摘要
采用硅胶柱色谱及HPLC等分离方法对桦褐孔菌正己烷提取物进行分离纯化,得到7个三萜类化合物。依据波谱数据分析鉴定它们的结构分别为:白桦脂酸(1),白桦醇(2),羽扇豆醇(3),8,24-羊毛甾二烯-3β,21β-二醇(4),3β-羟基-羊毛甾-8,24-二烯-21-醛(5),8,23(E)-二烯羊毛甾-3β,22(R),25-三醇(6),桦褐孔菌醇D(7)。其中化合物7为首次从野生桦褐孔菌中分离得到。
The chemical constitutes were isolated and purified by chromatography of silica gel column and HPLC from n-hexane extract of Inonotus obliquus, and the structures were elucidated by spectral analysis. Seven compounds were isolated and identified as betulinic acid（1）, betulinic alcohol（2）, lupeol（3）, lanosta-8,24-diene-3β,21β-diol（4）,3β-hydroxy-lanosta-8,24-diene-21-al（5）, lanosta-8,23（E）-diene-3β,22（R）, 25-triol（6）, foscoparianol D（7）. The compound 7 isolated from Inonotus obliquus for the first time.
