Unlabelled - This study aimed to evaluate the potential therapeutic effects of leaves and fruits from Algeria. The total phenolic and flavonoid contents, sun protection factor, antimicrobial, antifungal, and antioxidant activities such as DPPH, ABTS, FRAP, CUPRAC, and o-phenanthroline reduction were determined. The findings of the comparative analysis revealed that the leaves contained higher levels of total phenolic content (TPC) and flavonoid content (TFC) compared to the fruit, indicating their maximum antioxidant potential. TPC values for leaves ranged from 528.411 ± 9.94 to 816.352 ± 5.09 µg EAG/mg of dry extract, while for fruits, it ranged from 378.215 ± 5.26 to 579.392 ± 14.2 µg EAG/mg extract/ml. Similarly, TFC values for leaves varied from 65.833 ± 9.42 to 147.986 ± 5.59 µg EAG/mg of dry extract, and for fruits, it ranged from 45.486 ± 5.00 to 90.208 ± 6.77 µg EAG/mg extract/ml. Moreover, both leaves and fruit extracts showed significant growth inhibition against and , with the highest activity against , followed by . The sun protection factor (SPF) values of both leaves and fruits extracts are close to the values of standard sunscreen VICHY. In addition, molecular docking studies identified promising compounds, including Demethyloleuropein, Luteolin-7--glucoside, Apigenin 7-Glucoside, Oleuropein, Pinoresinol, and Syringaresinol monoglucopyranoside of leaves from , these compounds are showing a better binding affinity than native ligands against Rhomboid protease GlpG from , the same thing about luteolin-7--glucoside and apigenin 7-glucoside exhibited similar binding free energy values to the target protein sortase A. The study suggests that leaves and fruits of could be valuable sources for developing drugs against pathogenic oral yeasts, Gram-negative and Gram-positive bacteria.
