| 摘 要： | 采用超声辅助液液萃取法(ULLE)提取某品牌烟用香精成分,GC-MS对其进行分析,研究了不同萃取剂、萃取时间和萃取温度对分析结果的影响,初步确定了最佳条件为:以二氯甲烷为萃取剂,饱和NaCl溶液作水相,室温下超声萃取5 min.又分别与同时蒸馏萃取法(SDE)和传统的液液萃取法(LLE)作以比较,对ULLE法和SDE法鉴定出的化学成分、重现性和定量值进行了对比.结果表明:超声辅助液液萃取具有操作简便、快速、节能、萃取效率高、重现性好等特点,适合于烟用香精成分的提取. |

| Abstract: | Ultrasound-assisted liquid-iquid extraction(ULLE) was used to extract the components of tobacco flavor,and the components were analysed by GC-MS.Effects of different extracting solvent,time and temperatures on the results were studied.The optimal extracting conditions are established elementarily as follows: extracting solvent is CH2Cl2;saturated NaCl solution is used as water phase; ultrasound extracting time is 5 min at room temperature.Compared with simultaneous distillation extraction and liquid-liquid extraction,the ULLE has the characteristic of convenience,rapidity,less energy,high extraction efficiency and good repeatability.All the results indicate that the method is suitable for the extraction of components of tobacco flavor. |
| Keywords: | Tobacco flavor Ultrasound-assisted extraction Liquid-liquid extraction Simultaneous distillation extraction |
