摘要
从担子菌地星(Astraeus hygrometricus)发酵培养菌丝体中分离得到一个新的多羟基甾醇酯,其化学结构通过波谱学方法包括二维核磁共振鉴定为:3β,5α-二羟基-(22E,24R)-麦角甾醇-7,22-二烯-6α-棕榈酸酯。同时还从该菌中分离得到其它三个甾醇类化合物。
A new steryl ester with a polyhydroxylated ergostane-type nucleus, 3β, 5α-dihydroxy-（22E, 24R ）-ergosta-7, 22-dien-6α-yl palmitate （1）, together with three known compounds （2-4） was isolated from the culture myeelia of the basidiomycete Astraeus hygrometricus. The structure of compound 1 was elucidated on the basis of extensive spectroscopic methods （IR, HR-FAB-MS, 1D and 2D NMR）.
