Quantification of Total Phenols, Tannins, Anthocyanins Content in Myrtus communis L. and Antioxidant Activity Evaluation in Function of Plant Development Stages and Altitude of Origin Site

Most of the biological properties myrtle (Myrtus communis L.) are linked to antioxidant activity phenolic compounds present in extracts. In this study, content total phenols, tannins, and anthocyanins acidified ethanol extracts berries leaves five cultivars was quantified during whole fruit development. some development stages, (AA) both tissues evaluated with FRAP, ABTS, DPPH, ?-carotene assays, spectroscopic method (EPR). The trend AA leaf berry different among genotypes evaluation assays. general, showed DPPH assay, highest autumn season, while FRAP higher at 120 DAF (days after flowering) corresponding summer season. berries, EPR assays for all 150 210 DAF, assay first stage. Both berry, phenols tannins contents influence depending on used, seem play a minor role. altitude site origin differently affected berry. study potentiality use studied further applications activity.
