Determination and source identification of yellow substances in non-water-soluble yellow spots on cigarette paper
摘要
Abstract
[Objective]To investigate the material basis and causes of non-water-soluble yellow spots on cigarette paper.[Methods]Liquid chromatography coupled with a diode array detector(LC-DAD)was used to qualitatively and quantitatively analyze the yellow substances in non-water-soluble yellow spots,and their sources were investigated through the determination of yellow substances in different tobacco materials combined with solvent leaching experiments.[Results]The result showed that the yellow substances in the non-water-soluble spots were soluble in organic solvents such as ethanol but insoluble in water,and their color faded upon sunlight exposure.Such spots can be distinguished by testing their water solubility and light fading behavior.With ethanol as the extraction solvent,vortex extraction was applied to cigarette paper and matrix disruption extraction to tobacco materials,achieving complete extraction of the lipophilic yellow pigments.Based on their retention times and absorption spectral profiles obtained by two-dimensional absorption spectroscopy,the yellow substances in the non-water-soluble spots were identified as lutein and β-carotene.The contents of lutein and β-carotene in eight cigarette paper samples with non-water-soluble yellow spots were determined to be in the range of 1.07～7.00 μg/g and 0.64～13.37 μg/g,respectively.Trace amounts of lutein and β-carotene were also detected in oily spots on cigarette paper caused by ester solvent contamination.Lutein and β-carotene mainly originated from the blended cut tobacco,and their contents in different materials followed the order of cut tobacco>reconstituted tobacco sheet>cut stem.Dichloromethane leaching experiments showed that among these materials,reconstituted tobacco sheet released the largest amount of lipophilic yellow pigments,whereas cut stem exhibited the highest leachable proportion.[Conclusion]The established method can be used for the identification and source tracing of non-water-soluble yellow spots on cigarette paper,providing a reference for the scientific prevention and control of spotted cigarettes.关键词
