[Objective] To analyze the compositions of volatile oil from root and velamen of Kalopanax septemlobus(Thunb.) Koidz.,aiming at providing scientific evidence for the development of medicinal value of Kalopanax septemlobus(Thunb.) Koidz..[Method] The volatile compositions were extracted with headspace solid-phase micro-extraction(HS-SPME),and their contents and names were confirmed by GC-MS.[Result] Seventy-seven and eighty-one compounds were separated and identified from the root bark and root of Kalopanax septemlobus(Thunb.) Koidz.respectively,occupying 97.47% and 96.17% of total volatile oil respectively.The major components obtained from root and root bark of Kalopanax septemlobus(Thunb.) Koidz.were found to be similar,such as γ-elemene,trans-β-farnesene,alpha-Guaiene and 2-(1-methyl-ethyl)-5-methyl-phenol,the contents of which in the two materials were not significant different.[Conclusion] The compounds and their relative contents in root and root bark from Kalopanax septemlobus(Thunb.) Koidz.are confirmed in this study,which favors the development of the medicinal value of Kalopanax septemlobus(Thunb.) Koidz..
