In Vitro and Molecular Docking Studies of Antiglycation Potential of Phenolic Compounds in Date Palm (<i>Phoenix dactylifera</i> L.) Fruit: Exploring Local Varieties in the Food Industry

The Moroccan date-growing sector is rich in a wide diversity of varieties but faces major challenges, notably the undervaluation of certain varieties intended mainly for animal feed. In this study, our objective was to evaluate the antiglycation activity of four date varieties, including three low-market-value varieties and one high-market-value variety, harvested during two seasons (2021 and 2022). In addition, to improve our knowledge of the antiglycation potential, molecular docking analyses were carried out. The results of the antiglycation activity of the date extracts showed strong activity, particularly for the ‘Khalt Khal’ variety, which showed a 50% inhibition concentration (IC50) of 1.83 mg/mL and 2 mg/mL in 2021 and 2022, respectively. In addition, the molecular docking analysis also showed the possible link between the bioactive compounds identified and their mechanisms of action. Our findings suggest new evidence for the antiglycation properties of the bioactive compounds present in dates. These results suggest the use of these varieties as a source of bioactive molecules or as a food additive. This could make it possible to create medicines or food products with a high commercial value using dates, which could help to treat the complications associated with glycation
