Study on Chemical Constituents of Volatile Oil fromCallicarpalongissima(Hemsl.)Merr.

The chemical constituents of volatile oils obtained from the leaves and flowers of Callicarpalongissima(Hemsl.)Merr.in Guangxi were analyzed.The volatile oils were extracted from fresh leaves and flowers of Callicarpalongissima(Hemsl.)Merr.by steam distillation and identified by GC-MS.The relative content of each component was determined by area normalization method.The oil yields of the leaves and flowers were 4.51%and 2.79%respectively.Twenty eight components counting to 76.24% of the total oil of leaves were identified,while 20 components counting to 85.25% of the total oil of flowers were identified.The main component of both volatile oils wasα-bisabolol.There were differences in chemical constituents and their contents between leaves and flowers oil.The results can provide a scientific basis for rational use of the Callicarpalongissima(Hemsl.)Merr.and development of a new natural essential oil.
