As the continued studies for Korean cultivated rhubarb, MeOH extract of the leaves was fractionated with ether, ethylacetate, and n-butanol. From the ethyl acetate fraction of MeOH extract, one flavone glycoside, apigenin-8-beta-D-glucopyranoside(vitexin, C2lH20010) and from the n-BuOH fraction of MeOH extract, two flavonol glycosids, kaempferol-3-0-(2,6-di-O-rhamnopyranosyl)-beta-D-galactopyranoside(C33H40019,/SUB>)and quercetin-3-0-rutinoside(rutin, C27H30O16) were isolated and identified through the physico-chemical properties and spectroscopic evidences(UV, IR, NMR, Mass) respectively.
