OBJECTIVE
To study the chemical constituents of roots of Rumex patientia.
METHODS
The compounds were separated and purified by silica column chromatopraphy, Sephadex LH-20 and identified by several spectroscopic methods.
RESULTS
Seven constituents were identified as nepodin (1),
Three novel and two known naphthalene glycosides were isolated from the roots of Rumex patientia L. (Polygonaceae). The structures of the new compounds were established, respectively as 2-acetyl-3-methyl-6-carboxy-1,8-dihydroxynaphthalene-8-O-beta-D-glucopyranoside,
OBJECTIVE
