Chemical constituents from aereal parts of Symplocos chinensis / 中草药

ABSTRACT

Objective: To study the chemical constituents from the aereal parts of Symplocos chinensis. Methods: The chemical constituents were isolated and purified by various column chromatographies. Their chemical structures were identified by physicochemical properties and spectral analyses. Results: Fourteen compounds were isolated from the the aereal parts of S. chinensis and identified as daucosterol (1), quercetin (2), quercetin-3-O-α-L-rhamnopyranoside (3), isoquercetrin (4), rutin (5), kaempferol-3- O-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside (6), niga-ichigoside F1 (7), shimobashiraside C (8), bergenin (9), protocatechuic acid (10), chrysophanol (11), aralia cerebroside (12), 2α, 3β, 19α, 23- tetrahydroxy-12-en-28-ursolic cid (13), and 2α, 3β, 19α, 23-tetrahydroxy-12-en-28-olenolic acid (14). Conclusion: Compounds 3, 5, 6, 8-12 are obtained from the plants of genus Symplocos Jacq. for the first time, and compounds 2-6 and 8-12 were obtained from the aereal parts of Symplocos chinensis for the first time.
