[Chemical constituents of Rheum wittrochii Lundstr(I)].
OBJECTIVE
To study the chemical constituents in the root of Rheum wittrochii.


METHODS
Chromatography and spectroscopic analysis were used to isolate and elucidate the chemical constituents in the plant.


RESULTS
Six compounds, namely chrysophanol, physcion, emodin, chrysophanol-8-O-beta-D-glucopyranoside, physcion-8-O-beta-D-glucopyranoside and beta-sitosterol, have been isolated from petroleum ether and ethyl acetate fractions.


CONCLUSIONS
All the above-cited compounds were isolated from the title plant for the first time, and anthraquinone compounds are some of the major constituents of R. wittrochii.
