摘 要 ：目的:分析我国浙江省国家杭白菊GAP基地微波加工杭白菊和蒸制杭白菊的挥发油成分,为其质量评价提供科学依据。方法:采用水蒸气蒸馏法提取两种炮制品杭白菊挥发油,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:从微波加工杭白菊挥发油中检出119个色谱峰,鉴定了50个化合物,占总挥发油量的67.89%;从蒸制杭白菊挥发油中检出175个色谱峰,鉴定了55个化合物,占总挥发油量的63.64%。结论:微波加工杭白菊挥发油收率为0.40%,蒸制杭白菊挥发油收率为0.19%,两者相差近2.1倍;两者挥发油组成基本相同,唯各化合物含量有一定差异。采用微波干燥技术加工杭白菊,可尽量多地保留了原形挥发油化学成分;与传统的蒸制加工方法比较,大大改善了菊花的等级和质量。

Abstract:Objective: Analysis of the constituents of the essential oil extracted from the flowers of the Chrysanthemum morifolium processed by the microwave-airflow and the calefaction after steam process from the State Chrysanthemum GAP bases in Zhejiang Province 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 microwave-airflow dried sample and the calefactively dried sample after steam process,119 and 175 components were detected,among them fifty and fifty-five components were identified,which were composed of 67.89% and 63.64% of the total essential oil,respectively.Conclusion: The yield of the essential oil extracted from the microwave-airflow dried sample was 0.40%,and that from the calefactively dried sample after steam process was 0.19%.The former is 2.1 times higher than the latter.The components of the essential oil are similar and there are differences between the content of corresponding compounds in the two samples.The results showed that application of microwave-airflow combined drying technology remained original and essential constituents.The production benefit was improved greatly.The grade and quality of C.morifolium enhanced,and it‘s market selling price was increased compared to the traditional drying calefaction after steam process.
