Antimicrobial activity of compounds from Geum aleppicum
摘要
Abstract
The Minmum Inhibiting Concentration (MIC) of compounds isolated from Geum aleppicum were measured by microdilution method on 96-well plates against E .coli ,P . aeruginosa ,S .lactis ,S .aureus ,B .subtilis .The results showed that β-sitosterol ,ursolic acid , kaempferol ,quercetin ,kaempferol-3-O-β-D-glucoside ,quercetin-3-O-β-D-glucoside and daucosterol had inhibiting activity to the tested bacteria .Kaempferol had notable inhibi-ting microorganism activity to E .coli ,with the MIC 7 .8 μg/mL .The antioxidant effects of compounds kaempferol ,quercetin ,kaempferol-3-O-β-D-glucoside ,quercetin-3-O-β-D-glu-coside ,apigenin ,luteolin ,apigenin-7-O-β-D-glucoside and luteolin-7-O-β-D-glucoside were tested .The DPPH radicals-cavenging capacity was measured against various concentrations with ascorbic acid and BHT as contrasts .The result of antioxidant activity test showed that flavonols from Geum aleppicum have a good antioxidant activity .关键词
