Besides the emodin, three anthraquinone derivatives were isolated from the roots of Polygonum ciliinerve (Nakai) Owi which is indigenous exclusively to Korea. Two of them were identified as physcion and emodin-8-O-${\beta}$-D-glucoside by mp, uv, ir and nmr spectra. And the third was converted to physcion and sugar by hydrolysis. The quantitative analysis of free and combined form of emodin and physcion was done by the spectrophotometry.
