[Analysis of the chemical constituents of essential oil from the leaves of Callicarpa integerrima].

To analyze the compositions of the essential oil from the leaves of Callicarpa integerrima. GC-MS method was used. 42 chemical constituents, accounting for 97.62% of total content were identified. The main components were beta-caryophyllene (33.74%), Elixene (12.86%), tau-Cadinene (9.57%) and (-) -Spathulenol (8.99%). Besides, some sesquiterpenes and their oxides, such as Copaene (4.21%), Globulol (3.81%), alpha-Caryophyllene (2.48%), 2-Naphthalenemethanol, decahydro-alpha, alpha, 4a-trimethyl-8-methylene-[2R-(2alpha, 4aalpha, 8alphabeta)]-(2.37%) and 1,6-Cyclodecadiene (2.24%) had also relatively high contents.
