Flavor components in tobacco capsules identified through non‐targeted quantitative analysis

Journal of Mass Spectrometry, 2022
AbstractTobacco flavors increase the attractiveness of a tobacco brand and ultimately promote addiction. Information about what flavor and how much flavor is in flavor capsules can provide an effective way to regulate tobacco flavor. In this study, 128 flavor chemicals were identified and quantified by gas chromatography–mass spectrometry using ...

Non-target UHPLC/MS Analysis of Emerging Contaminants in Water

2015
Contamination of water resources is one of the major problems to be faced for environment preservation and sustainability. Although anti-pollution strategies taken in the last half-century have consistently reduced in surface water the amount and the presence of many recognised contaminants, other potentially hazardous chemicals are being released into

Analysis of ischemic stroke biomarkers based on non-targeted metabolomics

Chinese Journal of Chromatography
Biomarkers for ischemic stroke (IS) are yet to fulfill clinical requirements. This study used non-targeted metabolomics to investigate differential metabolites and metabolic pathways in plasma and brain tissue following IS, with the aim of identifying new potential biomarkers and therapeutic targets. Twelve Tibetan miniature pigs were randomly assigned

������������������������������-Non-targeted metabolomics analysis of emotional tears of human

2021
We hypothesize that different emotional tears (positive or negative emotions) contain distinct substances, which may be the basis of chemosignal for tearing. The present study seeks to address the biochemical story behind emotional tears by non-targeted metabolomics analysis between positive and negative emotional tears of humans and discovering ...
