OBJECTIVE
To study the chemical constituents from aerial part of Rumex patientia.
METHODS
The compounds were isolated and purified by silica gels and polyamide column chromatography. Their structures were elucidated by physicochemical and spectroscopic evidences.
RESULTS
Twelve compounds were identified as: chrysophanol (1), chrysophanol-8-O-beta-D-glucopyranoside (2), physcion (3), emodin(4), emodin-8-O-beta-D-glucopyranoside (5), maackiain (6), maackiain-3-O-beta-D-glucopyranoside (7), quercetin-3-O-beta-D-glucopyranoside (8), quercetin-3-O-beta-D-glucuronide(9), 2-O-methylinositol (10), torachrysone-8-O-beta-D-glucopyranoside (11) and nepodin-8-O-beta-D-glucopyranoside (12).
CONCLUSIONS
Compounds 6, 7, 10 are isolated from this genus for the first time, and compound 9 is isolated from this plant for the first time.
