Abstract

We have investigated the secondary metabolites from the mushroom Suillus granulatus. The methanolic extract of fruit body was separated by silica gel and Sephadex LH-20 column chromatographies. TLC and HPLC were also used for the further purification on compounds from the extracts, Nine compounds were finally isolated and their structures were assigned as 4-hydroxyphenylacetic acid 4-hydroxybenzaldehyde 2,5-dihydroxybenzoic acid methyl ester 5'-deoxy-5'methylthioadenosine. indole-3- carboxlic acid methyl ester indole 3-carboxaldehyde 1,3,5-trihydroxy 7-methylanthraquinone nicotinamide and 3-geranylgeranyl-4-hydroxybenzoic acid on the basis of NMR studies.

버섯유래 저분자 대사산물을 탐색하던 중 대전근교에서 채집한 젖비단 그물버섯(Suillus granulatus)으로 부터 9종의 화합물을 분리하였다. 젖비단 그물버섯을 메탄올로 추출한 후 용매분획하여 그 중 대산산물이 많이 함유된 chloro-form 층 및 ethyl acetate층 에 대하여 각각 silica gel 및 Sephadx LH-20 column chromatography를 수행하였다. 주요대사산물을 함유하고 있는 분획물을 TLC및 분취용 HPLC를 사용하여 정제한 결과 9종의 화합물을 분리하였다. 분리된 화합물의 화학구조를 규명하기 위하여 NMR 및 mass 분석을 수행하여쓰며 그 결과 이들의 화합물은 4-hydro-xyphenylacetic acid, 4-hydroxybenzaldhyde, 2, 5-dihydro-xybenzoic acid methyl ester, 5-deoxy-5 methylthioadeno- sine. indole 3-carboxlic methyl ester indole-3-carbox-aldehyde 1,3,5-trihydroxy 7-methylanthraquinone nicotinamide, 3-geranylgeranyl-4-hydroxybenzoic acid로 동정하였다.
