Abstract
OBJECTIVE
Investigating the chemical constituents in the root of Rumex patientia.
METHODS
Compounds were separated by rechromatography on silica gel. Their structures were determined by spectral analysis and chemical evidence.
RESULTS
Eight compounds were isolated and identified as 5-methoxy-7-hydroxy-1 (3H)-benzofuranone (I), 5, 7-dihydroxy-1 (3H)-benzofuranone(II), nonadecanoic acid-2,3-dihydroxypropyl ester(III), torachrysone-8-O-beta-D-glucopyranoside(IV), gallic acid(V), beta-sitosterol(VI), beta-sitosterol-3-O-beta-D-glucopyranoside(VII) and catechin(VIII).
CONCLUSIONS
Compound III is a new natural products, and compounds I and II were obtained from this plant for the first time.
