摘要: 采用硅胶柱、凝胶柱等色谱技术及重结晶从牡蒿内生真菌Pestalotiopsis uvicola GMH31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胸腺嘧啶(1)、尿嘧啶(2)、木犀草素(3)、芦丁(4)、槲皮素(5)、香草酸(6)、原儿茶酸(7)、山奈酚(8)、染料木素(9)、柚皮素(10)。其中化合物1~10均为首次从P.uvicola中分离获得,化合物3~5、8~10为黄酮类化合物,化合物8对A2780/Taxol细胞耐药性的逆转作用相对较强。

Abstract: Ten chemical constituents were isolated and purified from the solid culture of endophytic fungal strain Pestalotiopsis uvicola GMH31 isolated from Artemisia japonica by silica gel column chromatography,Sephadex-LH20 column chromatography and recrystallization.On the basis of spectral data and physicochemical properties,their structures were identified as thymine (1),uracil (2),luteolin (3),rutin (4),quercetin (5),vanillic acid (6),protocatechuic acid (7),kaempferol (8),genistein (9) and 4′,5,7-trihydroxyflavanone (10).All the compounds were isolated from P.uvicola for the first time,and compound 3~5 and 8~10 belong to flavonoids.Compound 8 showed better reversal effect on the ovarian cancer cell line A2780/Taxol.

Key words: Pestalotiopsis uvicola, endophytic fungus, secondary metabolite, Artemisia japonica
