摘要
A new anthraquinone glycoside, emodin-6-O-beta -D-glucopranoside, and a new simple halogenated flavan-3-ol, 6-chlorocatechin, have been isolated from the roots of Rumex patientia L. together with seven known phenolic compounds. Their structures were elucidated on the basis of spectroscopic methods. Cytotoxic effects and radical scavenging properties of the isolated compounds have been demonstrated.
