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).
Conclusion:
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.
