Abstract
|
|
|
|
The research was conducted to identify the antimicrobial effect, anti-oxidative effect and tyrosinase inhibitory effect of MeOH 80% extract and n-hexane, chloroform, ethyl acetate, n-butanol and water fractions from the extract of six kinds of compositae plants, which are naturally grown across the nation. In the antimicrobial effect, the extract and chloroform fraction of Arctium lappa and hexane/ethyl acetate fractions of Taraxacum platycarpumexhibited significant inhibition. In case of antioxidant effect, the extract of Artemisia capillaries showed the highest effect and ethyl acetate/butanol fractions of all plants showed about 90%, which fractions were more polar than the fractions that showed antimicrobial effect. In case of tyrosinase activity, only the MeOH 80% of Arctium lappa among the extracts showed a potent inhibition, and butanol fraction of Chrysanthemum indicum, as well as ethyl acetate/water fractions of Artemisia capillaries showed 48, 38, and 37% respectively, which were higher than control group (arbutin). These active fractions in tyrosinase inhibition also were higher polarity than those that showed antimicrobial effect. In MeOH 80% extracts, only Arctium lappa was found to have antimicrobial, anti-oxidant and tyrosinase inhibitory activity, however there was no fraction to show effects commonly in the three assay system.
