To study on the chemical constituents from rattan of Polygonum multiflorum.
The chemical constituents were extracted with alcohol and were separated with manifold chromatography technique. Their structures were determined by spectral analysis.
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).
Among these, compounds I, IV-VI, VIII-XI, XIII are isolated from rattan of Polygonum multiflorum for the first time.
