摘　　要：利用水蒸气蒸馏法提取千针万线草挥发油,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40个化合物,其主要成分为香草醛(21.73%)、香草乙酮(8.86%)、十四碳酰胺(6.97%)、三苯基氧膦(4.58%)、4-羟乙酰基-2-甲氧基苯酚(3.01%)、溴代十八烷(2.74%)、十四碳烯醇乙酸酯(1.57%)、丁香醛(1.28%)、十三酸(1.23%)、异香草醛(1.13%)等。Volatile oil from Stellaria yunnanensis Franch 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 40 compounds were separated and identified, mostly including vanillin（21.73 %）, acetovanillone（8.86 %）, tetradecanamide（6.97 %）, triphenylphosphine oxide（4.58 %）, 4-hydroxyacetyl-2-methoxyphenol（3.01%）, l-bromooctadecane（2.74 %）, 13-tetradecenyl acetate（1.57 %）, 3,5-Dimethoxy-4-hydroxybenzaldehyde（1.28 %）, isovanillin（1.13 %）.
