Abstract:
AIM To study the chemical constituents from the twigs of Morus alba L..METHODS The 60％ ethanol extract from M.alba twigs was isolated and purified by ODS,sephadax LH-20 and semi-preparative column,then the structures of obtained compounds were identified by physicochemical properties and spectral data.RESULTS Ten compounds were isolated and identified as 4'-O-β-D-glucopyranosyl-2'-hydroxyresveratrol 3-(6-O-β-D-glucopyanosyl-β-D-glucopyranoside) (1),3-O-β-D-glucopyranosyl-2'-hydroxyresveratrol 4'-(6-O-β-D-glucopyanosyl-β-D-glucopyranoside) (2),mulberroside A (3),mulberroside E (4),mulberroside F (5),transoxyresveratrol-4'-O-β-D-glucopyranoside (6),trans-oxyresveratrol 3-O-β-D-glucopyranoside (7),cis-mulberroside A (8),3,4-dimethoxyphenyl β-D-apiofuranosyl-(1→6)-β-D-glucopyranoside (9),kelampayoside A (10).CONCLUSION Compounds 9 and 10 are isolated from genus Morus for the first time,compounds 1,2,4-7 are first isolated from this plant.
