摘要
采用同时蒸馏萃取、水蒸气蒸馏、固相微萃取和溶剂萃取法分别提取烟用香精中的挥发性成分,并采用GC和GC/MS进行测定,通过比较色谱指纹图谱中提取特征组分的数目、含量和表征香精指纹性的能力,以及提取方法的重复性,得到其最佳提取方法。结果表明:同时蒸馏萃取法能最大程度提取AB1香精样品的风味成分并具有较好的重复性,可以满足建立指纹图谱的要求。
The volatile components in tobacco flavor were extracted with solvent extraction, simultaneous distillation extraction （SDE）, steam distillation and solid phase micro-extraction respectively, then determined by GC and GC/ MS. The best extraction method was determined by comparing the number and contents of the characteristic portions picked up from the chromatographic fingerprint spectrums, ability for characterizing flavors＇ fingerprint and the repeatability of extraction characterized component fingerprint spectrum methods. The to the utmost results showed that for flavor sample AB1 the SDE was able to with higher repeatability, and well fulfill the requirements for extraet its creating a fingerprint spectrum.
