Abstract

|
|
|
Rumex species (Polygonaceae) is widely distributed in Korea and its little sprout has been used as wild greens. The roots of Rumex sp. are used as a substitute for Rhei Rhizoma in Korea for its antipyretic and laxative properties. For the purpose of researching the value of Rumex sp. plants as natural resources, pattern recognition for the analysis of those plants was conducted using HPLC method. Two anthraquinone compounds, chrysophanol and emodin, were isolated from Rumex crispus to use standards. Chrysophanol and emodin from R. crispus were detected at retention time of 14.96 and 12.21 min, respectively. These compounds were detected from Rhei Rhizoma and all Rumex sp. plants. The content of chrysophanol of R. conglomeratus was higher than any other Rumex sp. plants. The amount of emodin was much higher from R. crispus than any other Rumex sp. The HPLC patterns of Rumex sp. are similar to that of Rhei Rhizoma, so they have something valuable as natural resources.
