In vivo evaluation of antivenom activity of Adenocarpus anagyrifolius methanolic extract against Hottentotta gentili scorpion venom

The antivenom property of the methanolic extract of aerial parts of Adenocarpus anagyrifolius against Hottentotta gentili was evaluated by gavage (100, 150, and 200 mg/kg) after subcutaneous injection of LD99 of H. gentili venom. The results showed a very efficient response with a survival of the mice even after 24 h, while the injection with LD50 and a dose of 200 mg/kg showed a restoration of the lesions in different tissues and a significant decrease of the biochemical markers. The high antioxidant efficiency with the presence of active metabolites may explain the potential of A. anagyrifolius as natural product drug candidate.

Cocculus hirsutus-Derived Phytopharmaceutical Drug Has Potent Anti-dengue Activity.

Dengue is a serious public health concern worldwide, with ∼3 billion people at risk of contracting dengue virus (DENV) infections, with some suffering severe consequences of disease and leading to death. Currently, there is no broad use vaccine or drug available for the prevention or treatment of dengue, which leaves only anti-mosquito strategies to combat the dengue menace. The present study is an extension of our earlier study aimed at determining the in vitro and in vivo protective effects of a plant-derived phytopharmaceutical drug for the treatment of dengue. In our previous report, we had identified a methanolic extract of aerial parts of Cissampelos pareira to exhibit in vitro and in vivo anti-dengue activity against all the four DENV serotypes. The dried aerial parts of C. pareira supplied by local vendors were often found to be mixed with aerial parts of another plant of the same Menispermaceae family, Cocculus hirsutus, which shares common homology with C. pareira. In the current study, we have found C. hirsutus to have more potent anti-dengue activity as compared with C. pareira. The stem part of C. hirsutus was found to be more potent (∼25 times) than the aerial part (stem and leaf) irrespective of the extraction solvent used, viz., denatured spirit, hydro-alcohol (50:50), and aqueous. Moreover, the anti-dengue activity of stem extract in all the solvents was comparable. Hence, an aqueous extract of the stem of C. hirsutus (AQCH) was selected due to greater regulatory compliance. Five chemical markers, viz., Sinococuline, 20-Hydroxyecdysone, Makisterone-A, Magnoflorine, and Coniferyl alcohol, were identified in fingerprinting analysis. In a test of primary dengue infection in the AG129 mice model, AQCH extract at 25 mg/kg body weight exhibited protection when administered four and three times a day. The AQCH was also protective in the secondary DENV-infected AG129 mice model at 25 mg/kg/dose when administered four and three times a day. Additionally, the AQCH extract reduced serum viremia and small intestinal pathologies, viz., viral load, pro-inflammatory cytokines, and vascular leakage. Based on these findings, we have undertaken the potential preclinical development of C. hirsutus-based phytopharmaceutical, which could be studied further for its clinical development for treating dengue.

Isolation and elucidation of two isoflavonoids from an American Indian plant, Amorpha canescens Pursh, using Magnetic Microbead Affinity Selection Screening (MagMASS) for estrogen receptor alpha ligands.

A new isoflavonoid, xanthocerin J, along with previously described xanthocerin A, were isolated from a methanol extract of aerial parts of a traditional American Indian herb, Amorpha canescens Pursh (Asteraceae). The structures of these compounds were characterized using mass spectrometry and NMR based on an isolation protocol using magnetic microbead affinity selection screening (MagMASS) for ligands to the estrogen receptor alpha (ERα). These compounds bound to ERα from an active fraction that exhibited dose-dependent antiestrogenic activity in the in vitro Ishikawa assay. However, these compounds did not exhibit antiestrogenic activity in the cell-based Ishikawa assay. Xanthocerin A and J may exhibit synergistic or additive activity with other compounds found in A. canescens which needs further exploration. This work highlights the potential of A. canescens as a prospect for the future discovery of compounds for women's health related to estrogen pathways.

Phytochemical Screening and Antimicrobial Activity of Various Extracts of Aerial Parts of Rhanterium epapposum

Rhanterium epapposum, native to the Arabian Peninsula, is traditionally used to cure skin infections. The objective is to screen the phytochemical content and antimicrobial activity of aqueous, methanol and 80% methanol extracts of aerial parts of R. epapposum. The phytochemical screening of aqueous, methanolic, and 80% methanol extracts of R. epapposum was conducted using gas chromatographymass spectrometry. The antimicrobial activities of the extracts were assessed by well diffusion and microdilution methods. Qualitative phytochemical analysis revealed the presence of 2-methoxy-4-vinylphenol in all three extracts, whereas ethanol, 2-methoxy-, acetate; n-hexadecanoic acid; and 2,3-butanediol are present in higher amount exclusively in the methanol, 80% methanol and aqueous extracts of the aerial parts of R. epapposum, respectively. The highest antibacterial activity was shown by the aqueous extract S. aureus, P. aeruginosa, E. cloacae, and K. pneumoniae, methanolic extract against S. aureus, methicillin-resistant S. aureus, and E. coli, and 80% methanol extract against S. epidermidis, and S. paucimobilis. Interestingly, 80% methanol extracts showed the highest antifungal activity against C. albicans, C. guillermondii, C. vaginalis, C. utilis, and C. tropicalis. The aerial parts of R. epapposum showed broad-spread antimicrobial activity against bacteria and fungi. Especially, the 80% methanol extract showed potent antifungal activity against all the tested fungal strains.

Evaluation of extracts of wild Cannabis sativa L. for genotoxicity and phytochemical composition

Cannabis sativa L. is used as medicine and narcotic in Lesotho. Phytochemical composition and total phenolics content (TPC) for hexane, chloroform, ethyl acetate and methanol extracts of aerial parts of C. sativa were determined. Ethyl acetate extract (0.1875, 0.375 and 0.75 mg mL-1) and methanol extract (0.75, 1.5 and 3.0 mg mL-1) were evaluated for cytotoxicity, genotoxicity and modulation of cyclophosphamide (CP, 1.25 mg mL-1)- and ethylmethane sulphonate (EMS, 0.25 mg mL-1)-induced genotoxicity using Allium cepa root meristem assay. CP or EMS did not reduce mitotic index (MI) of cells, hence not cytotoxic when compared with negative control using the t-test (p>0.05), but genotoxic. Both extracts were genotoxic with methanol extract also being cytotoxic. Genotoxicity was the number of aberrant cells per 100 mitotic cells. Modulatory effect (ME) was obtained by comparing mutagen-induced genotoxicity with mixture-induced genotoxicity and expressed as the number of units of mutagen-induced genotoxicity that equalled the mixture-induced genotoxicity. ME was either positive or negative and significant only if ME = ≥ 2. Both extracts were genotoxic with methanol extract also being cytotoxic. Aberrations observed were sticky chromosomes, c-metaphase, anaphase and telophase bridges, chromosome fragments and laggards. Mixture of methanol extract with CP or EMS was more genotoxic (+ME range = 1.61-11.89) than the mutagen or extract alone which suggested synergistic interaction. Mixture of ethyl acetate extract with CP induced insignificant +ME. Mixture of ethylacetate extract with EMS was significantly more genotoxic (+ME = 2.20) than EMS only at high extract concentration. The methanol and ethylacetate extracts of C. sativa were not anti-genotoxic to CP- or EMS- induced genotoxicity. TPCs for hexane, chloroform, ethyl acetate and methanol extracts were 39831.46, 2544.94, 2438.20 and 56601.12 mg GAE/gram dry weight respectively. The differences in the cytotoxicity and MEs of the extracts were attributed to differences in phytochemical composition of extracts.

Essential oil composition, phenolics and antioxidant activities of Valeriana jatamansi at different phenological stages

Valeriana jatamansi Jones is an important herbaceous plant of the Caprifoliaceae family used for the treatment of insomnia and stress-related disorders, due to its sedative and anxiolytic properties. In the present study, aerial parts and roots of the species collected in three phenological stages (pre-flowering, flowering and post-flowering) from three natural populations located at an altitudinal gradient were analysed for essential oil composition, phenolics, and antioxidant activity. Essential oil obtained from rhizomes exhibited qualitative and qualitative variations in growth phenophases along the altitudes. Methanolic extracts of aerial parts and roots revealed that the majority of phenolic compounds such as, gallic acid, catechin, chlorogenic acid, hydroxybenzoic acid, caffeic acid and p-coumaric acid, varied largely among different phenological stages along the altitudes. Pre-flowering stage was found to possess maximum concentration of phenolics, flavonoids and higher antioxidant activity in the aerial parts and roots. Findings from this study highlighted that the pre-flowering stage is the most suitable time for harvesting to obtain maximum phytochemicals and antioxidant activity. Further, high level of few phenolics in per-flowering stage at high altitude, suggested the requirement of compound-specific agro-climatic techniques to obtain commercial benefits from the cultivation of V. jatamansi.
