Abstract: The essential oils of fresh flowers and manufactured goods of Chrysanthemum cultivar Dendrathema grandiflorum ‘Xiao Huang Ju were extracted by the simultaneous distillation extraction method， then detected by gas chromatography coupled of mass spectrum. The results were as follows: (1) Seventysix and eightyeight components were respectively identified from the fresh flowers and manufactured goods of ‘Xiao Huang Ju， with monterpenes， sesquiterpenes and their oxygenous derivatives being the major chemical components; (2) Sixtytwo mutual chemical components were identified， with eucalyptol， camphor， verbenol acetate， hexamethylbenzene and so on at high content level. (3) The compounds in essential oils of the fresh flowers which were at least ten times greater than those in essential oils of manufactured goods were camphene， βphellandrene， αphellandrene， (E)ocimene， (Z)ocimene， bicyclo［222］oct5en2one， alloocimene， Dverbenone， safranal， hexamethylbenzene; (4) Fourteen components were only identified from the essential oils of fresh flowers， such as αthujenal， αfenchene， copaene and so on. (5) The relative contents of 6methyl5hepten2one， αzingiberene， βsesquiphellandrene， αcitral， palmitic acid， αcurcumene， (E)limonene oxide， αbisabol and so on in essential oils of manufactured goods were much more than those of fresh flower. (6) Twentysix specific components were only identified from the manufactured goods， including thymol， benzeneacetaldehyde， αterpineol， γcadinene and so on. The results revealed the chemical characteristics of aroma of ‘Xiao Huang Ju， which can be used as the reference during its cultivating， processing and tasting.
