摘　　要：利用水蒸气蒸馏法提取苦刺花挥发油,采用气相色谱-质谱(Gas chromatography-mass spectrometry,GC-MS)联用技术对相似度超过85%化学成分进行分离和鉴定,并用峰面积归一化法确定各组分的相对含量。结果共鉴定出45个化合物,占总组分含量的82.11%,其主要成分为棕榈酸(11.98%)、棕榈酸甲酯(11.17%)、亚油酸甲酯(10.82%)、亚油酸(8.42%)、亚麻酸甲酯(8.01%)、正二十九烷(4.44%)、正二十四烷(4.01%)、硬脂酸(3.58%)、硬脂酸甲酯(3.51%)、亚麻酸乙酯(2.61%)等。Volatile oil from Sophora davidii Skeels was extracted via steam distillation. GC-MS was used to analyze the chemical composition of volatile oil and peak area normalization method was used for quantification. Totally 45 compounds were separated and identified, mostly including palmitic acid （11.98%）, methyl hexadecanoate （11.17%）, methyl linoleate （10.82%）, linolic acid （8.42%）, methyl linolenate （8.01%）, nonacosane （4.44%）, octacosane （4.01%）, stearic acid （3.58%）, methyl stearate （3.51%）, ethyl linolenate（2.61%）.
