phytosterols and morusin

To study the chemical constituents of the twigs of Morus atropurpurea.. The compounds of the EtOAc fraction were isolated and purified by column chromatography on silica gel, polyamide, Sephadex LH -20, and their structures were elucidated on the basis of spectroscopic evidence (MS, NMR).. Eleven compounds were identified as mulberrin (1), cyclomulberrin (2), morusin (3), cyclomorusin (4), 2', 4',4, 2"-tetrahydroxy-3'-{3"-methylbut-3"-enyl-}-chalcone (5), mulberrofran G (6), scopoletin (7), moruchalcone A (8), kaempferol (9), ursolic acid (10), beta-daucosterol (11).. Except compounds 9 and 11, all the other compounds were obtained from M. atropurpurea for the first time.
