| Özet |
| The surge in interest in bioactive plant compounds, particularly from grapes (Vitis vinifera L.), has led to this study on phenolic compounds at different ripening stages. Grapes were collected before veraison, at veraison, and during ripening. Phenolic compounds were extracted using 50% acetone and quantified through spectrophotometric assays for total phenolic, flavonoid, flavanol, condensed tannin, and hydrolysable tannin contents. LCMS/MS identified phenolics. Antioxidant activities were assessed via (DPPH), (ABTS), phenanthroline, reducing power, and silver nanoparticle assays. Additionally, anti-tyrosinase activity and photoprotective effects were evaluated. The results indicated that before veraison (BV) stages yielded the highest concentrations of phenolic compounds. The most abundant compounds at the berry veraison stage were catechin (72645.40, Sabel), gallic acid (1130.75, Red Glob), and luteolin (164.44, Cardinal). Antioxidant activities were consistent with phenolic content trends, with significant tyrosinase enzyme suppression and high SPF factor observed. Principal Component Analysis highlighted strong correlations between phenolic profiles and antioxidant activities. This study is the first to examine how grape ripeness affects phenolic content and biological activities in Algerian grape seeds. It identifies optimal harvest times for maximizing bioactive compounds and supports the use of grape seed extract in sunscreens and antioxidants. |
