Abstract

The antioxidative activity was observed in the ethyl acetate extract $(IC_{50},\;119{\pm}0.16\;{\mu}g/mL)$ from Pueraria thunbergiana. The DPPH radical scavenging effect of this extract was comparable with that of synthetic antioxdant, BHA $(IC_{50},\;88.39{\pm}1.1\;{\mu}g/mL){\times}\;10^{-3}\;{\mu}M$. Pueraria thunbergiana extracts against microorganisms were evaluated in terms of the minimum inhibitory concentrations (MIC). In general, C. albicans was stronger antimicrobial activity than the other microorganisms. in vitro the antitoxic activity of extracts of Pueraria thunbergiana on NIH 373 fibroblasts was evaluated by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromide) method. Generally, detoxification effect by the extracts of Pueraria thunbergiana increased in proportion to the concentrations. When $10\;{\mu}g/mL$ of the hexane extract of Pueraria thunbergiana was treated it showed the highest antitoxic effects (p<0.01). These results suggest that the crude extract of P. thunbergiana has a potential therapeutic activity.
