    Abstract:
    OBJECTIVE: Analysis of the constituents of the essential oil extracted from the Xiaoboju, one of commercial breed came from the flowers of the Chrysanthemum morifolium, processed by the aeration-desiccation and desiccation after the sulfur-bumin fumigation, and to provide scientific basis for quality control. METHOD: The essential oil was 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 aeration dried sample and the dried sample after sulfur-burnin fumigation, 216 and 211 components were detected, among them fifty and six-five components were identified, which were composed of 73.21% and 82.32% of the total essential oil, respectively. CONCLUSION: The yield of the essential oil extracted from the aeration dried sample was 3.50%, and that from the dried sample after sulfur-bumin fumigation was 4.22%. The latter is 1.2 times higher than the former. The components of the essential oil of both samples are mostly monoterpenoids and secondly sesquiterpenoids compounds, but there are marked differences between the compounds contained in the two samples. Therefore, the processing of flowers of the C. morifolium should be strictly controlled and standardized.
