Abstract
Exposure to excessive UV rays will form free radicals that can cause damage to the skin. Antioxidant compounds can reduce the adverse effects of free skin. The ethanol extract of arabica green coffee bean (Coffeaarabica L.) contains many antioxidant compounds such as chloronenic acid, ferulic acid, caffeine acid, nkumarat acid, trigenoline caffeine and volatile furan and pyrrole antioxidants. The results showed that ethanol extract of arabica green coffee beans had free radical capture activity against DPPH (1,1-diphenyl-2-picrilhidrazil) which in IC50 was 9.8554 ppm. This research is intended to know the activity of free radical capture to DPPH and physical properties of peel-off antioxidant gel mask of ethanol extract of arabica green coffee bean. The antioxidant activity test was performed by DPPH method. The arabica green coffee bean is extracted by using 70% ethanol solvent with soxhletation method. The ethanol extract of green beans was then formulated into a peel-off gel mask with concentrations of 1, 2 and 3% extracts. The results showed that gel mask gel peel-off ethanol extract of arabica green coffee with extract concentration of 1, 2 and 3% had IC50 value 24.71; 19.07 and 15.55 ppm and belongs to a very powerful antioxidant.
