Nicotine, commonly known as nicotine, is a pyridine-type alkaloid. It exists in tobacco economic plants and is an important component of tobacco and cigarette smoke and a quality control index for cigarettes. The content of nicotine in essential oils for cigarettes varies greatly due to their different formulations. The methods for determining nicotine mainly include gas chromatography, liquid chromatography, gas chromatography-mass spectrometry and spectrophotometry. Gas chromatography has the characteristics of high selectivity, high efficiency, high sensitivity, fast analysis speed and low cost in chemical analysis. It has become one of the necessary instruments in analytical laboratories and is widely used. In this paper, a method for the determination of nicotine content in essential oils and fragrances of tobacco by gas chromatography was established, which aims to quickly and accurately determine the nicotine content in essential oils and fragrances of tobacco, provide data reference for its production and formula research, and can effectively monitor the nicotine content.
