Abstract
Coffee is a highly consumed and popular beverage consumed in many countries. Its ingredients have a powerful antioxidant capacity and have the potential as sunscreen to protect the skin. This study aimed to examine the antioxidant activity of Arabica, robusta and liberica coffee extracts and the SPF activity of the coffee extract cream formulation. Coffee were macerated with three types of solvents with polarity gradients. The fraction of each coffee was analyzed for antioxidant activity using DPPH and formulated into the cream. Furthermore, the cream was analyzed for its SPF activity. The results of this study indicated that the methanol fraction of Robusta and Arabica coffee has the best antioxidant activity with IC50 values of 8.98 (ppm) and 13.13, respectively. Meanwhile, Liberica coffee has the best antioxidant in the ethyl acetate fraction, IC50 = 10.90 (ppm). In addition, the best SPF values for Robusta, Liberica and Arabica coffees were found in F3 cream with the category of Very Good Protection; 36.087 ± 0.0005; 35.007 ± 0.0005; 36,867 ± 0.0005 respectively.
