| Popis: | Bioactive molecules from fruits of four varieties of Prunus persica at different stages of ripening (green, small orange, red) were studied. For example, contents on polyphenols (20.36mg GAE/g FW) and flavonoids (0.764mg RE/g FW) were high and varied according variety. The antioxidant activity, using four different tests (DPPH radical scavenging activity, reducing power, β carotene bleaching system and TBARS assay) showed that the variety Chatos exhibited the highest antioxidant activity comparing with others varieties. The antibacterial activity of Prunus persica varieties studied seems to be more sensitive against Staphylococcus aureus and Listeria monocytogenes. The capacity of peach DMSO extracts to inhibit Candida albicans growth was more pronounced, especially, in the presence of Chatos DMSO extract. Enzymes inhibition gives results which correlate with polyphenols, flavonoids and condensed tannins contents, and so, confirm the fascinating bioactivity of this fruit. |
