摘　　要：采用水蒸气蒸馏法提取了艾叶挥发油,用气相色谱-质谱法(GC/MS)对其化学成分进行了分析,比较了6种采集期不同的艾叶挥发油的含量和化学成分.结果表明:6种采集期艾叶中挥发油质量分数分别为0.607%,0.750%,0.953%,0.884%,0.751%,0.680%,鉴定出的化学成分数目依次为29,32,29,27,34和28种,有17种相同的化合物被检出.通过比较艾叶挥发油主要成分,如1,8-桉叶油素、樟脑、龙脑、4-萜烯醇等时发现,6月2日采集的艾叶中的挥发油含量最高,品质最好,6月上旬为艾叶的最佳采收期.To compare and analyze the yield and chemical components of volatile oil from Artermisia argyi Levl. et Vant. gathered in six different growing periods, the volatile oil was extracted by steam distillation and the chemical components was analyzed by GC/MS. The resuhs showed that the mass fraction of the oil yield from 6 different growing periods was 0.607% , 0.750% , 0. 953% , 0. 884, 0. 751% , 0. 680% respectively and 29,32,29,27,34 and 28 components were separated and identified, among which there were 17 are common to all the extractions. An assay of the main components from the volatile oi1（ eucalyptol, camphor, borneol, terpinen-4-ol, etc. ） revealed that the highest yield and the best quality was obtained from those gathered at June 2. Early June might be the best harvest time for Artemisiae argyi Levi. et Vant.
