Phenolic compounds present high antioxidant activity and, therefore, health promoting effects, serving as a type of preventive medicine. Hence, research on the chemical composition of plants with potential antioxidant value is of high interest. Forest cleaning, thinning, and pruning are beneficial activities that help maintaining healthy forests. In addition, they can provide vegetal material as source of valuable bioactive compounds that can have health promoting effects. In this work, the phenolic composition of several trees native to Madeira Archipelago (Portugal) was studied. Specifically, the leaves from Olea europaea ssp. cerasiformis, Ilex per ado ssp. perado, Clethra arborea, and Heberdenia excelsa have been analyzed. The screening of the main phenolic compounds from their methanolic extracts has been carried out using high-performance liquid chromatography with electrospray ionization mass spectrometric detection (HPLC-ESI-MSn). This is the first report on the phenolic composition of these Madeira native species, and more than 100 compounds have been detected and identified or tentatively characterized.
