The phytochemical screening, total phenolic and photoprotective potential of date palm seeds (Phoenix dactylifera l.)

Abstract

Date palm seeds (Phoenix dactylifera L.) are known to contain phenolic compounds that have the potential as natural photoprotective agents. Phenolic compounds extracted by solvent are suitable for the level of polarity. This study aims to determine the compounds, the value of Sun Protecting Factor (SPF), and the difference in the SPF value of ethanol extract of date palm seeds and their fractions (n-hexane fraction, ethyl acetate fraction, and residue fraction). This research is in two stages. It’s the screening stage and the photoprotective test with the spectrophotometric method. This data was analyzed to descriptive qualitative and photoprotective data with graphed prism 8. In this study, the ethanol extract, ethyl acetate fraction, and residue fraction contained phenolic and terpenoid compounds, and the n-hexane fraction contained steroid compounds. Ethanol extract, ethyl fraction, and residue have sunscreen activity, with SPF values ​​of 3.376±0.15; 6, 13±1, 2; and 3.14±0.08. While the n-hexane fraction with an SPF value of 0.512 ± 0.09. The highest SPF value in the ethyl acetate and n-hexane fractions did not meet the photoprotective SPF range. Phenolic compounds as sunscreens. The data analysis showed a significant difference between the ethanol extract, ethyl acetate fraction, residue fraction, and n-hexane fraction of date palm seeds.
