摘要: 运用硅胶柱、反相硅胶柱、凝胶柱、HPLC和薄层制备等色谱技术及重结晶从白木香内生真菌Botryosphaeria rhodina A13的固体发酵产物中分离纯化了10个化学成分,通过化合物波谱数据及理化性质鉴定它们的结构分别为豆甾-4-烯-3-酮(1)、豆甾-5-烯-3β-醇-7-酮(2)、豆甾-4-烯-3,6-二酮(3)、(22E, 24S)-5α,6α-环氧基-24-甲基胆甾-8(14),22-二烯-3β,7α-二醇(4)、5,4′-二羟-7-甲氧基黄酮(5)、香草酸(6)、对甲氧基苯甲酸(7)、尿嘧啶(8)、2-甲氧基对苯二酚(9)、2-甲基-3,5-羟基色酮(10)。其中化合物1~10均为首次从该属真菌中分离得到,化合物4具有细胞毒活性。

Abstract: Ten chemical constituents were isolated and purified from the solid culture of endophytic fungal strain Botryosphaeria rhodina A13 isolated from Aquilaria sinensis by silica gel column chromatography,reverse silica gel column chromatography,Sephadex LH20 column chromatography,HPLC,preparative TLC and recrystallization. On the basis of spectral data and physicochemical properties,their structures were identified as 3-oxo-Δ-4,5-sitosterone (1), (24R)-3β-hydroxyethylcholest-5-en-7-one (2), stigmast-4-ene-3,6-dione (3), (22E,24S)-5α,6α-epoxy-24-methylcholesta-8(14),22-diene-3β,7α-diol (4),genkwanin (5),benzoic acid (6),4-methoxybenzoic acid (7),pyrimidine-2,4(1H,3H)-dione (8),2-methoxyhydroquinone (9),(-)-gynuraone (10).All the compounds were isolated from the genus Botryosphaeria for the first time.Compound 4 showed cytotoxic activities against MCF-7 and NCI-H460 cell lines.

Key words: Botryosphaeria rhodina, endophytic fungus, secondary metabolite, Aquilaria sinensis ( Lour.) Gilg, cytotoxicity
