This publication reports the first known use of gas chromatography-tandem mass spectrometry for the quantitation of five minor tobacco alkaloids (nornicotine, myosmine, anabasine, anatabine, and isonicoteine) in various tobacco samples. A summary of the concentrations of these minor alkaloid levels in the filler from 50 popular cigarette brands were found to be 659-986 μg/g nornicotine, 8.64-17.3 μg/g myosmine, 127-185 μg/g anabasine, 927-1390 μg/g anatabine, and 23.4-45.5 μg/g isonicoteine. Levels of minor alkaloids found in reference cigarettes (1R5F, 2R4F, 3R4F, CM4, and CM6) as well as burley, flue-cured, oriental, reconstituted, and Nicotiana rustica and Nicotiana glauca tobacco types are also reported. Quantitation of the minor tobacco alkaloids is important because the alkaloids have been shown to be precursors of carcinogenic tobacco specific N'-nitrosamines.

Cigarette brand variant names and characteristics such as the taste and feel of the smoke can mislead consumers into believing some products are less harmful. We assessed the characteristics of three common cigarette variants sold in Australia, "gold", "blue" and "red", to determine which characteristics differed by color, and which affected tar, nicotine and carbon monoxide (TNCO) yields. TNCO yields, physical parameters, expanded tobacco and filter ventilation were measured in cigarette color variants from eight brands.

Despite the diverse industrial applications and health benefits of plant gums, significant variations in quality among different types remain underexplored. This study investigates the differences in antioxidant activity, mineral elements, and metabolic profiles among peach, acacia, and karaya gums. Our findings reveal significant differences in total phenol content, with peach gum exhibiting the highest (20.

Cigarette smoking remains an enormous public health problem causing millions of preventable deaths annually worldwide. Although safe and efficient smoking cessation pharmacotherapies such as nicotine replacement products and the medications varenicline and bupropion are available, long-term abstinence rates remain low and new approaches to help smokers successfully quit smoking are needed. In recent years, electronic nicotine delivery systems such as e-cigarettes and heated-tobacco products, and novel smokeless nicotine delivery products like nicotine pouches have gained widespread popularity.

Background: Low temperatures disrupt nitrogen metabolism in tobacco, resulting in lower nicotine content in the leaves. 24-epibrassinolide (EBR) is a widely used plant growth regulator known for its roles in enhancing cold tolerance and nitrogen metabolism. Nevertheless, it remains unclear whether EBR enhances leaf nicotine content under low temperature conditions during the mature stage of flue-cured tobacco.

Human exposure to volatile organic compounds (VOCs) poses significant health risks, contributing to cardiovascular disease, pulmonary disease, and cancer. Measurement of VOC metabolites (VOCm) in urine by liquid chromatography-mass spectrometry (LC-MS) is a preferred method for VOCm analysis; however, existing methods encounter challenges related to sensitivity, throughput, and analyte coverage. In addition to VOCm, the measurement of tobacco alkaloids (TAm) is critical to account for tobacco use in population-based studies.
