Résumé
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-trihydroxy4-(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.

The column chromatography on silica gel, Sephadex LH-20 and semi-preparative HPLC were used to separate and purify the compounds from the EtOAc extract of medium and MeOH extract of cell cultures of Morus alba. Eight compounds were isolated. Based on physico-chemical properties and spectroscopic data, their structures were identified as isobavachalcone (1), genistein (2), norartocarpetin (3), albanin A (4), guangsangon E (5), mulberrofuran F (6), chalcomoracin (7), kuwanon J (8). Compounds 3-6 were isolated from the cell cultures of M. alba for the first time.
