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
