[Studies on the chemical constituents of Rumex crispus].
OBJECTIVE
To study the chemical constituents of Rumex crispus.


METHODS
Compounds were isolated and purified repeatedly by silica gel, Sephadex gel and ODS C18 column chromatographies, and structure identifications of compounds were carried out by physical, chemical methods and spectral data.


RESULTS
Fifteen compounds were obtained from the petroleum ether and ethyl acetate fractions of R. crispus, and were identified as beta-sitosterol(1), hexadecanoic acid(2), hexadecanoic-2,3-dihydroxy propyleste(3), chrysophanol(4), physcion(5), emodin(6), chrysophanol-8-O-beta-D-glucopyranoside(7), physcion-8-O-beta-D-glucopyranoside(8), emodin-8O-beta-D-glucopyranoside(9), gallic acid(10), (+)-catechin(11), kaempferol(12), quercetin(13), kaempferol-3-O-alpha-L-rhamnopyranoside(14), quercetin-3-O-alpha-L-rhamnopyranoside(15).


CONCLUSIONS
Compounds 3,8-12,14 and 15 are obtained from R. crispus for the first time.
