Tyrosinase inhibitor activity using tyrosinase from mushroom as enzym and L-tyrosine as a substrate with kojic acid as a standard. The IC50 value of antioxidant activity of belimbing wuluh fruits extract is 2331.69±339.09 mg/ml and 320.76±79.54 mg/ml from leaves extract. The IC50 value of antioxidant activity greater than rutin 5.92 mg/ml. Tyrosinase inhibitor activity can be seen from IC50 values is 186.85±9.37 mg/ml from fruits extract and 150.57±6.25 mg/ml from leaves extract. The IC50 value of tyrosinase inhibitor greater than kojic acid 16.68 mg/ml. Our findings showed that belimbing wuluh leaves extract better than fruits extract.
