超声辅助液液萃取-气相色谱-质谱指纹图谱应用于烟用香精香料的检测
Application of GC-MS Fingerprint Atlas to Determination of Tobacco Essence and Flavor with Ultrasound Assisted Liquid-Liquid Extraction
摘 要
采用超声辅助液液萃取-气相色谱-质谱法,建立了烟用香精香料的指纹图谱。以二氯甲烷-乙醇(9+1)混合溶液为萃取溶剂,饱和氯化钠溶液为水相,超声萃取10 min,对1187号烟用香精香料样品进样检测。共检出了25个组分,对其中的23个组分进行了定性。11个批次的样品色谱图显示了较高的相似性,并运用主成分分析法(PCA)区分了添加其它香精香料的掺兑样品。方法可以用于考察烟用香精香料的质量。

Abstract
The chromatographic fingerprint atlas of tobacco essence and flavor were established by GC-MS with ultrasonic liquid-liquid extraction (ULLE). A mixture of CH2Cl2 and CH3CH2OH (9+1) was used as extraction solvent and saturated NaCl solution was used as aqueous phase. Time taken for ultrasonic extraction was 10 min. Sample 1187 of tobacco essence and flavor was taken for analysis. Totally 25 compounds were separated, among which 23 components were identified. Good similarities between the chromatographic fingerprint atlases of the 11 batches of samples were obtained. Two samples mixed with other kind of flavor components were obviously distinguished from the 11 batches of samples of 1187 by principle component analysis (PCA). A comprehensive inspection on the quality of tobacco essence and flavor was attained by the proposed method.
