OBJECTIVE To analyze and identify the volatile components of Rhodiola quadrifida.METHODS The R.quadrifida sample was extracted by headspace solid phase microextraction(HS-SPME);the volatile components were analyzed and identified by gas chromatography-mass spectrometry(GC/MS);and the relative content of each compound was calculated by area normalization method.RESULTS 75 volatile components were identified from the sample of R.quadrifida,including alkanes,alcohols,olefins,aldehydes,acids,ketones,etc.They respectively accounted for 55.06％,13.34％,2.21％,5.53％,15.72％,6.64％of the volatile components.CONCLUSION The volatile components of R.quadrifida are diverse,which can be conveniently and accurately identified by HS-SPME-GC/MS.
