两株多孔菌属担子菌菌丝体中的三萜成分

Triterpenes from the Mycelial Cultures of Two Polyporus Strains

摘要:

用组织分离法从采集于广东鼎湖山的2株多孔菌属担子菌子实体中分离得到2株菌丝体，并对菌丝体分别进行固体发酵培养，培养物经乙醇提取后，用柱层析分离得到4个化合物，用光谱法鉴定均为羊毛脂烷型三萜，它们分别是多孔菌酸C（polyporenic acid C）（1）、茯苓酸（pachymic acid）（2）、齿孔酸（eburicoic acid）（3）和硫磺菌酸（sulphurenic acid）（4）。其中化合物2为首次从多孔菌属中发现。

Abstract:

Two strains of fungal mycelia, SC0351 and SC0652, were obtained from tissue culture of the fruiting bodies of two Polyporus from Basidiomycetes collected at Dinghushan, Guangdong Province, China. From the solid cultures of these fungi, four lanostane-type triterpenes were isolated by using column chromatography. They were identified by spectral analysis as polyporenic acid C （1）, pachymic acid （2）, eburicoic acid （3） and sulphurenic acid （4）. Compound 2 was obtained from Polyporus for the first time.
