中文摘要：

采用微波辅助提取-GC／MS联用分析苍耳子中的油脂成分。以V（环已烷）：V（丙酮）=1：1为提取溶剂，优化了微波辅助提取的条件。以正二十烷为内标，鉴定出了13种油脂成分，各组分相对保留时间的相对标准偏差（RSD）小于0．15％，相对峰面积的RSD〈3．0％。对不同批次以及不同产地的苍耳子样品进行了对比研究。该方法可用于苍耳子的鉴定和质量控制。

英文摘要：

In this paper, the components of fatty oil in Fructus Xanthii were studied using microwave-assisted extraction （MAE） coupled with GC-MS. A mixed solvent of hexamethylene and acetone （1：1 ） was used as extracted solvent. The MAE conditions were optimized, n-docosane was used as the internal standard. 13 compounds were identi- fied. The relative standard deviations （RSDs） of relative retention time and relative peak area of chromatogram for the components were less than 0.15% and 3.0%, respectively. The samples from different batches and different habitats were also studied. The method is simple and fast. It could be used for discrimination and the quality control of Fructus Xanthii.
