Metabolomic Profile of Vaccinium corymbosum Leaves: Exploiting Diversity Among Ten Different Cultivars

Blueberry (Vaccinium corymbosum) leaves are often discarded as agricultural by-products despite their potential abundance in bioactive compounds. However, comprehensive knowledge of their phytochemical profile remains limited, especially at the cultivar level. To address this gap, this study performed untargeted metabolomic profiling of blueberry leaves from ten cultivars using UHPLC-QTOF MS. Metabolites were annotated using high-resolution mass spectrometry and MS/MS fragmentation patterns....
