ABSTRACT

This study aimed to determine the sunscreen activity of ethanol extract, subfraction, pure isolate and lotion of Wodyetia bifurcata fruit. In addition, the physical and organoleptic properties of the extract were determined. Sunscreen activity was measured using UV spectrophotometry, and sun protection factor (SPF) values were used. The results show that at the same concentration (extract 12%), the highest SPF value is 39.144±0.450 and the lotion is 37.039±0.368; the lowest SPF value is 36.815±0.067, and the lotion is 25.798 ± 0.392 (subfraction B). The SPF values of the pure isolate and lotion are 9.104±0.268 and 6.091±0.187, respectively. The physical properties of the extract lotion comply with the 1996 Indonesian national standards, and the most preferred formula is 2%. Gas chromatography-mass spectrometry characterization results showed that the main compound in the ethanol extract was oleic acid (18.39%). In comparison, the pure isolate obtained was β-sitosterol (4.56%), which was confirmed by proton nuclear magnetic resonance (NMR) and carbon-13 NMR data. Extract, subfraction, and pure isolate of W. bifurcata fruit have potential as sunscreen agents based on SPF values.
