[Abstract]
Objective To study the chemical composition from the stems and leaves of Sabia parviflora and their liver-protecting activity. Methods Normal phase, reverse phase silica gel column chromatography, gel column chromatography and semi-preparative liquid chromatography were used for separation and purification, and the structures of the isolated compounds were identified by NMR and MS. Results Twenty-two compounds were isolated from the stems and leaves of S. parviflora, including N-trans-feruloyl tyramine (1), oleic acid (2), (Z)-1, 8-Heptadeca diene (3), N-trans-p-coumaroyl octopamine (4), (Z)-N-formyl-nornuciferin(Z) (5), N-demethyl-N-formyldehydronuciferine (6), N-trans-cinnamoyltyramine (7), oleamide (8), 1,2,4-trimethoxybenzene (9), 2-(3-methoxyphenyl) isoindoline-1,3-dione (10), cheliensisaminone (11), squamolone (12), betulinic acid methyl ester (13), betulinic acid (14), 3-oxooleanolic acid (15), arctiin (16), 2-(3'',4''-dimethoxybenzyl)-3-(3'-methoxy-4'-hydroxybenzyl)-γ-butyrolactone (17), matairesinol (18), lappaol F (19), kaempferol (20), lappaol A (21), and lappaol B (22). Conclusion Compounds 2, 3, 5—8, 10—12, and 16—19 are isolated from Sabia genus for the first time. Among them, compounds 8, 11, 13, 14, 16, 20, and 22 have showed significant hepatoprotective activities.
