Abstract:Ten compounds were isolated and purified from cell suspension cultures of Cudrania tricuspidata with silica-gel column chromatography, semi-preparative HPLC and Sephadex LH-20. On the base of their physicochemical properties and spectral data, their structures were identified as 1, 3, 5-trihydroxy-4-(3, 3-dimethylallyl)xanthone(1), wighteone(2), 6-prenylapigenin(3), licoflavone C(4), cudraflavanone C(5), erythrivarone A(6), derrone(7), carthamidin(8) , genistein(9) and aromadendrin(10). Among them, compounds 2-10 were flavonoids, and compound 1 was a xanthone which was isolated from the plant for the first time.
