Abstract
Objective:
To study the chemical constituents in the root of Rheum wittrochii.
Method:
Chromatography and spectroscopic analysis were used to isolate and elucidate the chemical constituents in the plant.
Result:
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.
Conclusion:
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.
