Method for measuring distribution uniformity of cut stems in cigarette

The invention provides a cigarette cut stem rate determination method, which comprises: balancing cigarette cut tobacco in a cigarette sample, crushing to obtain cut tobacco powder, adding a solvent and an internal standard solution, carrying out vortex oscillation extraction to obtain a sample solution, determining the sample solution by using gas chromatography-tandem mass spectrometry, and determining the nicotine content in the sample solution, and determining the cigarette cut stem rate in the cigarette sample according to the linear relationship between the nicotine content and the cigarette cut stem rate. The invention further provides a method for measuring the distribution uniformity of the cut stems in the cigarette. According to the method for measuring the distribution uniformity of the cut stems in the cigarettes, the cut stem rate of the cigarettes is quantitatively studied, the distribution uniformity of the cut stems in the cigarettes can be evaluated, and the method is convenient to operate,
