High-speed countercurrent chromatography (HSCCC) was applied to the se
paration and purification of 2,3,5,4'-tetrahydroxy stilbene-2-O-D-gluc
oside from dried roots (2.7g) of Polygonum multiflorum. The ethanol ex
tract (240 mg) was first separated with the solvent system composed of
ethyl acetate-ethanol-water at a volume ratio of 10:1:10 and the obta
ined fraction was repurified with the solvent system at the modified v
olume ratio of 50:1:50, The method produced stilbene glucoside (30mg)
at a high purity of 96%. The chemical structure was identified by FAB-
MS and (HNMR)-H-1.
