Abstract

The sutdies were carried out to evaluate the consituents in the rihzomes of the cultivated Korean Rhubarb (Polygonaceae). From the acetone fraction ofl methanol extract Compound I (1, 8-dihydroxy-3-methyl anthraquinone, chrysophanic acid), Compound II($chrysophanol-8-O-{\beta}-D-glucopyranoside$), Compound III ($emodin-8-O-{\beta}-D-glucopyranoside$) and Compound IV ($aloe-emodin-8-O-{\beta}-D-glucopyranoside$), and from the ether fraction Compound V(1, 8-dihydorxy-3-emthyl-6-methoxy anthraquinone, physcion) and Compound VI (1, 6, 8-thitydroxy-3-emthyl anthrauinone, emodin), and also from the n-buthanol fraction Compound VII ($rhapontigenin-3-O-{\beta}-D-glucopyranoside, rhaponticin$) and Compound VIII ($piceatannol-3'-O-{\beta}-D-glucopyranoside$), were isolated and identified on the basis of their physico-chemical and spectroscopic evidences (UV, IR, H-NMR, C-NMR, EI-MS), respectively.
