초록

국내 자생버섯인 까치버섯(Polyozellus multiflex의 메탄을 추출물로부터 이 버섯이 생산하는 2차 대사산물을 조사한 결과 기 보고된 주 2차 대사산물인 polyozellin 이외에 미량 2차 대사산물로서 4가지 화합물이 단리되었으며 이들은 각종 spectral analysis에 의하여 각각 ergost-4,6,8,22-tetraen-3-one, 4-methoxy-6-methyl-2H-pyran-2-one, p-anisic acid, 및 p-hydroxybenzoic acid로 동정되었다. 이들에 대하여 prolyl endopeptidase 및 acetylcholine esterase에 대한 저해 활성을 측정하였으나 최고 100 ppm의 농도에서도 저해활성을 나타내지 못하였다.

Abstract

Four minor compounds were isolated from fruiting bodies of Polyozellus multiflex by consecutive chromatographic separation. Their structures were identified as ergost-4,6,8,22-tetraen-3-one, 4-methoxy-6-methyl-2H-pyran-2-one, p-anisic acid, and p-hydroxybenzoic acid by spectral analysis. They could not inhibit prolyl endopeptidase nor acetylcholine esterase at the concentration up to 100 ppm.
