摘要: 目的:为发现更多高等真菌次级代谢产物,研究采自长白山的粉肉拟层孔菌Fomitopsis cajanderi 子实体的化学成分。方
法:采用常压硅胶柱色谱、凝胶色谱和中压液相色谱、制备高效液相色谱等手段对粉肉拟层孔菌子实体的三氯甲烷-丙酮-甲醇(体
积比为1∶1∶1)提取物进行分离纯化,利用核磁共振波谱等方法鉴定化合物结构。结果:从粉肉拟层孔菌子实体中分离得到6个
24-甲基羊毛脂甾烷型三萜化合物,分别为3α-(3′-methyl-carboxyacetoxy)-24-methylene-23-oxylanost-8-en-26-oic acid(1),
3α-(3′-methyl-carboxyacetoxy)-24-methyllanost-8-en-26-oic acid(2),3α-(3′-methoxy-1′,3′-dioxopropoxy)-24S-methyl-23-
oxo-25S-lanost-8-en-26-oic acid(3),12β,23S-epoxy-3α-(3′-methylcarboxy-actoxy)-24S,25S-24-methyllanost-8-en-23,26-γ
-latone(4),24-methyl-lanost-8,24-dien-23S,26-lactone(5)和3α-(3′-methoxy-1′,3′-dioxopropoxy)-24-methyl-lanost-8,24-
dien-23S,26-lactone(6)。结论:化合物1 和化合物2(分别命名为cajanderin A和cajanderin B)为未曾报道的新化合物,化合物
1~4 为首次从粉肉拟层孔菌中分离得到的三萜衍生物。

Abstract: Objective: To discover novel secondary metabolites from higher fungi, the chemical constituents of the fruiting bodies of
Fomitopsis cajanderi collected from the Changbai Mountain were investigated. Methods: The chloroform-acetone-methanol (volume ra⁃
tio=1∶1∶1) extract of the fruiting bodies was separated and purified using silica gel column chromatography, gel chromatography,
medium-pressure liquid chromatography, and preparative high-performance liquid chromatography. The structures of the isolated com⁃
pounds were elucidated by nuclear magnetic resonance spectroscopy and other spectroscopic techniques. Results: Six 24-methyl
lanostane-type triterpenoids were isolated from the fruiting bodies, identified as 3α-(3′-methyl-carboxyacetoxy)-24-methylene-23-
oxylanost-8-en-26-oic acid (1), 3α-(3′-methyl-carboxyacetoxy)-24-methyllanost-8-en-26-oic acid (2), 3α-(3′-methoxy-1′,3′-di⁃
oxopropoxy)-24S-methyl-23-oxo-25S-lanost-8-en-26-oic acid (3), 12β,23S-epoxy-3α-(3′-methylcarboxy-actoxy)-24S,25S-24-
methyllanost-8-en-23,26-γ-latone (4), 24-methyl-lanost-8,24-dien-23S,26-lactone (5) and 3α-(3′-methoxy-1′,3′-dioxopropoxy)-
24-methyl-lanost-8,24-dien-23S,26-lactone (6). Conclusion: Compounds 1 and 2, named cajanderin A and cajanderin B respec⁃
tively, are new compounds that have not been reported before. Compounds 1-4 are triterpenoid derivatives that were first isolated from
F. cajanderi.
