| Abstract: | OBJECTIVE: To study anti-oxidant phenolic compounds from stem barks of Morus yunanensis. METHOD: Isolation and purification were carried out by silica gel, Sephadex LH -20 and RP - 18 column chromatography. The chemical structures of constituents were elucidated on the basis of physicochemical properties and spectral data. RESULT: Eight phenolic compounds were isolated and identified as: mulberrofuran E (1), mulberrofuran K (2), albanol B (3), kuwanon H (4), resveratrol (5), moracin M (6), morachalcone A (7), 3', 5', 2, 4-tetrahydroxy-4-(3-methyl-1-butenyl) stilbene (8). CONCLUSION: All the compounds were isolated from the plant for the first time, and compounds 2, 3, 6, 8 showed potent anti-oxidation activities. |
