Abstract

|
This study was conducted to investigate tyrosinase inhibitory effect, hyaluronidase inhibitory effect and antioxidant activity by DPPH radical scavenging method on the MeOH extract of 50 species medicinal plant for screening of functional properties. As a result, Chaenomeles sinensis Koehne extract among 50 species medicinal plant turned out to be having tyrosinase, hyaluronidase inhibitory effect and antioxidant activity. The major component of tyrosinase and hyaluronidase inhibitory effect was isolated from EtOAc extract of Chaenomeles sinensis Koehne. And the component of antioxidant activity was isolated from n-BuOH extract of Chaenomeles sinensis Koehne. Their structure of compounds were identified as oleanolic acid and (-)-epicatechin by spectroscopic evidence, respectively.
