【摘要】:采用Hi-Plex钙型强阳离子交换柱,以超纯水为流动相、示差折光仪为检测器,在进样量15μL、流速0.4mL/min、柱温80℃的条件下建立了高效液相色谱法同时测定烟草中的果糖、葡萄糖、麦芽糖、蔗糖和甘油、丙二醇、山梨醇的方法。结果表明,该方法检测限、回收率、相对标准偏差分别在1.5~2.0 mg/L、97%~108%、0.89%~1.39%。同时,利用该方法对13种国内外品牌卷烟进行分析,结果发现所有卷烟样品中均检出了丙二醇和果糖、葡萄糖、麦芽糖、蔗糖,而仅在中国产卷烟1和C牌号进口卷烟中检出丙三醇的存在,表明大部分卷烟基本上不用甘油作保润剂。同时发现进口卷烟不同价位间所使用保润剂比例不同,其配方保润剂的设计思路可能充分考虑了烟叶类型的差异,值得深入探讨。
