Object To study the chemical consti tuents of whole plant Ixerissonchifolia. Methods Various chromatographic techniques were employed for the isolation and purif i cation of its constituents; and structurally identified by spectral analysis (IR ， ESI-MS， 1HNMR， 13CNMR， HMQC and HMBC) and chemical eviden ces. Results 6 compounds were identified from its chloroform e xtract as: taraxaster-20-en-3β，16α-diol-3-acetate (Ⅰ); taraxasteryl ac etate (Ⅱ); (E)-2， 5-dihydroxy cinnamic acid (Ⅲ); luteolin (Ⅳ); palmitic acid (Ⅴ); and β-sitosterol (Ⅵ). Conclusion Co mpound Ⅰ was a new compound and Ⅱ was found in this plant for the first time.
