1 Both EGCG and GCG inhibited tyrosinase in a mixed manner with the IC50 values of 39.4 +- 0.54 muM and 36.8 +- 0.21 muM, and showed a synergism with their combination, while EGCG and GCG combined with kojic acid (IC50 = 19.2 +- 0.26 muM) exhibited antagonism and additive effect, respectively. epigallocatechin gallate tyrosinase Homo sapiens
