| 摘 要： | 使用超高效液相色谱-电喷雾串联四极杆质谱(UPLC-ESI-MS/MS)在多反应离子监测(MRM)模式下分离鉴定了烟草中7种潜香物质。烟样经甲醇提取,XAD-2柱分离纯化,选择中性丢失162u扫描确定母离子。通过对母离子二级质谱扫描(MS2),并根据m/z192.7、179.2、163.1、134.7、133.2等特征碎片离子峰分析结果确定了7种潜香型物质,分别为熊果苷、香豆酸-葡萄糖苷、香豆素奎尼酸、新绿原酸、绿原酸、葡萄糖基阿魏酸、3-氧化紫罗兰醇葡萄糖苷。

| Abstract: | A method for identification of 7 aroma precursors in tobacco was established by using ultra performance liquid chromatography-tandem mass spectrometry interfaced with electro-spray ionization(UPLC-ESI-MS/MS)in the multiple reaction monitoring(MRM)mode.Aroma precursors in tobacco were extracted with methanol,cleaned up with XAD-2 column,then detected and identified by ESI-MS/MS with the neutral loss method.According to the characteristic product ions of m/z 192.7,179.2,163.1,134.7,133.2 acquired by product i... |
