Abstract:
This article was aimed to study the chemical constituents from the chemical split fractions of Mori Cortex. The compounds were isolated with Diaion HP-20, Toyopearl HW-40, Sephadex LH-20, MCI Gel CHP-20, Silica gel column chromatography and preparative HPLC. Structures of compounds were identified by physicochemical properties and spectral analysis. The results showed that 23 compounds were obtained. And their structures were identified. The 16 compounds were obtained from the 30% ethanol fraction as vanillic acid (1), 3,4-dimethoxyphenol (2), benzoic acid (3), syringic acid (4), kelampayoside A (5), p-hydroxyphenylpropionic acid (6), caffeic acid (7), hydroferulic acid (8), 6,7-dihydroxycoumarin (9), 5,7-dihydroxycoumarin (10), morin-7-O-β-D-glucopyranoside (11), liriodendrin (12), 2,3-trans-dihydromorin (13), 2,3-cis-dihydromorin (14), 2,3-trans-dihydroquercetin (15), 2,3-cis-dihydroquercetin (16). The 4 compounds were obtained from the 50% ethanol fraction as scopoletin (17), morin (18), kaempferol-7-O-β-D-glucopyranoside (19), umbelliferone (20). The 3 compounds were obtained from the 80% ethanol fraction as sanggenon R (21), cis-mulberroside A (22), resveratrol (23). It was concluded that compounds 2, 4-6, 11, 16, 19 were isolated from this plant for the first time.
