Abstract

Comparison of four phenolic compounds among three different parts of Panax ginseng C.A. Meyer was performed in this study. Contents of esculetin, p-coumaric acd, quercetin, maltol in the ethyl acetate fraction were determinated by HPLC analysis. The main root has a highest concentration of p-coumaric acid and the leave has a highest concentration of quercetin and esculetin. This ethyl acetate fraction of the leaves exhibited higher depigmenting activity and lower cell toxicity than the other parts of ginseng. In addition, it showed that quercetin and esculetin among phenolic compounds highly inhibited melanin biosynthesis in ginseng. It implies that leaves of ginseng may be used as skin whitening herb. Quercetin and esculetin proved to be active compounds in the leaves of ginseng.

국내산 인삼의 부위별 quercetin, p-coumaric acid, maltol, esculetin의 함량을 측정한 결과 잎에서는 quercetin과 esculetin이 주근에서는 p-coumaric acid가 다량 함유되어 있었다. 이중잎의 EA 분획물은 melan-a 세포주에서 뛰어난 멜라닌 생성억제 활성을 보였으며, 이의 주요성분인 quercetin과 esculetin이 tyrosinase 활성억제도, melan-a 세포주에서의 멜라닌 생성억제도, UV-흡수도 측정에서 모두 우수한 활성을 나타내는 결과로 미루어 인삼의 잎은 피부미백을 목적으로 하는 기능성 소재로 이용될 수 있는 가능성을 가지는 것으로 사료된다.
