5DPPH antiradical scavenging, anthelmintic and phytochemical studies of Cissus poulnea rhizomes显示文摘Objective: To investigate the phytochemical constituents, antioxidant and anthelmintic activities of the crude methanol extract of Cissus populnea(C. populnea) rhizomes. Methods: Phytochemical screening was performed using standard protocols, and column chromatography of silica gel was used for the compounds isolation. DPPH antiradical scavenging assay was performed in order to evaluate the antioxidant activity. Total phenolic content was evaluated using the Folin–Ciocalteu assay. The anthelmintic activity was screened on the bovine adult male forms of parasitic nematode Onchocerca ochengi, by the in vitro evaluation of the inhibition of adult worm motility and mortality. Worms were incubated in the presence of different concentrations of the plant extract and effects on survival were monitored after 24 and 48 h. Results: The preliminary phytochemical screening revealed the presence of phenolic compounds, saponins, steroids, tannins, and terpenoids. Bergenin and a mixture of phytosterol, β-sitosterol and stigmasterol were isolated from this extract and were identified by nuclear magnetic resonance, mass spectrometry and by comparison with published data. The crude methanol extract of C. populnea rhizomes showed a strong DPPH antiradical activity with a good amount of total phenolic content((20.69±2.13) g gallic acid equivalent/100 g of extract) and significant anthelmintic activity comparable to the standard drug ivermectin. Bergenin was found to be inactive even after 72 h of incubation. Conclusions: This study constitutes the first report on the anthelmintic activity of this plant and supports the traditional use of C. populnea as a natural antioxidant and anthelmintic.Jean Noel Nyemb Roland Ndoubalem Emmanuel Talla Alembert Tiabou Tchinda Dieudonne Ndjonka Celine Henoumont Sophie Laurent Joseph Tanyi Mbafor 2018Asian Pacific Journal of Tropical Medicine2018,11,4:1

17Improved germination of threatened medicinal Prunus africana for better domestication: effects of temperature, growth regulators and salts显示文摘Prunus africana is an endangered medicinal species and has been classified as a priority for domestication in Cameroon.However,the seeds rapidly lose their viability during storage at room temperature after 2–3 months.This study aimed to improve seed germination of P.africana by germinating at different temperatures(4℃,28℃)using different concentrations of growth stimulators(sodium nitrate and gibberellic acid)and different concentrations of salts.P.africana seeds had 91.7%germination at 4C after 1 month of storage.Growth regulators considerably influenced germination after 6 months and reached 66.0%with 10 mM gibberellic acid and 100%with 10 mM sodium nitrate.Approximately three shoots per seed were developed,an indication of polyembryony.Histochemical analyses revealed the presence of protein-like bodies close to the embryo axis and accumulations of starch after 7 days of germination.After 14 days,amyloplasts and dark protein bodies of various sizes were observed.The outcome of this study will contribute to improve the germination of P.africana for better domestication and conservation.Justine Germo Nzweundji Koffi Konan Leopold MNyochembeng Nehemie Donfagsiteli Tchinda Nicolas Niemenak 2020Journal of Forestry Research2020,31,6:1
