摘    要:从绿盖粉孢牛肝菌(Tylopilus virens)中分离得到一个新的麦角甾烷型甾体糖苷,其化学结构通过波谱学方法鉴定为:(22E,24R)-麦角甾-7,22-二烯-5α,6β-二醇-3β-O-3-(3-苯基丙酰氧基)]-β-D-葡萄吡喃糖苷,命名为tylopiloside(1),同时,其苷元cerevisterol(2)也从该菌中分离得到。值得注意的是,这种糖片段上有芳环取代的烷酰氧基基团的麦角甾烷型甾体糖苷为真菌中首次报道。

关 键 词:绿盖粉孢牛肝菌  甾体糖苷

Abstract:A new ergostane-type steroidal glycoside, named tylopiloside (1), was isolated from the fruiting bodies of Tylopilus virens together with its aglycone, cerevisterol (2). The structure of the new compound was elucidated as (22E,24R) -ergosta-7, 22-dien-5α, 6β-diol-3β-O- 3-(3-phenylpropanoyloxy )]-β-D-glucopyranoside on the basis of spectroscopic analysis. It is worth while to note that the steroidal glycoside possessing an aromatic ring substituted alkanoyl group at its glucose moiety was found for the first time in fungi.
Keywords:tylopiloside  Tylopilus virens  Steroidal glycoside  Tylopiloside
