OBJECTIVE: To study on the chemical constituents from rattan of Polygonum multiflorum. METHODS: The chemical constituents were extracted with alcohol and were separated with manifold chromatography technique. Their structures were determined by spectral analysis. RESULTS: Thirteen compounds were isolated and identified as Chrysophanol(I), Physcion(II), Emodin(III), Aloeemodin(IV), Rhein(V), Physcion-8-O-beta-D-glucoside(VI), Emodin-8-O-beta-D-glucoside (VII),2,3,5,4'-Tetrahydroxy-stibene-2-O-beta-D-glucoside(VIII), Noreugenin(IX), Apigenin(X), Daucosterol(XI), beta-Sitosterol(XII), Stearic acid(XIII). CONCLUSION: Among these, compounds I, IV-VI, VIII-XI, XIII are isolated from rattan of Polygonum multiflorum for the first time.
