Instructions
Antifungal Activities of Crude Extractum from Camellia semiserrata Chi (Nanshancha) Seed Cake Against Colletotrichum musae, Colletotrichum gloeosporioides and Penicillium italicum in vitro and in vivo Fruit Test.[Pubmed: 26674222]
Antifungal activities of crude extractum of Nanshancha Seed Cake (NSC), to inactivate postharvest pathogens were investigated. Highest inhibitory rate was found against C. musae, C. gloeosporioides and C. papaya P.Henn, which was much stronger than that by tea saponin. Compared to tea saponin, effects of NSC extractum was relatively weak and similar on C. gloeosporioides Penzig and P. italicum. In an in vivo study, best controlling effects by NSC extractum was found with banana anthracnose disease development, which showed no inhibitory effects by tea saponin. NSC extractum controlled in vitro C. musae growth through directly inhibiting germination rate and germ tube elongation, and causing distortation, rupture and indentation of C. musae mycelium. In banana fruit subject to C. musae inoculation, higher PAL, POD, GLU and CHT activity was observed in banana fruit treated with crude NSC extractum than that of water control fruits. Current study proved the best controlling effects of crude NSC extractum in C. musae in vitro and in vivo development, which through direct inhibition of C. musae growth and increasing defense system of the banana fruit.
Flavonoids from seeds of Camellia semiserrata Chi. and their estrogenic activity.[Pubmed: 18776671]
Two new flavonol glycosides and three known flavonoids were isolated from seeds of Camellia semiserrata Chi. The structures of these new flavonol glycosides were established as kaempferol 3-O-[(2'''''',3'''''',4''''''-triacetyl)-alpha-L-rhamnopyranosyl(1-->3)(2'''',4''''-diacetyl)-alpha-L-rhamnopyranosyl (1-->6)-beta-D-glucopyranoside] and kaempferol 3-O-[(3'''''',4''''''-diacetyl)-alpha-L-rhamnopyranosyl(1-->3)(2'''',4''''-diacetyl)-alpha-L-rhamnopyranosyl(1-->6)-beta-D-glucopyranoside] by spectroscopic methods. The estrogenic activity of these compounds was investigated by a recombinant yeast screening assay.
