To study the chemical constituents of the leaves of Polygonum multiflorum.
The chemical constituents were extracted with water and separated by manifold chromatography technique, and their structures were determined by spectral analysis.
Eleven compounds were isolated and identified as physcion (I), emodin (II), noreugenin (III), apigenin (IV), hyperoside (V), rutin (VI), vitexin (VII), 2,3,5 ,4'-tetrahydroxy-stibene-2-O-beta-D-glucoside (VIII), beta-amyrin (IX), beta-sitosterol (X), daucosterol(XI).
Among these compounds, I - IV, VI - XI are isolated from the leaves of Polygonum multiflorum for the first time.
