N2 - Purpose: To study the composition of extracts of Ginja cherries stems and leaves obtained after extraction using different solvents and to evaluate their antioxidant activities. Stems and leaves are by-products of the Ginjinha cherry liquor production; extracting valuable compounds with the most appropriate solvent would valorise these wastes. Method The extraction was performed using different solvents (acetone, ethanol, methanol, ethyl acetate, water, 2-propanol); liquid chromatography-electro spray ionization-mass spectrometry (LC-ESI/MS) was utilized to identify the predominant phenolic acids and flavonoids present in the resulting extracts. The Total Phenolic Content was determined with the Folin-Ciocolteau method. The antioxidant activity was also tested using the ABTS + essay. Results:Stems extracts showed a higher concentration in polyphenols than those from leaves. The solvent affected remarkably the extracts compositions: considering the polyphenols content ethanol and water gave the best results for stems and leaves, respectively. A good correlation was established between the antioxidant activity of the extracts and their polyphenolic composition.
