The chemical constituents of fragrance volatile and essential oil of litsea cubeba root have been investigated in this work. 71 components of the fragrance volatile were separated and identified by GC-MS. covering 98.62% of the total peak area; 37 components of essential oil were separated and identified, occupying 97.46% of the total peak area. Then 44 of the former, (84.50%), and 24 the of latter, (93.42%) were further identified by dual column temperature-programmed retention indexes with corresponding authentic samples. The main constituents of the fragrance volatile of litsea cubeba root were naphthalene (12.64%);α-pinene(10.08%) ,citronellal(9.66%), limon-ene(9.5%), β-pinene(8.89%), camphor(6.33%), isopulegol(5.6%), and those of the essential oil were citronellal(58.86%), citronellol(8.80%), limonene(5.43%) and aaaaaaaaaaa-pinene(4.32%).
