| 摘 要： | 从两个方面综述了国内外烟草和烟气中烟碱形态及分布的各种研究方法和机理:①通过溶剂提取测得游离烟碱,进而揭示游离烟碱含量与烟草pH值和烟气pH值之间的关系;②直接通过1HNMR得到烟碱的形态分布。还介绍了烟碱形态以及部分其它烟草生物碱形态相关的理论计算、1HNMR测定法以及"有效pH值"概念,并探讨了在"有效pH值"与烟草pH值和烟气pH值之间建立相关关系的可能性及相应方法。

| Abstract: | THE RECENT ADVANCES IN THE RESEARCH METHODS AND MECHANISM OF NICOTINE FORMS AND DISTRIBUTION IN TOBACCO AND TOBACCO SMOKE AT HOME AND ABROAD WERE REVIEWED IN TWO ASPECTS: 1) EXTRACTING AND DETERMINING THE FREE NICOTINE IN TOBACCO OR TOBACCO SMOKE WITH SOLVENT, AND THEN REVEALING THE RELATIONSHIP BETWEEN THE CONTENT OF FREE NICOTINE AND TOBACCO PH (OR TOBACCO SMOKE PH); 2) OBTAINING THE DISTRIBUTION PROFILE OF NICOTINE IN TOBACCO AND TOBACCO SMOKE DIRECTLY FROM ~1?H NMR DETECTION. THE THEORETICAL CALCULATIONS RELEVANT TO THE FORMS OF NICOTINE AND SOME OTHER TOBACCO ALKALOIDS, ~1?H NMR METHOD AND THE CONCEPT OF "EFFECTIVE PH" WERE INTRODUCED. THE POSSIBILITY AND MEANS FOR DEVELOPING THE RELATIONSHIP BETWEEN "EFFECTIVE PH" AND TOBACCO PH OR TOBACCO SMOKE PH WERE ALSO DISCUSSED. |
