Comparative Analysis of Volatile Oil in Artemisiae Argyi Folium Produced in Qichun and Some Other Areas by GC-MS / 中国药师

ABSTRACT

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-sultsA 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.
