[PMID: 37942157 PMCID: PMC10628661 DOI: 10.1016/j.heliyon.2023.e21139] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Revised: 09/30/2023] [Accepted: 10/17/2023] [Indexed: 11/10/2023] Open
Abstract
We studied the effect of Ajuga iva leaves extract (AIE) on the intestinal absorption, motricity and its antioxidant capacity against diarrhea. Wistar rats were divided and received either: castor oil (CO), CO and loperamide or CO and different doses of AIE. AIE prevented dose-dependently CO-induced diarrhea. AIE at 800 mg/kg showed inhibition efficiency on defecation and diarrhea. The pro-oxidant effect of the CO in the small intestine was inhibited significantly in presence of AIE: increasing glutathione peroxidase (GPx) activity and lowering oxygen free radicals (OH°, O2°-), carbonyl protein and malondialdehyde (MDA) levels. However, co-administration of AIE in castor oil-exposed groups significantly increased the intestinal contents of calcium and magnesium. AIE exhibits significant anti-diarrheal activity, related in part to its antioxidant properties. Our investigation also provides experimental evidence for the traditional use of this medicinal plant in the treatment of diarrhea.

Fakchich J, Elachouri M. An overview on ethnobotanico-pharmacological studies carried out in Morocco, from 1991 to 2015: Systematic review (part 1). JOURNAL OF ETHNOPHARMACOLOGY 2021; 267:113200. [PMID: 32750461 DOI: 10.1016/j.jep.2020.113200] [Citation(s) in RCA: 26] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/24/2019] [Revised: 07/08/2020] [Accepted: 07/16/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The full bibliometric records of data retrieved from ethnobotanical field studies carried out in Morocco (1991-2015) was quali-quantitatively analysed. Despite the importance of traditional medicinal uses in Morocco, any comments about the methodologies and approaches adopted by reviewed studies have been undertaken. Include more data about the importance of traditional medicinal uses in Morocco. AIM OF THE STUDY Three key points were targeted in this review: (i) to contribute to original compilation of medicinal plants traditionally used by people at whole Morocco, by gathering and documenting the current status of these ancestral medical practices, (ii) to provide a novel insight into the relationship between local and biomedical disease concepts in Moroccan society, taking into account health-related beliefs, and their influences on medicinal plant uses, (iii) to figurout the weaknesses and the strengths of the conceptual approches and methods adopted by researchers in ethnobotanical field works. MATERIALS AND METHODS With the help of a computerized database querying, we conducted an extensive literature search respecting our integration criteria. We performed this bibliographic research by using the following search engines available over the Web: Google Scholar, PUBMED, Sciencedirect, Current Content Connect, SCOPUS, SPRINGER LINK, GLOBAL PLANTS, Cochrane Library and SCIRUS. The scientific names listed in the present paper have been validated according to the "The Plant List" and the African Plants Database in order to standardize ethnobotanical data on an international level. For the analysis of data gathered, quali-quantitative analyses have been performed. RESULTS A total of 905 medicinal plant species belonging to 116 families and 726 genera have been selected from 63 published articles. The dominant families were ASTERACEAE (111 species) followed by the FABACEAE (77 species), LAMIACEAE (75 species) and APIACEAE (46 species). The plant species listed are used to cure several public ailments. The digestive ailments represented the most important category (494 species) followed by dermatological diseases (407 species), diabetes (315 species) and urinary diseases (277 species). We assigned the importance of the plant species by several measures (including Frequency Cited (FC), Number of Uses (NU), Number of Respondents (NR) and Index of Performance (IP). The ICF (Informant Consensus Factor) calculated was important in all categories of diseases averaging 47%. CONCLUSION The results obtained, which cover the whole country, delineate the profile of rich wealth of indigenous knowledge on traditional uses of medicinal plants heald by Moroccan society. The total number of 905 plant species listed in this paper, are currently being utilized as medicines and the number is expected to grow as infrastructure allows greater access to unexplored parts of the country. Furthermore, the know how, regarding the plants used, is consistent because the ICF has recorded important values for most diseases treated. Furthermore, in the present paper, we suggested, for authors, some useful recommendations for ethnobotanical field works such as the respect of ethnobotanical standards including checklist of plants with international data base, the deposited voucher specimens, sampling and collection methods.

Abstract
Diabetes is a global health problem, and the number of diabetic patients is in continuous rise. Conventional antidiabetic therapies are associated with high costs and limited efficiency. The use of traditional medicine and plant extracts to treat diabetes is gaining high popularity in many countries. Countries in the Middle East region have a long history of using herbal medicine to treat different diseases, including diabetes. In this review, we compiled and summarized all the in vivo and in vitro studies conducted for plants with potential antidiabetic activity in the Middle East region. Plants of the Asteraceae and Lamiaceae families are the most investigated. It is hoped that this review will contribute scientifically to evidence the ethnobotanical use of medicinal plants as antidiabetic agents. Work has to be done to define tagetes, mechanism of action and the compound responsible for activity. In addition, safety and pharmacokinetic parameters should be investigated.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ajuga iva (L.,) Schreb (A. iva). is a medicinal plant commonly used in Africa to treat several diseases such as diabetes, rheumatism, allergy, cancer, renal, metabolic disorders, cardiovascular disorders, digestive, and respiratory disorders. AIM OF THE REVIEW We highlighted previous reports on A. iva including its ethnopharmacological uses, the chemistry of its secondary metabolites, in vitro and in vivo pharmacological properties, and toxicological evidence. MATERIALS AND METHODS The data on A. iva were gathered using scientific research databases such as ScienceDirect, PubMed, SpringerLink, Web of Science, Scopus Wiley Online, and Google Scholar. In this review, studies focused on A. iva and its phytopharmacological activities were explored. RESULTS A. iva is used by many North African folk medicine practitioners especially against diabetes and immunological diseases. Our analysis of the previous reports confirmed the scientific evidence of A. iva ethnomedicinal uses, especially the antidiabetic and anti-hypercholesterolemia activity. However, there was no clear correlation between previous pharmacological reports on A. iva and its other ethnomedicinal uses in the treatment of rheumatism, allergy, metabolic, digestive, and respiratory disorders. The extracts and isolated compounds from A. iva exhibited numerous in vitro and in vivo pharmacological activities such as antidiabetic, antioxidant, antimicrobial, anti-hypercholesterolemia, insecticide, and litholitic effects. Chemical characterization using GC-MS, HPLC, and NMR revealed the presence of many chemical compounds such as 20-hydroxyecdysone, cyasterone, ajugasterone, apigenin dihexoside, apigenin, carvacrol, ecdysterone, palmitic acid in different parts of A. iva. These compounds belong to different classes of chemical compounds such as steroids, flavonoids, fatty acids, and terpenoids. CONCLUSIONS A. iva extracts especially from the leaves showed significant antidiabetic, antioxidant, anti-hypercholesterolemia, and analgesic effects. Future studies are required to validate the results of clinical trials on A. iva antidiabetic, anti-hypercholesterolemia, antioxidant/anti-inflammatory, antimicrobial, and analgesic properties. Toxicological validation and pharmacokinetics investigation are necessary to validate the efficacy and safety A. iva extracts and its secondary metabolites. An in-depth investigation is needed to reveal the biological activity of A. iva active compounds in preventing the development of cancer and neurodegenerative disorders such as Alzheimer's and Parkinson's diseases.

Abstract
The present review is aimed at providing a comprehensive summary of the botanical characteristics, ethnomedicinal uses, phytochemical, pharmacological, and toxicological studies of the genus Ajuga L. The extensive literature survey revealed Ajuga L. species to be a group of important medicinal plants used for the ethnomedical treatment of rheumatism, fever, gout, sclerosis, analgesia, inflammation, hypertension, hyperglycemia, joint pain, palsy, amenorrhea, etc., although only a few reports address the clinical use and toxicity of these plants. Currently, more than 280 chemical constituents have been isolated and characterized from these plants. Among these constituents, neo-clerodane diterpenes and diterpenoids, phytoecdysteroids, flavonoids, and iridoids are the major bioactive compounds, possessing wide-reaching biological activities both in vivo and in vitro, including anti-inflammatory, antinociceptive, antitumor, anti-oxidant, antidiabetic, antimicrobial, antifeedant, antidiarrhoeal, hypolipidemic, diuretic, hypoglycaemic, immunomodulatory, vasorelaxant, larvicidal, antimutagenic, and neuroprotective activity. This review is aimed at summarizing the current knowledge of the ethnomedicinal uses, phytochemistry, biological activities, and toxicities of the genus Ajuga L. to reveal its therapeutic potentials, offering opportunities for future researches. Therefore, more focus should be paid to gathering information about their toxicology data, quality-control measures, and the clinical application of the bioactive ingredients from Ajuga L. species.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Plants are traditionally used in Algeria to treat many disorders, including diabetes mellitus. Knowledge of the plants that are used may provide insight on their properties, for further exploration. This study reviewed all the available published and unpublished reports concerning the use of herbal medicines in the treatment of diabetes in Algeria. AIM OF THE STUDY To describe the plants used in Algeria to treat diabetes, as reported in the literature. MATERIAL AND METHODS Systematic review of ethnobotanical papers published in the medical literature, from literature databases (Pubmed, Web of Science), as well as Google, for English, French and Arabic -language publication, and a manual search of local libraries and bookshops, as well as the university repository of PhD and master's theses. The reference lists of the papers retrieved were also examined for further papers. RESULTS Many plants are cited in the ethnobotanical surveys, but only very few pharmacological studies were found. In the ethnobotanical surveys, 171 plants were reported, from 58 families of which the most often cited were Asteraceae, Lamiaceae and Apiaceae. The plants with the best evidence of use and activity are: Anabasis articulata (Forssk.) Moq., Trigonella foenum-graecum L., Centaurium erythraea Rafn, Artemisia herba-alba Asso, Marrubium vulgare L., Agathophora alopecuroides (Delile) Fenzl ex Bunge, Anabasis articulata (Forssk.) Moq., Hammada elegans (Bunge) Botsch., Helianthemum kahiricum Delile, Salsola baryosma (Schult.) Dandy, Salsola vermiculata L., Olea europaea L. CONCLUSION Traditional herbal medicines are still very much used in Algeria to control diabetes. However they are generally poorly characterized and none have been properly tested in man. There is a need for systematic evaluation of the more commonly used plants to confirm their antidiabetic activity, identify possible mechanimss of action, and recommend best use.

Abstract
This study investigated the chemical composition, in vivo antioxidant, and antihyperlipidemic potential of Ajwa date polyphenol extract (DPE). Chemical analysis revealed that the Ajwa dates contain substantial amounts of carbohydrates, energy, potassium, iron, polyphenols, and flavonoids. In vivo studies showed that feeding rats with cholesterol-rich diets significantly (p ≤ 0.05) increased their body and liver weights, total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), very-low-density lipoprotein cholesterol (VLDL-C), and triglycerides (TG) in plasma and liver, and reduced the high-density lipoprotein cholesterol (HDL-C) content and antioxidant enzyme activities. However, oral administration of 25, 50, and 100 mg DPE/kg body weight to hypercholestrolemic rats, significantly (p ≤ 0.05) reduced their body and liver weights, total hepatic cholesterol, LDL-C, VLDL-C, and triglycerides. Furthermore, treatment with DPE improved (p ≤ 0.05) the HDL-C concentration and antioxidant enzyme activity in a concentration-dependent fashion, thereby regulating lipid profiles, enhancing the antioxidant defense system. Overall, DPE showed significant (p ≤ 0.05) nutritional, antioxidants, and antihyperlipidemic benefits. PRACTICAL APPLICATIONS: Coronary heart disease is the leading cause of death in the world. Consumption of fruits and vegetables rich in polyphenol have shown to exert cardio-protective effect. This work revealed that phenolic extracts of Ajwa dates have positive impacts on the health as it reduced TC, LDL-C, and lipids VLDL-C and improved HDL-C and the antioxidant defense system in rats. The findings of this study could aid in the profound understanding of the nutritional and health potentials of Ajwa dates and thus could help in utilization of these valuable fruits for the prevention and curing of cardiovascular diseases.

Abstract
Non-nutritive sweeteners (NNS) are increasingly being used by diabetics, but little is known about their effects on antioxidant status. We investigated the effects of ad libitum consumption of commercially available NNS (aspartame, saccharin, sucralose, and cyclamate-based sweeteners) on antioxidative markers in a rat model of type 2 diabetes (T2D). NNS consumption reduced (p < 0.05) T2D-induced lipid peroxidation and boosted serum, hepatic, renal, cardiac, and pancreatic glutathione (GSH) levels. Catalase, glutathione reductase, superoxide dismutase, and glutathione peroxidase activity was increased in the serum and most organs upon diabetes induction, perhaps due to adaptative antioxidant response to the diabetes-induced lipid peroxidation. NNS showed varying effects on serum and tissue antioxidant enzymes of animals. An antioxidant capacity scores sheet of NNS, suggest that aspartame-based NNS may not exert antioxidant effects in diabetics, while saccharin-based NNS may be a potent antioxidative sweetener as seen in the animal model of T2D. PRACTICAL APPLICATIONS: The use of NNS is becoming more popular, especially for diabetic individuals. While there are several commercial NNS available in the market, little is known about how they affect the antioxidant status of consumers. We therefore investigated how some commercially available NNS affect the antioxidant status of diabetic rats. Observed data revealed varying effects of NNS on serum and different organs, which suggest that some NNS may be better than others for diabetic oxidative stress and thus may be recommended for consumers. However, this finding is subject to additional corroborative clinical studies.

Abstract
Purpose
Watermelon (Citrullus lanatus) fruit and its rind are known to contain phytochemicals that may have health benefits. The aim of this paper is to investigate the potential hypocholesterolemic effect of watermelon fruit rind (WR) using rats who are fed a high-cholesterol diet.
Design/methodology/approach
Rats were divided into six groups and fed diets for eight weeks containing normal control diet or normal control diet with either 1% cholesterol, 5% WR, 10% WR, 1% cholesterol + 5% WR or 1% cholesterol + 10% WR. Triglycerides, total cholesterol and lipoprotein levels in serum and liver samples were determined, and histopathological examination of liver tissues was carried out.
Findings
Diets containing 1% cholesterol led to hypercholesterolemia, characterized by increased levels of total cholesterol and low-density lipoproteins in rat serum and liver samples. Incorporation of 10% WR into the diet of the otherwise hypercholesterolemic rats led to significant reduction in serum levels of total cholesterol (from 266.2 to 222.7 mg/dL) and low-density lipoproteins (from 159.5 to 94.4 mg/dL). In addition, these rats also exhibited improvements in hepatic tissue structure compared to the hypercholesterolemic rats.
Originality/value
These results support the potential use of WR as a hypocholesterolemic agent. Further research is needed to ascertain the hypocholesterolemic effect of WR in human.

Abstract
The effects of Virgin coconut oil as an adjuvant to highly active antiretroviral therapy (HAART) were investigated on the testicular ultrastructure and biochemical markers in rats. Twenty male Sprague-Dawley rats, weighing 153-169 g were divided into four groups and treated as follows: control A (distilled water), B (HAART), C (HAART+Virgin coconut oil 10 ml/kg) and D (Virgin coconut oil [VCO] 10 ml/kg). Testicular segments were evaluated using transmission electron microscopy. Serum was assayed for testosterone, luteinising hormone, follicle stimulating hormone and testicular tissue for malondialdehyde and glutathione. Ultrastructure of basement membrane (Bm), mitochondria and spermatocytes was normal in the control group. HAART-treated group showed significant increase (p < .01) in Bm thickness with significant decrease in Leydig cell nuclear diameter (p < .05) and volume (p < .01) when compared with control group. Mitochondrial cristae appear collapsed, and Sertoli cells showed cytoplasmic vacuolations. HAART+VCO group showed improved ultrastructural details in Bm, and Sertoli cell and Leydig cells show abundant lipid droplets. Virgin coconut oil-treated group showed thinning of Bm with otherwise normal ultrastructural features of organelles. HAART-treated group showed significant increase (p < .01) in testosterone levels. There was no significant effect on malondialdehyde and glutathione levels. Virgin coconut oil improved testicular morphology and reversed HAART-induced ultrastructural alterations. Further studies on putative mechanism are required.

Phytoecdysteroids from Ajuga iva act as potential antidiabetic agent against alloxan-induced diabetic male albino rats. Biomed Pharmacother 2017; 96:480-488. [PMID: 29031208 DOI: 10.1016/j.biopha.2017.10.029] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2017] [Revised: 10/03/2017] [Accepted: 10/06/2017] [Indexed: 02/04/2023] Open
Abstract
The present study investigated the protective effect of phytoecdysteroids extracted from the Ajuga iva plant on body weight changes, blood glucose, insulin total protein, blood urea nitrogen (BUN), creatinine, triglycerides (TG), cholesterol, lipid peroxidation, antioxidant enzymes, pancreatic histopathology and hexokinase-I expression in the alloxan-induced diabetic rats. Experimental diabetes was induced following 15day intraperitoneal administration of alloxan. The rats were divided into four groups. Group I served as a sham group, and group II served as the diabetic control. Group III served as a treatment for phytoecdysteroids (10mg/kg), and group IV served as a treatment for phytoecdysteroids (20mg/kg). Phytoecdysteroids restored body weight loss to its antihyperglycemic effect. Blood glucose was reduced 19.2 and 52.9% in group III and IV respectively. Blood insulin (54.9 and 105.88%) and total protein (25 and 72.2%) was increased in group III and IV respectively. BUN, creatinine, TG, cholesterol and lipid peroxidation was significantly reduced following treatment. Catalase, superoxide dismutase (SOD), and glutathione peroxidase activity were significantly increased following treatment. Islet β-cells are lost in alloxan-induced diabetic rats. Regeneration of islets and reduced atrophy of acinar cells were noted. The number of insulin-secreting cells was tremendously reduced in alloxan-induced diabetic rats. Insulin-secreting cells were increased 48 and 61% in group III and IV respectively. Hexokinase-I mRNA (28.3 & 93.5%) and protein (27.9 and 55.3%) expression were significantly increased following treatment. Taking all these data together, it is suggested that the phytoecdysteroid could be a potential therapeutic agent against experimental diabetes.

Abstract
OBJECTIVE To assess the modulatory impact of alcoholic extract of fruit of Mengkudu (AEFM, Morinda citrifolia L., Rubiaceae) on renal oxido-lipidemic stress in hypercholesterolemic albino rats. METHODS Twenty-four male albino rats were randomly divided into four groups with six rats in each group: group I as control, group II fed with hypercholesterolemic diet (HCD) for 45 days (4% cholesterol and 1% cholic acid), Group III rats fed with HCD for 45 days + AEFM (300 mg/kg body weight/day orally) for last 30 days and group IV normal rats fed AEFM alone. The blood was collected using ethylenediamine tetraacetic acid (EDTA) as an anticoagulant for various biochemical analysis, and excision of kidney was done for histological analysis. RESULTS The levels of total cholesterol (TC), triacylglycerol (TG), phospholipids (PLs), renal functional parameters and lipid peroxidation products were markedly mitigated in AEFM treated hypercholesterolemic rats (group III) compared to group I (P<0.01). Activities of both enzymic and non-enzymic free radical scavenging factors were significantly increased in group III compared to group I (P<0.01). In group III the mRNA levels of interstitial endothelial nitric oxide synthase (eNOS) and inducible nitric oxide synthase (iNOS) genes were obviously up-regulated (P<0.01) and down-regulated in (P<0.05) compared with group I. Histomorphological observations also exhibited similar as in group III AEFM commendably protects the renal tissues compared with group I (P<0.01). CONCLUSION AEFM can act as nephroprotective agent by attenuating the renal oxidative stress, lipid levels as well as regulating NOS level and by this means protects the kidney in hypercholesterolemic induced nephropathy experimental rats.

Abstract
We report the first analysis in absolute, and in particular, concerning the phytochemical pattern, about an endemic Italian species, Ajuga tenorei C. Presl. The analysis, performed by means of techniques such as Column Chromatography and NMR spectroscopy and Mass spectrometry, led to the isolation and the identification of five compounds namely verbascoside (1), echinacoside (2), ajugoside (3), harpagide (4) and 8-O-acetylharpagide (5). The presence of these compounds is important from both chemotaxonomic and ethno-pharmacological point of view. For what concerns the first point is confirmed the correct botanical classification of the species. The isolated compounds are also known to exert peculiar pharmacological activities and their presence may give a rationale to the historical medicinal properties associated to the Ajuga genus in general, since these plants have a long traditional use in many parts of the world. Such fact might suggest the use of also this species in this sense.

Abstract
Fish protein hydrolysate was prepared from muscle of small red scorpionfish (Scorpaena notata) by treatment with a protease from the fungus Penicillium digitatum. Protein hydrolysate was found to strongly inhibit the angiotensin I converting enzyme and exhibited high antioxidative activity through 1,1-diphenyl-2-picrylhydrazyl free radical scavenging assay. After ultrafiltration, peptides were isolated by a two-step procedure: size exclusion chromatography on a Toyopearl HW-40 followed by reversed-phase high-performance liquid chromatography with a high purification yield of 2.5 mg of peptide per gram of initial protein. Two major peptides were then identified by nanoscale liquid chromatography coupled to tandem mass spectrometry (nano-LC-MS/MS), corresponding to the following sequences: Leu-Val-Thr-Gly-Asp-Asp-Lys-Thr-Asn-Leu-Lys (1,204.665 Da) and Asp-Thr-Gly-Ser-Asp-Lys-Lys-Gln-Leu (992.511 Da). These peptides, mainly composed of hydrophilic amino acids, showed high antioxidative and angiotensin I converting enzyme inhibitory activities. These data suggest that the two novel peptides isolated from the muscle hydrolysate of small red scorpionfish can be a beneficial ingredient for functional foods or pharmaceuticals against hypertension and oxidative stress.

Abstract
PURPOSE Regular training is suggested to offer a host of benefits especially on cardiovascular system. In addition, medicinal plants can attenuate oxidative stress-mediated damages induced by stressor insults. In this study, we investigated the concomitant effect of cinnamon extract and long-term aerobic training on cardiac function, biochemical alterations and lipid profile following exhaustive exercise. METHODS Male Wistar rats (250-300 g) were divided into five groups depending on receiving regular training, cinnamon bark extraction, none or both of them, and then encountered with an exhausted exercise in last session. An 8-week endurance training program was designed with a progressive increase in training speed and time. Myocardial hemodynamics was monitored using a balloon-tipped catheter inserted into left ventricles. Blood samples were collected for analyzing biochemical markers, lipid profiles and lipid-peroxidation marker, malondealdehyde (MDA). RESULTS Trained animals showed an enhanced cardiac force and contractility similar to cinnamon-treated rats. Co-application of regular training and cinnamon had additive effect in cardiac hemodynamic (P<0.05). Both regular training and supplementation with cinnamon significantly decreased serum levels of total cholesterol, low-density lipoprotein (LDL), and increased high-density lipoprotein (HDL) level and HDL/LDL ratio as compared to control group (P<0.01). Furthermore, pre-treatment with cinnamon extract and/or regular training significantly reduced MDA level elevation induced by exhausted exercise (P<0.01). CONCLUSION Long-term treatment of rats with cinnamon and regular training improved cardiac hemodynamic through an additive effect. The positive effects of cinnamon and regular training on cardiac function were associated with a reduced serum MDA level and an improved blood lipid profile.

Abstract
CONTEXT Bacopa monniera L. (Scrophulariaceae) is used as a traditional medicine in India for various ailments such as epilepsy, mental disorders, and also as a cardio-tonic. However, its nephroprotective role is still unknown. OBJECTIVE The present study assesses the modulatory impact of the alcoholic (ethanol) extract of Bacopa monniera (AEBM) on renal oxido-lipidemic stress in hypercholesterolemic rats. MATERIALS AND METHODS B. monniera (1 kg) was extracted with 90% ethanol, filtered, and dried (52 g). Group-I rats as control, Group-II rats fed with a hypercholesterolemic diet (HCD) for 45 d [4% cholesterol and 1% cholic acid], Group-III rats fed with HCD for 45 d + AEBM (40 mg/kg, body weight) for last 30 d, and Group-IV AEBM alone rats. Blood and kidney were removed to analyze lipid, antioxidant status, and histological analysis. RESULT The levels of total cholesterol (TC), triacylglycerol (TG), phospholipids (PLs), renal functional parameters (urea, creatinine, and uric acid), and lipid peroxidation (LPO) products were significantly attenuated (p < 0.01) in AEBM-treated hypercholesterolemic rats. Activities of both enzymic (superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione-S-transferase (GST), and glutathione reductase (GR)) and non-enzymic antioxidant (GSH, Vit-C, and Vit-E) were significantly increased (p < 0.01), on supplementation with AEBM. Administration with AEBM the mRNA levels of eNOS and iNOS genes was significantly up-regulated and down-regulated (p < 0.01). Histomorphological observations also evidenced that AEBM effectively protects the kidney from hypercholesterolemia-mediated oxido-lipidemic damage. DISCUSSION AND CONCLUSION From this study, we hypothesized that AEBM can act as renoprotective agent by attenuating the renal oxido-lipidemic stress via regulating NOS level and thereby protects the nephron in hypercholesterolemic rats.

Abstract
Plant species have long been regarded as possessing the principal ingredients used in widely disseminated ethnomedical practices. Different surveys showed that medicinal plant species used by the inhabitants of Jordan for the traditional treatment of diabetes are inadequately screened for their therapeutic/preventive potential and phytochemical findings. In this review, traditional herbal medicine pursued indigenously with its methods of preparation and its active constituents are listed. Studies of random screening for selective antidiabetic bioactivity and plausible mechanisms of action of local species, domesticated greens, or wild plants are briefly discussed. Recommended future directives incurring the design and conduct of comprehensive trials are pointed out to validate the usefulness of these active plants or bioactive secondary metabolites either alone or in combination with existing conventional therapies.

Phenolic compounds from Rosemary (Rosmarinus officinalis L.) attenuate oxidative stress and reduce blood cholesterol concentrations in diet-induced hypercholesterolemic rats. Nutr Metab (Lond) 2013; 10:19.

Abstract
Background Phenolic compounds combine antioxidant and hypocholesterolemic activities and, consequently, are expected to prevent or minimize cardiometabolic risk. Methods To evaluate the effect of an aqueous extract (AQ) and non-esterified phenolic fraction (NEPF) from rosemary on oxidative stress in diet-induced hypercholesterolemia, 48 male 4-week old Wistar rats were divided into 6 groups: 1 chow diet group (C) and 5 hypercholesterolemic diet groups, with 1 receiving water (HC), 2 receiving AQ at concentrations of 7 and 140 mg/kg body weight (AQ70 and AQ140, respectively), and 2 receiving NEPF at concentrations of 7 and 14 mg/kg body weight (NEPF7 and NEPF14, respectively) by gavage for 4 weeks. Results In vitro, both AQ and NEPF had remarkable antioxidant activity in the 2,2-diphenyl-1-picrylhydrazyl (DPPH●) assay, which was similar to BHT. In vivo, the group that received AQ at 70 mg/kg body weight had lower serum total cholesterol (−39.8%), non-HDL-c (−44.4%) and thiobarbituric acid reactive substance (TBARS) levels (−37.7%) compared with the HC group. NEPF (7 and 14 mg/kg) reduced the tissue TBARS levels and increased the activity of tissular antioxidant enzymes (superoxide dismutase, catalase and glutathione peroxidase). Neither AQ nor NEPF was able to ameliorate the alterations in the hypercholesterolemic diet-induced fatty acid composition in the liver. Conclusions These data suggest that phenolic compounds from rosemary ameliorate the antioxidant defense in different tissues and attenuate oxidative stress in diet-induced hypercholesterolemic rats, whereas the serum lipid profile was improved only in rats that received the aqueous extract.

Abstract
The purpose of this study was to investigate the possible antioxidant effect of an aqueous extract of Ajuga iva (Ai) in streptozotocin (STZ)-induced diabetic rats. Twelve diabetic rats were divided into two groups fed a casein diet supplemented or not with Ai (0.5%), for 4 weeks. In vitro, the Ai extract possessed a very high antioxidant effect (1 mg/ml was similar to those of trolox 300 mmol/l). The results indicated that plasma thiobarbituric acid reactive substances (TBARS) values were reduced by 41% in Ai-treated compared with untreated diabetic rats. TBARS concentrations were lower 1.5-fold in liver, 1.8-fold in heart, 1.9-fold in muscle and 2.1-fold in brain in Ai-treated than untreated group. In erythrocytes, Ai treatment increased significantly the activities of glutathione peroxidase (GSH-Px) (+25%) and glutathione reductase (GSSH-Red) (+22%). Superoxide dismutase activity was increased in muscle (+22%), while GSH-Px activity was significantly higher in liver (+28%), heart (+40%) and kidney (+45%) in Ai-treated compared with untreated group. Liver and muscle GSSH-Red activity was, respectively, 1.6- and 1.5-fold higher in Ai-treated than untreated diabetic group. Catalase activity was significantly increased in heart (+36%) and brain (+32%) in Ai-treated than untreated group. Ai treatment decreased plasma nitric oxide (-33%), carbonyls (-44%) and carotenoids (-68%) concentrations. In conclusion, this study indicates that Ajuga iva aqueous extract improves the antioxidant status by reducing lipid peroxidation and enhancing the antioxidant enzymes activities in plasma, erythrocytes and tissues of diabetic rats.

Abstract
The aim of the study was to investigate the effect of aqueous extract of Ajuga iva (Ai) on serum and tissues lipid peroxidation as well as antioxidant enzymes activities in red blood cells (RBC) and tissues, in high hypercholesterolemic rats (HC). Male Wistar rats (n=12) were fed on 1% cholesterol-enriched diet for 15d. After this adaptation phase, hypercholesterolemic rats (total cholesterol=6.5+/-0.6mol/l) were divided into two groups fed the same diet and treated or not with Ai for 15d. Thiobarbituric acid reactive substances (TBARS) concentrations in serum, LDL-HDL(1), HDL(2) and HDL(3) were respectively, 5-, 7.8-, 2.3- and 5-fold lower in Ai treated than untreated hypercholesterolemic groups. TBARS concentrations were 1.4-fold lower in heart and 2.8-fold higher in kidney in Ai-HC treated than untreated HC group. Superoxide dismutase activity was respectively, 1.2- and 1.4-fold higher in RBC and muscle in Ai treated than untreated group. In RBC, Ajuga iva treatment enhanced glutathione peroxidase (GSH-Px) (+9%) and glutathione reductase (GSSH-Red) (+12%) in Ai-HC treated than untreated HC group. GSSH-Red activity was 1.4- and 1.5-fold higher in adipose tissue and heart, respectively and 3.7-fold lower in kidney in Ai treated than untreated group. Liver catalase activity was 1.6-fold higher in Ai treated than untreated group. Adipose tissue and muscle total glutathione content represented in Ai treated group 35% and 36% of the value noted in untreated group. Nitric oxide values of liver, adipose tissue and heart were 3.3-, 2.5- and 3.4-fold higher in Ai-HC than HC group. Ajuga iva treatment enhanced alpha-tocopherol contents (+25%) in Ai treated than untreated group. In conclusion, Ajuga iva treatment is more effective to improve the antioxidant capacity of RBC than that of tissues. Indeed, Ai is able to reduce the oxidative stress in hypercholesterolemic rats by increasing the antioxidant enzymes activity.

Abstract
Antioxidants are emerging as prophylactic and therapeutic agents for various diseases. However, little is known about the antioxidant property of the extract from Flos Lonicerae, a medically useful traditional Chinese medicine herb. Here the antioxidant capacity of water, methanolic and 70% ethanolic extracts prepared from Flos Lonicerae to scavenge DPPH radical and reduce Fe(3+) to Fe(2+) is evaluated. Chlorogenic acid, a major component of Flos Lonicerae, is identified and further purified from 70% ethanolic extract with HPLC and its antioxidant capacity is also characterized. The content of total phenolic compounds and chlorogenic acid in Flos Lonicerae is determined. The present results demonstrate that all Flos Lonicerae extracts examined here exhibit antioxidant activity and chlorogenic acid is a major contributor to this activity, which implicates that the Flos Lonicerae extract may serve as potential source of natural antioxidants for treatment of some diseases.

Abstract
In the current study, the effect of Ajuga iva extract on blood glucose, lipid profile, hepatic and renal toxicity and antioxidant enzyme activities in alloxan-induced diabetic rats was investigated. Diabetes was confirmed by measuring the glucoserua concentration 15 days after alloxan administration. Ajuga iva extract was administrated orally 3 weeks after alloxan injection. Our results investigate that Ajuga iva extract supplementation increased the levels of both enzymatic antioxidant (superoxide dismutase, catalase and glutathione peroxidase) and metals antioxidants (iron, copper, magnesium, calcium) and decreased lipid peroxidation level (TBARs). Besides Ajuga iva ameliorated diabetes provoked hepatic and renal toxicity appeared by a lower level in total and direct bilirubin, urea, creatinine, triglyceride (TG), cholesterol and a higher level in HDL-cholesterol. Besides, the activities of phosphatase alkalines (PAL), aspartate and lactate transaminase (AST & ALT) were decreased. The benefices effects of phytoecdysteroids of Ajuga iva confirmed by histological observation in pancreatic tissues. In conclusion, Ajuga iva phytoecdysteroids supplements seem to be beneficial for correcting the hyperglycemia and preventing diabetic complications in liver, pancreas and kidneys.
