POTENSI TABIR SURYA EKSTRAK ETANOL DAUN MATOA (POMETIA PINNATA) DENGAN VARIASI KONSENTRASI PELARUT

Abstract

Secondary metabolite compounds that have potential as sunscreens are flavonoids with chromophore groups. Flavonoid compounds are found in the matoa plant (Pometia pinnata). This study aimed to determine the possibility of matoa extract sunscreen with various solvent concentrations. Variations in the concentration of ethanol used were 50%, 70% and 96% ethanol. Matoa leaf simplicia was macerated with each solvent for 3×24 hours. Then the macerate was concentrated using a rotary evaporator. The viscous extract was tested for flavonoid qualitative using the staining method and tested for sunscreen potency using UV-Vis spectrophotometry with absorbance readings at a 290-320 nm wavelength. The potential for sunscreen in the form of an spf value is calculated using the Mansur equation. The results showed that the ethanolic extract of matoa leaves contained flavonoid. Matoa leaf extract has sunscreen potential. The highest SPF value in the extract with 70% ethanol solvent provides ultra protection value.
