Abstract:

To identify the difference of the composition of essential oils extracted using different liquid solvents, cinnamon essential oils were extracted using petroleum ether, n-hexane and chloroform in this study. The optimum extraction condition was found out, and the composition of essential oil was analyzed by using GC-MS. The main conclusions were as follows: the optimum extraction condition was that chloroform was best solvents, cinnamon: chloroform was 1:15(W/V), extraction time 60 min, Extraction count was 3 times; the chemical compositions of essential oils extracted by different extraction liquid solvents in kinds and percentage composition were different, but not significant.
