Abstract: The volatile compounds were extracted in the trunk and bark of Kalopanax septemlobus(Thunb.) Koidz. by headspace solid-phase micro-extraction(HS-SPME). Their constituents were analyzed and identified by gas chromatography-mass spectrometry combined with Kovats retention index,and the relative contents were quantified by calculating basing on the peak areas norma-lization method. The results showed that 53 volatile constituents in the trunk and 67 volatile constituents in the bark of K.septemlobus were identified, accounting for 95.91% and 96.60% of the total peak areas, respectively.The main components obtained from trunk and bark were found to be quite similar. γ-elemene(18.59%,14.60%), germacrene d (19.09%,15.79%), trans-β-farnesene (13.94%,16.88%).
