摘要:

为了研究桦褐孔菌的化学成分并探究其胆碱酯酶抑制和细胞毒活性。采用各种柱色谱方法从桦褐孔菌乙酸乙酯部分中分离得到12个单体化合物,通过现代波谱学技术分别鉴定为monogynol A(1)、桦木酸(2)、白桦酯醇(3)、羊毛甾醇(4)、inoterpene D(5)、inonotsutriol C(6)、(3β,5α,6β,22E)-6-methoxyergosta-7,22-diene-3,5-diol(7)、过氧化麦角甾醇(8)、香草酸(9)、2-(3′,4′-二羟苯基)-1,3-胡椒环-5-醛(10)、2,3-二羟基-1-(4-羟基-3,5-二甲氧基苯基)-1-丙酮(11)和3-hydroxy-1-(4-hydroxy-3,5-dimethoxyphenyl)propan-1-one(12),其中化合物1、10和11为首次从桦褐孔菌中分离得到。活性测试结果表明化合物2、3、4和6有较好的丁酰胆碱酯酶抑制活性,2和3有较好的乙酰胆碱酯酶抑制活性;化合物1、5和6有较好的细胞毒活性。

Abstract:

To study the chemical constituents of Inonotus obliquus and their cytotoxicity and cholinesterase inhibitory activity.With various chromatographic methods,twelve compounds were isolated from the ethyl acetate fraction of I. obliquus. Their structures were identified on the basis of spectroscopic data analysis as monogynol A (1),betulinic acid (2),betulin (3),lanosterol (4),inoterpene D (5),inonotsutriol C (6),(3β,5α,6β,22E)-6-methoxyergosta-7,22-diene-3,5-diol (7),ergosterol peroxide (8),4-hydroxy-3-methoxybenzoic acid (9),2-(3,4-dihydroxyphenyl)-1,3-benzodioxole-5-carboxaldehyde (10),2,3-dihydroxy-1-4-hydroxy-3,5-dimethoxyphenyl-1-acetone (11),3-hydroxy-1-(4-hydroxy-3,5-dimethoxyphenyl) propan-1-one (12).Compounds 1,10 and 11 were isolated from the I. obliquus for the first time.The bioassay results showed that compounds 2,3,4,and 6 displayed butyrylcholinesterase inhibitory activity; Compounds 2 and 3 showed acetylcholinesterase inhibitory activity;compounds 1,5,and 6 exhibited moderate cytotoxic activity.

Key words: Inonotus obliquus, chemical constituent, cholinesterase, cytotoxicity
