摘要

在寻找新的天然光保护剂的过程中，巴巴苏(Attalea speciosa)的中果皮因其独特的化学成分和区域意义而成为一个有前途的候选者。本研究考察了巴巴苏中果皮面粉提取物及其组分的体外光保护和抗氧化性能。采用DPPH和ABTS测定抗氧化活性。通过Mansur法测定防晒系数(SPF)，并测定RAW细胞的细胞毒性。样品表现出较高的抗氧化活性，特别是在极性组分中。水乙醇提取物的SPF值为16.69，水提取物的SPF值为14.83。值得注意的是，在测试浓度下，氢乙醇提取物没有表现出细胞毒性作用。我们的研究结果表明巴巴苏中果皮粉是开发光保护剂的潜在来源，可以保护皮肤免受紫外线辐射和对抗自由基。

Photoprotective and antioxidant effect of babassu mesocarp flour extracts

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.
