ABSTRACT To study on the chemical constituents of root of Cynanchum auriculatum Royle ex Wight.
The constituents were isolated and purified by various chromatographic methods, and the spectroscopic methods (MS, NMR) were used to identify their sturctures.
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).
Compounds I-IV are isolated from this plant for the first time.
