UPLC combined with QTOF/MS is a powerful analytical method for characterizing infusions and alcoholic extracts from myrtle leaves. Several compounds such as gallic acid and galloyl derivatives, ellagic acid and derivatives, hexahydroxydiphenolyl and derivatives, flavonoids, lignans, and gallomyrtucommulones were characterized. Flavonoids, ellagic acid and its derivatives and gallic acid and its derivatives formed the major fractions. In terms of individual compounds, cornusiin C, myricetin-3-O- rhamnoside, gallomyrtucommulone C, myricetin galloyl hexoside, and myricetin galactoside presented the highest percentages in both extracts.
