目的:分析蕲艾及不同产地艾叶挥发油成分,为不同产地艾叶及其挥发油的品质评价提供参考依据.方法:采用水蒸气蒸馏法提取艾叶中挥发油,GC-MS联用技术分析鉴定艾叶中挥发油成分,经面积归一化法计算各产地挥发油中各成分相对百分含量,并通过化学计量法主成分分析对蕲艾及不同产地艾叶挥发油成分含量进行分析.结果:共鉴定出155个成分,主要为酮类、烯类、醇类化合物,不同产地艾叶挥发性成分有一定差异,其中湖北蕲春产的艾叶品质最好.结论:经综合分析湖北蕲春艾叶挥发油较其他产地艾叶挥发油品质更优,同一产地艾叶挥发油也存在差异,应进一步区分不同品种艾叶.“,”Objective:To analyze the components of volatile oil in artemisiae argyi folium from different habitats to provide refer-ence for the quality evaluation in artemisiae argyi folium from different areas. Methods:The volatile oil of artemisiae argyi folium was extracted by steam distillation,and the components of volatile oil were analyzed and identified by GC-MS. The relative percentage of each component of volatile oil in artemisiae argyi folium from different habitats was calculated by area normalization method. The com-ponent contents of volatile oil in artemisiae argyi folium produced in Qichun and some other areas were analyzed by stechiometry. Re-sults:A total of 155 components were identified,mainly including compounds of ketones,olefins and alcohols,and the volatile compo-nents of artemisiae argyi folium from different areas were different. The quality of artemisiae argyi folium produced in Qichun was the best. Conclusion:The quality of volatile oil in artemisiae argyi folium produced in Qichun Hubei is better than that produced in other areas. The components of volatile oil in artemisiae argyi folium in the same habitat are also different. The different varieties of artemisi-ae argyi folium need to be further distinguished.
