摘　　要：目的分析细叶黑三棱挥发油的化学成分。方法采用水蒸气蒸馏法提取细叶黑三棱挥发油,经气相色谱-质谱联用(GC-MS)结合计算机检索对其化学成分进行鉴定,用色谱峰面积归一法确定各化学成分的相对含量。结果从其挥发油中分离出11个色谱峰,鉴定出9种化合物。占挥发油总量的94.978%。结论挥发油主要成分为棕榈酸(33.226%)、亚油酸(14.941%)、邻苯二甲酸双(2-甲氧基)乙酯(13.482%)、邻苯二甲酸双(2-甲基)丙酯(12.382%)。Objective To analyze the chemical compositions of volatile oil from Sparganium stenophyllum. Methods The volatile oil was extracted from Sparganium stenophyllum by steam distillation. Then, the chemical compositions of the volatile oil were separated and identified by GC-MS, and their relative amounts were determined by area normalization method. Results 11 peaks and 9 compounds were separated and identified, accounting about 94. 978% of the total volatile oil . Conclusion The major compounds are as follows： hexadecanoci acid （33. 226% ） ; 9,12 - octadecadienoic acid （ 14. 941% ） ; 1,2 - benzenedicarboxylicaid, bis （2 - methoxy ethyl） ester （ 13. 482 % ） ; 1,2 - benzenedicarboxylicaid, bis （2 - methyl propyl） ester （ 12.382 % ）.
