加热不燃烧卷烟烟草材料中1,2-丙二醇、丙三醇和烟碱的测定

Determination of 1,2-propylene Glycol, Glycerol and Nicotine of Tobacco Materials in Heat-not-burn Cigarettes

摘要

摘要: 为准确测定加热不燃烧卷烟烟草材料中1，2-丙二醇、丙三醇和烟碱的含量，以1，4-丁二醇和2-甲基喹啉为内标建立了同时测定加热不燃烧卷烟烟草材料中1，2-丙二醇、丙三醇和烟碱的气相色谱-氢火焰离子化法（GC-FID），并测定了5个不同品牌的12个烟草材料样品。结果表明，该方法的检出限和定量限分别在0.02~0.22 mg/g和0.06~0.74 mg/g；回收率84.74%~98.81%；日内、日间精密度在0.15%~0.86%。所测样品中1，2-丙二醇、丙三醇和烟碱的含量分别在0~82.45 mg/g、116.31~204.98 mg/g和7.06~15.26 mg/g。所有样品中均检出丙三醇和烟碱。国内样品中1，2-丙二醇的含量比国外样品高。该方法前处理简单、灵敏度和准确度高，可满足不同加热不燃烧卷烟烟草材料中1，2-丙二醇、丙三醇和烟碱的检测要求。

Abstract: A gas chromatography-flame ionization (GC-FID) method was developed for determination of 1,2-propylene glycol, glycerol and nicotine of tobacco materials in heat-not-burn cigarettes by using 1,4-butanediol and quinaldine as internal standards. Twelve tobacco material samples of five different brands were determined by the method. The results showed that:1) The limit of detection and limit of quantitation were 0.02-0.22 mg/g and 0.06-0.74 mg/g, respectively; the recoveries were 84.74%-98.81%, and intra-day and inter-day precisions were 0.15%-0.86%. 2) The contents of 1,2-propylene glycol, glycerol and nicotine in the samples ranged from 0-82.45,116.31-204.98, and 7.06-15.26 mg/g, respectively. 3) Glycerol and nicotine were detected in all samples. 4) The content of 1,2-propylene glycol in domestic samples was higher than that in foreign samples. This method was easy, sensitive and accurate, and was suitable for determination of 1,2-propylene glycol, glycerol and nicotine of tobacco materials in heat-not-burn cigarettes.
