섬오가피의 추출 조건에 따른 페놀성 성분 함량 변화

This study compared the contents of phenolic components depending on the extracting conditions of Acanthopanax koreanum stem to provide basic information for developing Acanthopanax koreanum-based functional foods. Our findings show that the content of total phenolic component peaked at 16 hours of extraction (WAK-16, 7.22%) and when water extracted at $100^{\circ}C$. However, 11-hours water extraction (WAK-11) showed highest eleutheroside B concentration of 1.32%, a main component of A. koreanum, and the level of chlorogenic acid concentration was the highest when 1-hour water extraction (WAK-1) was conducted, being 2.12%. Moreover, highest concentration of eleutheroside E was observed in 16-hours water extraction (WAK-16) as 1.49%. With 60-hours water extraction (WAK-60), the content of syringaresinol, an active phenolic aglycon substance, concentration was the highest with the value of 0.10%. Isofraxidin showed the highest concentration of water extract(0.09%) for 20 hours (WAK-20) and 0.42% for sinapyl alcohol[16 hours (WAK-16)].
