Abstract
Objective: To analyze the chemical components of the essential oil extracted from two cultivars of Chrysanthemum morifolium( C. morifolium Ramat Hongxinjucv. nov. and C. morifolium RamatHuangjucv nov.) cultivated in Jangsu province and provide scientific basis for their quality control. Method:The essential oil of the two cultivars of C. morifolium 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. Result: From the C. morifolium Ramat Hongxinjucv. nov. and C. morifolium RamatHuangjucv nov.,217 and 167chromatographic peaks were detected,among them 73 and 64 components were identified,which were composed of 67. 36% and 62. 75% of the total essential oil,respectively. Conclusion: 2-carene,cis-ocimene, gamma.-terpinene, camphor, borneoll, trans(. beta.)-caryophyllene, zingiberene,farnesene,caryophyllene oxide and junipercamphor were identified in the essential oil of the two cultivars C.morifolium Ramat Hongxinju cv. nov. and C. morifolium Ramat Huangju cv nov.. Among them,the amounts of junipercamphor were the most which were composed of 12. 64% and 10. 87% of the total essential oil,respectively. Trans(. beta.)-caryophyllene is the second,which were composed of 6. 45% and 4. 38% of the total essential oil,respectively. There are marked differences in the compounds between the two samples. The results provide scientific basis for quality control of Chrysanthemum morifolium which are cultivated in Jangsu province.
