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.
