ABSTRACT
In the search for new natural photoprotective agents, the mesocarp of babassu (Attalea speciosa) stands out as a promising candidate due to its unique chemical composition and regional significance. In this study, we investigated the in vitro photoprotective and antioxidant properties of babassu mesocarp flour extracts and their fractions. Antioxidant activity was evaluated using DPPH and ABTS assays. The sun protection factor (SPF) was determined through the Mansur assay, and cytotoxicity was determined in RAW cells. The samples exhibited high antioxidant activity, especially in the more polar fractions. The hydroethanolic extract had an SPF of 16.69, while the aqueous extract had an SPF of 14.83. Notably, the hydroethanolic extract exhibited no cytotoxic effects at the tested concentrations. Our findings suggest that babassu mesocarp flour is a potential source for developing photoprotective agents to shield skin from UV radiation and combat free radicals.
