摘要(Abstract):

[Objectives] To compare the anti-inflammatory activities of three extraction processes of the exotic plant Bidens alba(L.) DC in Lingnan(south of the Five Ridges in China).[Methods]The alcohol extracts of B.alba(L.) DC were extracted and separated with petroleum ether,chloroform and ethyl acetate respectively.The anti-inflammatory activity experiment of these three extracts was carried out with the RAW264.7 inflammatory model of mouse macrophages in vitro.[Results]When the concentration was 0.05-1.6 mg/L,the petroleum ether extract of B.alba(L.) DC produced strong inhibitory effects on nitric oxide(NO) release of RAW264.7 macrophages induced by LPS;the inhibition of ethyl acetate extract was weak,and the chloroform extract showed no significant inhibition.[Conclusions]Petroleum ether is the best extractant for active anti-inflammatory ingredients of B.alba(L.) DC.
