				        	AIM: To isolate and identify triterpenes from inflorescence of Cremanthodium potaninii C.Winkl,collected from Qinghai province.METHODS: The triterpenes were isolated by column chromatography and their structures were elucidated through NMR.RESULTS: Seven triterpenes were isolated and identified as ?-amyrin(I),Taraxast-20(30)-ene-3?,16?-diol-3-O-palmitate(II),olean-12-en-3?,16?-diol-3-O-palmitate(III),Olean-12-en-3?,11?,16?-triol-3-palmitate(IV),lup-3?,16?-diol-3-O-palmitate(V),lup-3?,16?,28-triol-3-O-palmitate(VI),16?-hydroxypseudo tarsxasterol-3-O-palmitate(VII).CONCLUSION: All these compounds are obtained from Cremanthodium potaninii C.Winkl for the first time.
