The components were quantitatively determined with normalization method, and were identified with GC-MS.41 components were identified, which took up 72.73% of the essential oils.The main components of essential oils were 4-methyl-1-(1-methylethyl)-3-cyclohexen-1-ol(14.369%), crotonic acid, 2,2-dimethyl-butanoic acid, 1-methyl-3-(1-methylethyl)-benzene, (1s-endo)-1,7,7-trimethyl-bicyclo[2,2,1]heptan-2-ol, trans-1-methyl-4-(1-methylethyl)-2-cyclohexen-1-ol, alpha-cadinol and alpha,alpha,4-trimethyl-3-cyclohexene-1-methanol.
