OBJECTIVE
To study the chemical constituents of the twigs of Morus atropurpurea.
METHODS
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).
RESULTS
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).
CONCLUSIONS
Except compounds 9 and 11, all the other compounds were obtained from M. atropurpurea for the first time.
