采用同时蒸馏萃取-气相色谱/质谱分析小茴香的挥发性成分

Study on Volatiles in Foeniculum Vulgare Mill by Gas Chromatrography-mass Spectrometry Combining with Simultaneous Distillation and Solvent Extraction

通过比较精油收率及精油气相色谱分析含有的组分数量,确定同时蒸馏萃取方法提取小茴香挥发性成分较佳条件为乙醚萃取剂,小茴香∶乙醚∶水为10g∶40mL∶100mL,提取时间3h。气质联机分析所提取的挥发油,鉴定出反式茴香脑(7456%)、爱草脑(240%)、葑酮(105%)、茴香醛(351%)、1,8桉树脑(015%)、樟脑(005%)、萜烯类(297%)、香豆素(003%)、十八碳烯酸(018%)等43种化合物,总相对百分含量为8903%。

Through comparing the yields and numbers of potential components on GC for the extracts in several experiment schemes,the optimal parameters of SDE (simultaneous distillation and solvent extraction) of Foeniculum vulgar Mill were determined. The ratio of Foeniculum vulgar Mill to ether as well as water was 10 g∶40 mL∶100 mL and the experimental time was 3 h. Forty-three components constituting 89.03% of the total extract were identified by GC-MS. They were trans-anethole(74.56%), estragole (2.40%), fenchone (1.05%), anisealdehyde (3.51%), eucalyptol (0.15%), camphor (0.05%), terpenes (2.97%), coumarin(0.03%), and octadecenoic acid (0.18%) ect.
