[GC-MS analysis of essential oil of the flower of the Chrysanthemum morifolium by the different processing methods].
OBJECTIVE
Analysis of the constituents of the essential oil extracted from the flowers of the Chrysanthemum morfoliumum processed by two different methods in the chrysanthemum GAP Base of China in Henan Province and to provide scientific basis for quality control.


METHODS
The essential oils were extracted by water-steam distillation and separated by GC capillary column chromatography. The components were quantitatively determined with normalization method, and identified by GC-MS.


RESULTS
From the air flowing dried sample and the braised sample, ninety and eighty-nine components were detected, among them sixty-nine and fifty-three components were identified, which were composed of 90.56% and 93.00% of the total essential oil, respectively.


CONCLUSIONS
The yield of the essential oil extracted from the air flowing dried sample was 0.260%, and that from the braised sample was 0.108%. The former is 1.5 times higher than the latter. There are differences between the constitutions of the two samples.
