Abstract

Ultraviolet (UV) rays as a sun light can gaves risk of causing; pigmentation effect, premature aging, although skin cancer. This research was conducted by utilizing 70% ethanol extract and purified mahogany seed extract (Swietenia Mahagoni Jacq.). The research was conducted to determine the total phenolic content by reacting the sample solution with the folin-ciocalteu reagent and measuring the absorbance value at a maximum wavelength of 749 nm. The measurement of SPF value is carried out according to the Mansur equation whose absorbance is measured at a wavelength of 290-320 nm. In this study phytochemical screening was conducted to determine the compounds contained in the extracts and purified extracts of mahogany seeds. The results obtained from calculating TPC (Total Phenolic Content) in ethanol extract were 1.849 mg GEA/gram, and 2.517 mg GEA/gram in purified extract. SPF value obtained with a concentration of 200ppm in ethanol extract was 0.66 ± 0.008918, while the SPF value of purified extract was 1.18 ± 0.009386. Phytochemical screening results and purified mahogany seed extracts showed that positively contained alkaloid compounds, polyphenols / tannins, flavonoids, terpenoids, and saponins.
