Chang HC, Lien JC, Hsueh MC, Wu CR. Exploring the Neuroprotective Potential of Desmodium Species: Insights into Radical Scavenging Capacity and Mechanisms against 6-OHDA-Induced Neurotoxicity. PLANTS (BASEL, SWITZERLAND) 2024; 13:1742. [PMID: 38999581 PMCID: PMC11244519 DOI: 10.3390/plants13131742] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/16/2024] [Revised: 06/20/2024] [Accepted: 06/21/2024] [Indexed: 07/14/2024]
Abstract
In this study, we collected seven prevalent Taiwanese Desmodium plants, including three species with synonymous characteristics, in order to assess their antioxidant phytoconstituents and radical scavenging capacities. Additionally, we compared their inhibitory activities on monoamine oxidase (MAO) and 6-hydroxydopamine (6-OHDA) auto-oxidation. Subsequently, we evaluated the neuroprotective potential of D. pulchellum on 6-OHDA-induced nerve damage in SH-SY5Y cells and delved into the underlying neuroprotective mechanisms. Among the seven Desmodium species, D. pulchellum exhibited the most robust ABTS radical scavenging capacity and relative reducing power; correspondingly, it had the highest total phenolic and phenylpropanoid contents. Meanwhile, D. motorium showcased the best hydrogen peroxide scavenging capacity and, notably, D. sequax demonstrated remarkable prowess in DPPH radical and superoxide scavenging capacity, along with selective inhibitory activity against MAO-B. Of the aforementioned species, D. pulchellum emerged as the frontrunner in inhibiting 6-OHDA auto-oxidation and conferring neuroprotection against 6-OHDA-induced neuronal damage in the SH-SY5Y cells. Furthermore, D. pulchellum effectively mitigated the increase in intracellular ROS and MDA levels through restoring the activities of the intracellular antioxidant defense system. Therefore, we suggest that D. pulchellum possesses neuroprotective effects against 6-OHDA-induced neurotoxicity due to the radical scavenging capacity of its antioxidant phytoconstituents and its ability to restore intracellular antioxidant activities.

Abstract
Secondary metabolites are an important part to play a major role in society and it was isolated from plant flavonoids and useful in the treatment of various kinds of diseases in the human race. They are widely used as food and nutrition supplements as well as antioxidants. Traditionally, the Desmodium species are an important tool for the secondary metabolites to treat various diseases. Desmodium triquetrum (Fabaceae) one of the Indian medicinal plants is widely used in the treatment of asthma and inflammation. Three flavonoids isolated from Desmodium triquetrum Linn namely Baicalein, Naringin and Neohesperidin are useful as antioxidants, food and nutrition supplements, that help the body to function efficiently while protecting it against toxins as well stressors. The role of flavonoids may be due to the presence of the phenolic compound. Similarly, the flavonoids such as gangetin, gangetinin, desmocarpin and desmodin isolated from the species Desmodium gangeticum are responsible for antileishmanial, antioxidant, anti-arthritic, and immunomodulatory activities. Additionally, isolated flavanoids from the species Desmodium triflorum show antibacterial, antiepileptic, antifungal, and radioprotective activities. So, the aim of the present study, based on the literature miming from the desmodium species is to acknowledge the importance of flavonoids in human health as dietary food supplements and therapeutic uses.

[PMID: 37836717 PMCID: PMC10574196 DOI: 10.3390/molecules28196875] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 09/11/2023] [Accepted: 09/27/2023] [Indexed: 10/15/2023] Open
Abstract
Ethnomedicinal plants are important sources of drug candidates, and many of these plants, especially in the Western Ghats, are underexplored. Humboldtia, a genus within the Fabaceae family, thrives in the biodiversity of the Western Ghats, Kerala, India, and holds significant ethnobotanical importance. However, many Humboldtia species remain understudied in terms of their biological efficacy, while some lack scientific validation for their traditional uses. However, Humboldtia sanjappae, an underexplored plant, was investigated for the phytochemical composition of the plant, and its antioxidant, enzyme-inhibitory, anti-inflammatory, and antibacterial activities were assessed. The LC-MS analysis indicated the presence of several bioactive substances, such as Naringenin, Luteolin, and Pomiferin. The results revealed that the ethanol extract of H. sanjappae exhibited significant in vitro DPPH scavenging activity (6.53 ± 1.49 µg/mL). Additionally, it demonstrated noteworthy FRAP (Ferric Reducing Antioxidant Power) activity (8.46 ± 1.38 µg/mL). Moreover, the ethanol extract of H. sanjappae exhibited notable efficacy in inhibiting the activities of α-amylase (47.60 ± 0.19µg/mL) and β-glucosidase (32.09 ± 0.54 µg/mL). The pre-treatment with the extract decreased the LPS-stimulated release of cytokines in the Raw 264.7 macrophages, demonstrating the anti-inflammatory potential. Further, the antibacterial properties were also evident in both Gram-positive and Gram-negative bacteria. The observed high zone of inhibition in the disc diffusion assay and MIC values were also promising. H. sanjappae displays significant anti-inflammatory, antioxidant, antidiabetic, and antibacterial properties, likely attributable to its rich composition of various biological compounds such as Naringenin, Luteolin, Epicatechin, Maritemin, and Pomiferin. Serving as a promising reservoir of these beneficial molecules, the potential of H. sanjappae as a valuable source for bioactive ingredients within the realms of nutraceutical and pharmaceutical industries is underscored, showcasing its potential for diverse applications.

Abstract
Desmodium styracifolium is a medicinal plant from the Desmodieae tribe, also known as Grona styracifolia. Its role in the treatment of urolithiasis, urinary infections, and cholelithiasis has previously been widely documented. The complete chloroplast genome sequence of D. Styracifolium is 149,155 bp in length with a GC content of 35.2%. It is composed of a large single copy (LSC) of 82,476 bp and a small single copy (SSC) of 18,439 bp, which are separated by a pair of inverted repeats (IR) of 24,120 bp each and has 128 genes. We performed a comparative analysis of the D. styracifolium cpDNA with the genome of previously investigated members of the Sesamoidea tribe and on the outgroup from its Phaseolinae sister tribe. The size of all seven cpDNAs ranged from 148,814 bp to 151,217 bp in length due to the contraction and expansion of the IR/SC boundaries. The gene orientation of the SSC region in D. styracifolium was inverted in comparison with the other six studied species. Furthermore, the sequence divergence of the IR regions was significantly lower than that of the LSC and the SSC, and five highly divergent regions, trnL-UAA-trnT-UGU, psaJ-ycf4, psbE-petL, rpl36-rps8, and rpl32-trnL-UGA, were identified that could be used as valuable molecular markers in future taxonomic studies and phylogenetic constructions.

Abstract
Abstract
Background
The majority of epidemic Vibrio cholerae strains have become resistant to multiple antimicrobial agents for many reasons, including mutations, horizontal gene transfers, etc. Therefore, secondary means of treatment are needed to overcome this impediment in combating cholera. Desmodium triflorum (L.) and Terminalia citrina (Roxb.) are extensively used in traditional medicine. Therefore, the present study aims to evaluate the antibacterial activity of methanolic and ethanolic extracts of Desmodium triflorum (L.) whole plant and Terminalia citrina (Roxb.) fruits against V. cholerae isolates.
Methods
Initially, different extracts of both plant materials were subjected to qualitative phytochemical screening. Anti-V. cholerae activities were assessed by performing MIC (minimum inhibitory concentration) test using disc diffusion method with different concentrations (1.25, 2.50, 8.00, 10.00, 12.50, 15.00 mg/ml) where standard discs of gentamycin and meropenem (10 μg/disc) were used. Further, Brine shrimp lethality bioassay was done to evaluate the extracts’ cytotoxic activities using different concentrations (800, 400, 200, 100, 50, 25, 12.5, 6.25 μg/ml) against vincristine sulphate.
Results
The preliminary screening confirms the presence of convenient phytochemical constituents like flavonoids, alkaloids, glycosides, tannins, etc., and are liable for the emergence of the antibacterial activities in different strains. The minimum inhibitory concentrations of both methanolic and ethanolic extracts of Terminalia citrina (fruits) and Desmodium triflorum (L.) (whole plant) were found to be 2.50 mg/ml and 5 mg/ml, respectively. Moreover, 100% mortality was observed only in ethanolic extract of Terminalia citrina fruits at the highest concentration (800 μg/ml). In comparison, the rest of the test extracts showed less than 90% mortality at the highest concentration (800 μg/ml).
Conclusions
Both plants possess significant phytoconstituents and showed appreciable anti-V. cholerae activities with mild toxicity. Hence, Desmodium triflorum (L.) whole plant and Terminalia citrina (Roxb.) fruits may be recommended as potential phytotherapy against cholera disease.

Abstract
OBJECTIVE Polygonatum verticillatum (L.) All. (Ruscaceae), one of the Ashtawarga plants, is widely used for treatment of various ailments. The present study was undertaken to determine the phenolic composition, antioxidant, anti-inflammatory and anticancer activities of several extracts (petroleum ether, dichloromethane, chloroform, ethanol, and aqueous) from the rhizomes of the plant. METHODS Coarsely powdered dry rhizome was successively extracted with different solvents of increasing polarity (petroleum ether, dichloromethane, chloroform, ethanol and water). The phenolic compositions, in terms of total phenolic content (TPC), total flavonoid content (TFC) and total condensed tannin content (TTC), were evaluated with the Folin-Ciocalteu assay, aluminum chloride colorimetric assay and vanillin spectrophotometric assay, respectively. Total antioxidant capacity, 1,1-diphenyl-2-picrylhydrazyl and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) assays were used to assess the antioxidant potential of each extract. A protein denaturation model and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay were used to evaluate in vitro anti-inflammatory and anticancer activities, respectively. Gas chromatography-mass spectrometry (GC/MS) analysis was carried out to demonstrate various phytoconstituents in each extract. Correlation studies were also performed between phenolic composition (TPC, TFC and TTC) and different biological activities. RESULTS Ethanol extract showed maximum TPC (0.126 mg/g, gallic acid equivalent in dry sample), TFC (0.094 mg/g, rutin equivalent in dry sample) and TTC (29.32 mg/g, catechin equivalent in dry sample), as well as antioxidant and anti-inflammatory properties. Chloroform extract exhibited the strongest cytotoxicity against the human breast cancer cell line, MCF-7. GC/MS analysis revealed the presence of 90 different phytoconstituents among the extracts. Antioxidant and anti-inflammatory activities had a positive correlation with TPC, TFC and TTC. However, the anticancer activity showed a negative correlation with TPC, TFC and TTC. CONCLUSION From the present study, it can be concluded that P. verticillatum possessed remarkable antioxidant, anti-inflammatory, and anticancer activities, which could be due to different secondary metabolites of the plant. Phenolic compounds are likely responsible for antioxidant and anti-inflammatory activities. However, flavonoids and other compounds might contribute to the anticancer potential of the plant.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Weeds are plants grow naturally and are commonly seen. They are mostly used for feedstuff. However, their use as herbs for treating diseases, including gastrointestinal disorders, is rare. Therefore, the present study aimed to: (1) quantify the number of herbal weeds used for treating gastrointestinal disorders; (2) study local knowledge of weed utilization for treating gastrointestinal disorders in Songkhla and Krabi provinces; and (3) analyse quantitative data with the Informant Consensus Factor (ICF), Use Value (UV) and Fidelity Level (FL). MATERIALS AND METHODS The study was conducted from November 2014 to January 2016 through semi-structured interviews with 35 folk healers. The main questions were designed to obtain plant information, including the local name, method of use, preparation method and medicinal properties. The data were analysed by descriptive statistics, quantitative indexes (UV, ICF as well as FL) and interpretation. RESULTS A total of 49 species in 46 genera and 28 families were found. The most common use of weeds was as herbs (80%). The preferred part used was the whole plant (76.27%). The preferred methods of drug preparation and use were decoction and drink, respectively. The highest UV was found for Acmella oleracea (0.83). The highest FLs (100%) were found for 12 species, including Amaranthus spinosus, Amaranthus viridis, Alternanthera sessilis, Sauropus androgynus, Plantago major, and others. The highest ICF (0.93) was found for treating toothache. CONCLUSION Overall, there are reports on the pharmacological activity of 31 species of weeds and reports on toxicity for 20 species of weeds. Therefore, awareness of the use of herbs is necessary to ensure that they are used safely and that benefits arise from the therapy. This study showed that medicinal weeds are still popularly used by folk healers. The pharmacological properties were consistent with the local uses, which supported a preliminary indication that the weed plants were effective for treating gastrointestinal diseases.

Abstract
Lobelia chinensis Lour (LcL) is a popular herb that has been widely used as folk medicine in China for the treatment of fever, lung cancer, and inflammation for hundreds of years. Recently, several studies have shown that the anti-inflammatory properties were correlated with the inhibition of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) from the NF-κB pathway. The aim of this study was to evaluate the anti-oxidative and anti-inflammatory activities of L. chinensis. Both suppressive activities on LPS-induced nitric oxide production in RAW264.7 macrophages in vitro and the acute rat lung injury model in vivo were studied. The results showed that the methanol extract of LcL and its fractions within the range of 62.5–250 μg/mL did not induce cytotoxicity (p < 0.001). The ethyl acetate fraction of LcL showed better NO inhibition activity than other fractions. On the other hand, the Lc-EA (62.5, 125, 250 mg/kg) pretreated rats showed a decrease in the pro-inflammatory cytokines (TNF-α, IL-β, IL-6) and inhibited iNOS, COX-2 expression through the NF-κB pathway. These results suggested that L. chinensis exhibited an anti-inflammatory effect through the NF-κB pathways.

Abstract
Inflammation is related to several chronic diseases, including cancer and atherosclerosis. Taxillus sutchuenensis (Lecomte) Danser is a special folk medicinal plant in Taiwan. The aim of this study was to evaluate the antioxidant, anti-inflammatory, and antiproliferative activities of the aqueous-thanol extract from T. sutchuenensis (AETS) and its fractions. TEAC, DPPH radicals, total phenolic compounds, total flavonoid content, inhibition of NO production in LPS-induced RAW264.7 cells, and inhibition of cancer cell proliferation were tested. Among all fractions, the ethyl-acetate (EA) fraction showed the highest TEAC and DPPH radical scavenging activities. The EA fraction also had the highest polyphenol and flavonoid content. The EA fractions also decreased LPS-induced NO production and the expression of iNOS and COX-2 in RAW264.7 cells. The antiproliferative activities of the aqueous/ethanol extract and fractions were studied in vitro using A549 cells, and the results were consistent with their antioxidant capacities. EA fractions had the highest antiproliferative activity with an IC(50) of 454.38 ± 1.48 μg/ml. Quercetin also had antioxidant, anti-inflammatory, and antiproliferative activities. Quercetin might be an important bioactive compound in T. sutchuenensis. The experimental data indicated that T. sutchuenensis is a potent antioxidant medicinal plant, and such efficacy may be mainly attributed to its polyphenolic compounds.

Abstract
The genus Leonurus has long been recognized as a natural group, but its interspecific relationship has not yet been studied in the light of sequence data. The ITS regions and matK sequences of all subgenera of Leonurus in China were amplified, sequenced and investigated. Phylogenies generated by maximum parsimony and neighbor-joining methods and division of the genus into two major clades. The phylogenetic results indicated that L. chaituroides has the very close phylogenetic relationship with Subg. Cardiochilium and supported the notion that L. macranthus acts as the bridge between Subg. cardiochilium and Subg. Leonurus. According to the analysis of information given by ITS and matK sequences, we suggest that ITS sequences would be more suitable to serve as markers for authentication of Herba Leonuri than matK does.

Abstract
Oxidative stress and inflammation are related to several chronic diseases including cancer and atherosclerosis. Kalanchoe gracilis (L.) DC is a special folk medicinal plant in Taiwan. The aim of this study was to evaluate the antioxidant, anti-inflammatory and antiproliferative activities of the methanolic extract and fractions of the stem of K. gracilis. TEAC, total phenolic compound content, total flavonoid content, DPPH radical scavenging activity, reducing power, inhibition of NO production in LPS-induced RAW264.7 cells, and inhibition of cancer cell proliferation were analyzed. Among all fractions, the chloroform fraction showed the highest TEAC and DPPH radical scavenging activities. The chloroform fraction also had the highest content of polyphenols and flavonoids. Chloroform fractions also decreased LPS-induced NO production and expressions of iNOS and COX-2 in RAW264.7 cells. The antiproliferative activities of the methanolic extract and fractions were studied in vitro using HepG2 cells, and the results were consistent with their antioxidant capacities. Chloroform fractions had the highest antiproliferative activity with an IC(50) of 136.85 ± 2.32 μg/ml. Eupafolin also had good pharmacological activity in the antioxidant, anti-inflammation and antiproliferative. Eupafolin might be an important bioactive compound in the stem of K. gracilis. The above experimental data indicated that the stem of K. gracilis is a potent antioxidant medicinal plant, and such efficacy may be mainly attributed to its polyphenolic compounds.

[PMID: 22004895 DOI: 10.1016/j.jep.2011.09.053] [Citation(s) in RCA: 41] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/22/2011] [Revised: 09/29/2011] [Accepted: 09/29/2011] [Indexed: 05/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Plants of the genus Desmodium (Fabaceae), such as Desmodium styracifolium (Osbeck) Merr. and Desmodium gyrans (L. f.) DC., have a long history of medical use in Traditional Chinese Medicine to treat various ailments including rheumatism, pyrexia, dysentery, wounds, cough, malaria, hepatitis, hemoptysis, etc. In the theory of Traditional Chinese Medicine, most species have the effect of relieving internal heat or fever, neutralizing toxins, inhibiting pain, invigorating blood circulation, suppressing cough and alleviating dyspnea. MATERIALS AND METHODS A bibliographic investigation was accomplished by analyzing secondary sources including Chinese Herbal Classics, and worldwide accepted scientific databases (Pubmed, Scopus and Web of Science, SciFinder) were scrutinized for the available information on the ethnopharmacological uses in Chinese medicine, phytochemistry, pharmacology and toxicology of Desmodium species. RESULTS The genus Desmodium is a large member of the Papilionaceae (Fabaceae) family. It contains about 350 plant species used for both feeding stuffs and herbal medicines, of which only about 30 species have been phytochemically or pharmacologically investigated. Desmodium plant extracts, as well as the active principles, have been experimentally studied for their anti-inflammatory, cytotoxic, antidiabetic, antinephrolithic, antibacterial, and nootropic activities in vitro or in vivo. And so far, a total of 212 compounds have been isolated from 15 Desmodium species and characterized mainly as flavonoids and alkaloids, followed by terpenoids, steroids, phenols, phenylpropanoids, glycosides and a number of volatile oils. The remaining unrevealed species are recorded chiefly in Asia and Africa being used in empirical treatment for various diseases. CONCLUSIONS Desmodium species have long been used in TCM to treat various ailments. Available scientific references revealed that the traditional medical uses of some important Desmodium species in TCM have been evaluated by modern pharmacological studies. As literature demonstrated, flavonoids and alkaloids are perhaps responsible for most of the activities shown by the plants of this genus. Further studies are still required to reveal the structure-activity relationship of these active constituents.

Antioxidant activities of total phenols of Prunella vulgaris L. in vitro and in tumor-bearing mice. Molecules 2010; 15:9145-56. [PMID: 21150830 PMCID: PMC6259167 DOI: 10.3390/molecules15129145] [Citation(s) in RCA: 40] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2010] [Revised: 11/22/2010] [Accepted: 12/08/2010] [Indexed: 11/17/2022] Open
Abstract
Prunella vulgaris L. (PV, Labiatae) is known as a self-heal herb. The different extracts of dried spikes were studied for the best antioxidant active compounds. The 60% ethanol extract (P-60) showed strong antioxidant activity based on the results of 2,2'-azino-di(3-ethylbenzthiazoline-6-sulfonic acid (ABTS˙+), 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assay methods. High performance liquid chromatography (HPLC) and LC/MS analysis showed that the main active compounds in P-60 were phenols, such as caffeic acid, rosmarinic acid, rutin and quercetin. Total phenols were highly correlated with the antioxidant activity (R2=0.9988 in ABTS˙+; 0.6284 in DPPH and 0.9673 FRAP tests). P-60 could inhibit significantly the tumor growth in C57BL/6 mice. It can also been showed that increased superoxide dismutase (SOD) activity and decreased malondialdehyde (MDA) content in serum of tumor-bearing mice. These results suggested that P-60 extract had high antioxidant activity in vitro and in vivo and total phenols played an important role in antioxidant activity for inhibition of tumor growth.
