<![CDATA[Exposure to UV rays can cause several skin problems, such as redness, sunburn, erythema, and ageing. The dangerous effects of UV radiation require more protection of the skin, such as sunscreen. Jengkol leaves (Pithecellobium lobatum Benth.) are a plant that contains phenolic compounds that can absorb UV radiation, so they can act as sunscreens. This study aimed to determine the activity of sunscreen using in vitro methods in the ethanol extract of P. lobatum leaves based on the sun protection factor (SPF),% transmission of erythema (% Te), % transmission of pigmentation (% Tp) and its total phenolic content by UV-vis spectrophotometry. The best sunscreen activity of the ethanolic extract of P. lobatum leaves was at a concentration of 400 ppm with an SPF value of 28.29 ± 0.034 (ultra), % Te and % Tp were included in the sunblock category. The total phenolic content of the ethanolic extract of the leaves of P. lobatum was 394.45 ± 6.40 mg of gallic acid equivalent per gram extract (mg GAE/g extract). The ethanolic extract of the Pithecellobium lobatum leaves has great potential as a sunscreen product.]]>
