GC-MS分析重要非挥发性有机酸在烟叶生长过程中的变化
Analysis on Changes of Key Nonvolatile Organic Acids in Tobacco Leaves during Its Growth by Gas Chromatography-Mass Spectrometry
摘要
Abstract
[Objective] The changes of nonvolatile organic acids in tobacco leaves during its growth were studied. [Method] By using the coupling technique of N-methyl-N-trimethylsilytrifluoroacetamide (MSTFA) derivatization-gas-chromatography-mass spectrometry, 11 kinds of key were analyzed through the combination of standard sample and mass spectrum. [ Result] The determination on analyzing index of the method for 6 nonvolatile organic acids with the standard sample showed a good average recovery, with the recovery of 85.4% - 102. 1% and the relative standard deviations (RSD) less than 7.0%. [Conclusion] The method had the simple and convenient, rapid, accurate and other characteristics and was applicable to the determination of the nonvolatile organic acids in tobacco leaves. When the method was applied to determine the changes of nonvolatile organic acids in tobacco leaves during its growth, the change curves of 11 key nonvolatile organic acids in tobacco leaves during its growth was obtained.关键词
