摘　　要：目的：采用气质联用法（GC-MS）对刺山柑（Capparis spinosa）果实的化学成分进行分析。方法野西瓜药材经粉碎破壳、70％乙醇回流提取、石油醚（沸程60～90℃）萃取后，采用VF-5ms石英毛细管柱（30 m ×0．25 mm ，0．25μm）进行气相色谱分析；柱温从80℃开始，保持2 min ，以15℃／min的速度升到300℃，并保持10 min ，气化温度为250℃；载气为高纯度氦气，流量为1．0 ml／min ；质谱检测器为 EI离子源，电子能量70 eV ，离子源温度200℃，分流比30∶1，进样量为1．0μl。各成分的相对含量分析应用色谱峰面积归一法。结果共检测出53个峰，确认出其中48种成分，含量较高的物质有棕榈酸21．82％，硬脂酸7．49％，油酸42．93％，甘油单油酸酯2．39％，维生素E 1．67％等。化合物的类型主要为饱和脂肪酸酯、不饱和脂肪酸和烃类化合物。结论通过气质联用技术，为鉴定野西瓜果实中的化学成分建立起了一种快速、准确、灵敏的分析方法。Objective To analyze the chemical constituents in fruits of Capparis spinosa by GC-MS analysis .Methods The compounds were extracted from Capparis spinosa by 70% ethanol after smash .After extraction by petroleum ether （boil-ing range was from 60 to 90 ℃） ,the compounds were analyzed by gas chromatography with a VF-5ms capillary column .The column was heated up from 80 ℃ to 300 ℃ ,15 ℃/min ,then maintained for 10 minutes ,vaporization temperature was 250 ℃ , carrier gas was Helium and the flow rate was 1 ml/min .The detection was carried out by mass spectrometry using electron im-pact ion source with 70 eV ionization voltages .The ion source temperature was 200 ℃ and split ratio was 30∶1 .The injection volume was 1 .0 μl .The content of the compounds was determined with peak area normalization method .Results 53 chroma-tographically peaks were separated and 48 chemical constituents were identified including hexadecanoic acid （21 .82% ） ,octade-canoic acid （7 .49% ） ,oleinic acid （42 .93% ） and monoolein （2 .39% ） .These chemical constituents were mainly saturated fatty acid ester ,unsaturated fatty acid ester and alkanes .Conclusion The method is rapid ,accurate and sensitive with the usage of GC-MS ,which could be used to identify main chemical constituents of Capparis spinosa in fruit .
