Abstract:
OBJECTIVETo study the chemical constituents of the twigs of Morus atropurpurea.
METHODThe 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).
RESULTEleven 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).
CONCLUSIONExcept compounds 9 and 11, all the other compounds were obtained from M. atropurpurea for the first time.
