气相色谱-质谱法测定金铁锁根挥发油化学成分

GC-MS Determination of Chemical Components in Volatile Oil of Psammosilene Tunicoides

采用水蒸气蒸馏法提取金铁锁根挥发油,毛细管柱气相色谱-质谱法测定了金铁锁根挥发油的化学成分,用面积归一化法定量。分离出71个峰,鉴定了其中的33种化学成分,占挥发油的89.62%,其主要成分为十六烷酸(19.25 %)、3-二十八烷酮(15.93%)、水杨酸甲酯(9.73%)、9,12-十八二烯酸(8.95%)、2-萘基苯基胺(7.91%)、9-十八碳炔酸(6.50 %)、二十五烷(4.26%)、十五烷基醇(3.81%)、二十四烷(3.47%)、二十三烷(2.41%)等。

The volatile oil in psammosilene tunicoides was extracted by steam distillation, and the chemical components in volatile oil were identified by capillary column GC-MS. The relative contents （in %） of the components were determined using the method of normalization. Seventy-one chromatographic peaks were separated and among which 33 components were identified amounting to 89. 62% of the total. Contents of the main compounds were found as follows： hexadecanoic acid （19. 25%）, 3-oetacosaneone （15. 93%）, methyl salicylate （9. 73%）, 9, 12-octadecadienoic acid （8. 95%）, 2-naphthylphenylamine （7. 91%）, 9-octadecynoic acid （6. 50%）, pentacosane （4. 26%）, pentadeeanoie acid （3. 81%）, tetracosane （3.47%）, octacosane （2. 41%） and etc.
