In Vitro Radical Scavenging Activity of Extracts from Dendrobium chrysotoxum in Yunnan
Objective To investigate the in vitro radical scavenging activity of extracts from Dendrobium chrysotoxum,including 95% ethanol,petroleum ether,ethyl acetate,n-butanol and methanol extracts.Methods DPPH radical scavenging activity method was used to research the in vitro activity of five crude extracts.Results The results showed that the ethyl acetate extract exhibited a good scavenging action (IC50 =0.12 mg/mL).Conclusion The extracts from D.chrysotoxum have a certain value in antioxidant aspect.
