不同炮制品怀小白菊挥发油成分的GC-MS分析

目的:分析我国河南菊花GAP基地自然送风干燥怀小白菊和蒸制怀小白菊的挥发油成分,为其质量评价提供科学依据。方法:采用水蒸气蒸馏法提取2种炮制品怀小白菊挥发油,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:从自然送风干燥怀小白菊挥发油中检出90个色谱峰,鉴定了69个化合物,占总挥发油量的90.56%;从蒸制怀小白菊挥发油中检出89个色谱峰,鉴定了53个化合物,占总挥发油量的93.00%。结论:自然送风干燥怀小白菊挥发油收率为0.260%,蒸制怀小白菊挥发油收率为0.108%,两者相差近1.5倍;两者挥发油组成有一定区别。

GC-MS analysis of essential oil of the flower of the Chrysanthemum morifolium by the different processing methods

Objective: Analysis of the constituents of the essential oil extracted from the flowers of the Chrysanthemum morifolium processed by two different methods in the chrysanthemum GAP Base of China in Henan Province and to provide scientific basis for quality control.Method: The essential oils 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 air flowing dried sample and the braised sample,ninety and eighty-nine components were detected,among them sixty-nine and fifty-three components were identified,which were composed of 90.56% and 93.00% of the total essential oil,respectively.Conclusion: The yield of the essential oil extracted from the air flowing dried sample was 0.260%,and that from the braised sample was 0.108%.The former is 1.5 times higher than the latter.There are differences between the constitutions of the two samples.
