【摘要】 目的:分析通风晾干品和硫磺熏制品小亳菊的挥发油成分,为其质量评价提供科学依据。方法:采用水蒸气蒸馏法提取2种小亳菊挥发油,用GC毛细管色谱柱进行分析,归一化法测定其相对含量,GC-MS鉴定化学成分。结果:从通风晾干品小亳菊挥发油中检出216个色谱峰,鉴定了50个化合物,占挥发油总量的73.21%;从硫磺熏制品小亳菊挥发油中检出211个色谱峰,鉴定了65个化合物,占挥发油总量的82.32%。结论:通风干燥晾干品小亳菊挥发油收率为3.50%,硫磺熏制品小亳菊挥发油收率为4.22%,两者相差近1.2倍;两者挥发油组成皆以单萜类化合物为特征性成分,倍半萜类化合物为次要成分,但所含化合物有很大的差异。菊花的硫磺熏制加工过程应严格控制和规范化。更多还原

【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-burnin 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-burnin 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.更多还原
