The results showed that twelve fragrant components were identified. Among the fragrant components, six terpenes were account for 63.74% of the total content, the alcohol, aldehyde, lipid and furan were account for 22.48%, 0.48%, 4.68% and 4.44%, respectively.Nine compounds were identified with the match degree above 90% and relative amount of 93.46%.The main aromas were cis-3-nonene-1-ol, (-)-Alpha-Cubeb oil terpenes and trans-caryophyllene.
