[Characterization of chemical components of essential oil from cupitulum of Chrysanthemum morifolium cultivated in Tongxiang city].
OBJECTIVE
To analyze the chemical components of the essential oil extracted from five cultivars' Hangjuhua (Zaoxiaoyangju, Chixiaoyangju, Dayangju, Yizhongdabaiju and Xiaotangju), which were breed came from the Chrysanthemum morifolium Ramat, and provide scientific basis for quality control.


METHODS
The essential oil of five cultivars' Hangjuhua 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 Zaoxiaoyangju, Chixiaoyangju, Dayangju, Yizhongdabaiju and Xiaotangju, 179, 167, 209, 211 and 270 chromatographic peaks were detected, among them 54, 56, 60, 55 and 65 components were identified, which were composed of 73.40%, 64.14%, 65.19%, 53.55% and 62.89% of the total essential oil, respectively.


CONCLUSIONS
The common chemical constituents were juniper camphor, 1, 3, 3-trimethylcyclohex-1-ene-4-carboxaldehyde, borneol, alpha-curcumene, alpha-bisabolol, cis-caryophyllene, benzyl benzoate, methyl beta, beta-dimethylbenzenepropanoic acid ester, 2, 4-decadienal and heneicosane in the essential oil of the five cultivars' Hangjuhua. Among them, juniper camphor is most which were composed of 11.96%, 10.51%, 10.95%, 13.28% and 10.77% of the total essential oil, and methyl beta, beta-dimethylbenzenepropanoic acid ester is second, which were composed of 1.51%, 1.86%, 2.52%, 4.89% and 2.51% of the total essential oil, respectively. There are marked differences in the compounds contained in the five samples. The juniper camphor is a characteristic constituent in the essential oil of Hangjuhua. The resultant data provided the evidences to establish Hangjuhua' cultivars and scientific basis for quality control of Hangjuhua.
