Chemical Constituents from Leaves of Oplopanax horridus

ObjectiveTo study the chemical constituents from the leaves of Oplopanax horridus.MethodsThe chemical constituents were isolated and purified by column chromatography on silica gel and Sephadex LH-20 gel columns, 1H-NMR and 13C-NMR were applied for the identification of chemical structure.ResultsTen compounds were isolated and identified as dammara-20,24-dien-3β-ol acetate (1), phytol (2), 16Z,19Z-pentacosadienoic acid (3), β-sitosterol (4), (3S,8S-falcarindiol (5), maltol (6), acankoreagenin (7), daucosterol (8), stigmasterol-3-O-β-D-glucopyranoside (9), and acankoreoside A (10).ConclusionCompounds 1–3, 6, and 10 are isolated from this plant for the first time. Compounds 1–3 and 6 are isolated from the plants in genus Oplopanax Miq. for the first time. Moreover, Compounds 1, 3, and 6 are isolated from the plants in the family of Araliaceae for the first time.
