause of mortality and disability, and increasing life spans represent one of the key challenges of medical research. Ayurvedic medicine describes most neurodegenerative diseases and has defined a number of plants with therapeutic benefits for the treatment of neurodegenerative diseases having antioxidant activities. In this chapter, the role of four important Ayurvedic medicinal plants, viz., Withania somnifera (ashwagandha), Bacopa monnieri (brahmi), Centella asiatica (gotu kola), and Mucuna pruriens (velvet bean), on neurodegenerative diseases are discussed.

Abstract
AIM Hepatotoxicity is a significantly increasing health problem worldwide, and the extent of the problem has stimulated interest in the search for hepatotherapeutic agents from plants. This study investigated the hepatoprotective and in vivo antioxidant activities of the hydroethanolic extract of Mucuna pruriens leaves in antitubercular and alcohol-induced hepatotoxicity assays in rats. METHOD In each of the models used, seven groups were allotted. The different groups received normal saline (10 mL·kg(-1), p.o.); hepatotoxicant (isoniazid-rifampicin, INH-RIF, 100 mg·kg(-1), i.p. or 20% ethanol 5 g·kg(-1), p.o.) and normal saline (10 mL·kg(-1), p.o.); hepatotoxicant and extract at doses of 100, 200, and 400 mg·kg(-1) p.o.; hepatotoxicant and silymarin 50 mg·kg(-1) p.o.; and extract at 400 mg·kg(-1) p.o. On the 21(st) day of treatment, blood was collected for assessment of serum biochemical parameters and harvested liver samples were assessed for antioxidants. RESULTS The hepatotoxicants significantly (P < 0.05-0.001) increased the levels of alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), bilirubin, and malondialdehyde (MDA); and reduced the levels of catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx), and reduced glutathione GSH compared to control. M. pruriens significantly reversed (P < 0.05-0.001) the elevation in the level of ALT, AST, ALP, and bilirubin caused by the hepatotoxicants. The extract (200 and 400 mg·kg(-1)) significantly reversed (P < 0.05) the diminution in the level of in vivo antioxidants and increased the level of MDA produced by INH-RIF. M. pruriens (100-400 mg·kg(-1)) elicited significant reduction (P < 0.001) in the level of MDA compared to the alcohol group. Silymarin also reversed the deleterious effects of the hepatotoxicants. CONCLUSION The hydroethanolic extract of Mucuna pruriens leaves possesses hepatoprotective activity with enhancement of in vivo antioxidants as a possible mechanism of action.

Abstract
BACKGROUND The effects of antidepressant treatments have traditionally been discussed primarily in terms of effects on noradrenergic and serotonergic systems. Multiple lines of investigation have also explored the role of dopaminergic systems in mental depression. Seed of Mucuna pruriens Linn. (DC) (Leguminoseae) is well-known with dopaminergic action and has several therapeutic applications in folk medicine in curing or managing a wide range of diseases including Parkinsonism. AIM To elucidate the anti-depressent profile and possible dopaminergic modulating action of M. pruriens seeds in various experimental models of depression. MATERIALS AND METHODS In the present study, antidepressant effect of the hydroalcoholic extract of the M. pruriens seeds (MPE) (100 and 200 mg/kg, p.o.) was investigated in the Forced Swimming Test (FST), Tail Suspension Test (TST), and Chronic Unpredictable Mild Stress (CUMS) test in mice. Further, dopaminergic interaction of same doses of MPE in the FST and TST were checked by the administration of a haloperidol (0.1 mg/kg, i.p.) and bromocriptine (2 mg/kg, i.p.) on the 7(th) day of MPE treatment. Effect of MPE on locomotor activity was also checked using actophotometer. RESULTS MPE produced a significant reduction of the immobility time in the FST and TST. Further, antidepressant action of MPE was significantly inhibited by haloperidol and potentiated by bromocriptine in the FST and TST. 21 days of MPE treatment produced protection in CUMS as indicated by a significant increase of sucrose intake of stressed mice. Locomotor activities of mice were not significantly changed after 1 h and 7(th) day of the MPE treatment. CONCLUSION The results of this study indicate that hydroalcoholic extract of MPE have antidepressant action, which may be mediated by an interaction with the dopaminergic system.
