Exposomic Biomonitoring of Polyphenols by Non-Targeted Analysis and Suspect Screening

Analytical Chemistry, 2023
Polyphenols, prevalent in plants and fungi, are investigated intensively in nutritional and clinical settings because of their beneficial bioactive properties. Due to their complexity, analysis with untargeted approaches is favorable, which typically use high-resolution mass spectrometry (HRMS) rather than low-resolution mass spectrometry (LRMS). Here,
