摘要:

采用硅胶及凝胶柱色谱方法从赤芝(Ganoderma lucidum (Leyss.ex Fr.) Karst.)子实体的乙醇提取物中分离得到10个化合物,通过波谱数据及理化性质分别鉴定为赤芝萜醇A(lucidumol A,1)、麦角甾醇(ergosterol,2)、麦角甾醇棕榈酸酯(ergosteryl palmitate,3)、棕榈酸(palmitic acid,4)、β-谷甾醇(β-sitosterol,5)、硬脂酸(stearic acid,6)、油酸(oleic acid,7)、α-羟基-24-烷酸(α-hydroxytetracosanoic acid,8)、2-羟基-二十四烷酸乙酯(2-hydroxytetracosanoic ethyl ester, 9)以及2-羟基-二十四烷酸甲酯(2- hydroxytetracosanoic methyl ester,10)。其中,化合物910首次从该属植物中分离得到,48首次从该植物中分离得到。

Abstract:

Ten compounds were isolated and purified from the ethanol extract of fruiting bodies of Ganoderma lucidum by using column chromatography on silica gel and Sephadex LH-20. On the basis of spectral data and physicochemical properties, their structures were elucidated as lucidumol A (1), ergosterol (2), ergosteryl palmitate (3), palmitic acid (4), β-sitosterol (5), stearic acid (6), oleic acid (7), α-hydroxytetracosanoic acid (8), 2-hydroxytetracosanoic ethyl ester (9), and 2-hydroxytetracosanoic methyl ester (10). This is first report of the presence of compounds 9 and 10 in the genus Ganoderma and 4~8 in this plant.

Key words: Ganoderma lucidum (Leyss.ex Fr.) Karst., fruiting body, α-hydroxy tetracosanoic acid, 2-hydroxy tetracosanoic ethyl ester, 2- hydroxyl tetracosanoic methyl ester
