大白口蘑子实体化学成分研究

Study on the Chemical Constituent of Tricholoma giganteum Massee

从担子菌大白口蘑(Tricholoma giganteum Massee)新鲜子实体提取物中首次分离得到5个化合物,它们的结构经各种波谱数据分别鉴定为(22E,24R)-麦角甾-5,7,22-三烯-3β-醇;5α,8α-桥氧-(22E,24R)-麦角-6,22-二烯-3β-醇;(2S,3S,4R,2’R)-2-(2’-羟基二十一碳酰胺基)-三十烷基-1,3,4-三醇;腺嘌呤核苷和烟酸。

Four known compounds were extracted from the fresh fruiting bodies of Trcholoma giganteum Massee. Their structure identified and isolated by means of spectral and chemical methods were （22E,24R）-ergosta-5,7,22-trien-3β-ol;5α,8α-epidioxy-（22E,24R）-ergosta-6,22-dien-3β--ol; （ 2S,3S,4R, 2＇ R ） -2- （ 2＇-hydroxytetraco 21 Carbon-lactamase ） -30 alkyl- 1,3,4- triol; adenosine and nicotinic acid, respectively. All the compounds were isolated from T. gigameum for the first time.
