Abstract
Three species of genus Polygonum, namely P. cuspidatum, P. sachalinense and P. ellipticum are distributed in Korea. Polygonum ellipticum Migo is a perennial herb in Polygonaceous plants. The root of the plant (Polygoni Rhizoma, 'Ho-jang') have been used as laxative, diuretic and for the treatment suppurative dermatitis in the oriental medicine. As the part of the study for the comparison of the three species in their components, the authors attempted to isolate the anthraquinones and stilbene derivative from the rhizome of P. ellipticum. The methanolic extract of dried rhizome of this plant was fractionated into ether soluble and insoluble fraction and each fraction was applied to column chromatography to isolate above mentioned components. Anthraquinone derivatives were isolated first; comp. I, mp
