Predicting Precursor Ions Combined with Fragmentation Pathway for Screening and Identification of Flavan-3-ol Oligomers in Tea (<i>Camellia sinensis</i>. var. <i>assamica</i>)

Flavan-3-ol oligomers (FLOs), including proanthocyanidins (PAs) and theasinensins (TSs), contribute greatly to the flavor and bioactivity of the tea beverage. Ultrahigh-performance liquid chromatography coupled with high-resolution mass spectrometry has been widely used in profiling a wide range of...
