Abstract

The optimum extraction condition of pungent component from Zanthoxylum piperitum D.C pericarps by using supercritical fluid extraction(SFE) was investigated. The optimum condition of SFE was $300kg/cm^2$ of pressure, $60\;^{\circ}C$ of extraction temperature, 80% of $CO_2$ fluid, 20% of modifier(methanol) volume and 20 min of extraction time. The extraction efficiency between the classical solvent extraction method and SFE was studied. About 40% of extraction efficiency was improved when SFE was applied.

초임계추출(SFE)를 이용한 초피나무 과피 중 신미성분의 최적추출조건을 조사하였다. 최적 추출 압력은 $300kg/cm^2$ 이었으며 온도는 $60^{\circ}C$, 추출 부피는 $12\;m{\ell}$, flow rate는 3m/min 그리고 modifier로 사용한 methanol의 함량비율은 20%였다. 추출시간은 초반 20분 안에 대부분의 신미성분이 추출되었다. 또한 용매추출법과 비교한 결과 추출효능이 약 40%정도 향상되었고 시간은 20분으로 단축되었으며 유기용매 methanol은 12 ml밖에 소요되지 않을 뿐만 아니라 주요한 추출용매로 무독성 액화$CO_2$를 사용하기에 독성 유기용매의 다량 사용을 피할 수 있는 친환경적이고 경제적인 방법으로 생각되어 진다.
