Objective To study the chemical constituents of Cynanchum auriculatum.Methods Two steroidal glycosides were purified by column chromatography and their structures were elucidated by spectroscopic analysis.Results and Conclusion Compound 1 is a new steroidal glycoside,named kidjoranin-3-O-β-D-cymaropyranoside.Compound 2 is isolated from this plant for the first time.
