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.
