Abstract

In the course of phytochemical studies of Rumex acetosella L. (Polygonaceae), the MeOH extract of the whole plants was fractionated with $CH_2Cl_2$ and $H_2O$, and the $CH_2Cl_2$ layer was fractionated again with 90% MeOH and hexane. Whereas $H_2O$ layer was fractionated with EtOAc and then with n-BuOH again. By repeated column chromatography, compound 1 was isolated from the 90% MeOH fraction, compounds 1, 2, 3, 4 and 5 were from the ethylacetate fraction, and compound 5 was from the n--BuOH fraction. On the basis of physico-chemical, spectroscopic evidences and in comparison with authentic samples, the structures of them were confirmed to emodin, citreorosein, $chrysophanol-8-O-{\beta}-D-glucopyranoside$, luteolin and $luteolin-7-O {\beta}-D-glucopyranoside$.
