| 摘 要： | 采用水蒸气蒸馏法对荠菜叶挥发油进行了提取。通过毛细管气相色谱—质谱联用法分离并鉴定了其化学成分,用气相色谱面积归一化法测定了各成分的相对百分含量,共分离确定了其中12种化合物,所鉴定化合物的含量占全油的65.62%,主要化学成分为：L-胍基琥珀酰亚胺（21.28%）、植醇（18%）、植酮（9.6%）、油酸（4.71%）、棕榈酸（3.97%）等。

| Abstract: | Steam distillation device was used for extracting the volatile substances of leaves from Capsella bursa - pastoris L.. 12 chemical components were identified by gas chromatography- mass spectrometry （GC - MS）. The identified compounds were up to 65.62% of the total volatile s~. 1 - Guanidinosuceinimide （21.28 % ）, Phytol （ 18 % ）, 2 - Pentadecanone, 6,10,14 - trimethyl - （9.6 % ）, Oleic Acid （4.71% ）, and the n- Hexadecanoic acid were the major concentrations of the volatile components. |
