This study aimed to examine changes in the pomological characteristics of fruits, phenolic composition, and antioxidant activity of ‘Boufeggous’ dates (Phoenix dactylifera L.) from various provinces of southeast Morocco, including Errachidia, Zagora, Tata, and Figuig. A significant difference (P < 0.05) was observed between the different ‘Boufeggous’ cultivar samples by analyzing the pomological characteristics, phenolic compounds, and antioxidant activity. Principal Component Analysis (PCA) classified the samples into two distinct groups. The first group comprises samples of ‘Boufeggous’, notably those from Figuig and Zagora, characterized by their large size and remarkably thick flesh. In contrast, dates from Errachidia and Tata had smaller dimensions. The second group consists of ‘Boufeggous’ from Tata, which demonstrates an abundance of polyphenols and displays significantly higher antioxidant activity than dates from other provinces. Therefore, dates originating from Errachidia are richer in flavonoids and anthocyanins. These promising results pave the way for the increased valorization of Boufeggous dates by optimizing agricultural practices and exploring phenolic compounds for nutraceutical applications while adapting these cultivars to the specific conditions of the provinces studied.
