[Chemical constituents in the root of Cynanchum auriculatum].
OBJECTIVE
To study on the chemical constituents of root of Cynanchum auriculatum Royle ex Wight.


METHODS
The constituents were isolated and purified by various chromatographic methods, and the spectroscopic methods (MS, NMR) were used to identify their sturctures.


RESULTS
Seven compounds were obtained and identified as: taraxasterol acetate (I), cynanchone A (II), succinic acid (III), betulinic acid (IV), kidjoranin (V), wilfoside CIN (VI), wilfoside KIN (VII).


CONCLUSIONS
Compounds I-IV are isolated from this plant for the first time.
