In order to study the inhibitive effects of combination of Benzoic Acid
Cinnamic Acid and Kojic Acid on tyrosinase of mushroom
the effects of combination inhibitor on diphenolase activity were observed by measuring the oxidation rate of L-dopa. Isobolographic plot and interaction index were employed to evaluate the inhibitors synergistic effects. The results show that in 50% inhibitory rate of enzyme activity the interaction index was 0.42 when combined with Benzoic Acid and Kojic Acid at the ratio 7.5∶1
the index was 0.56 when combined with Cinnamic Acid and Kojic Acid at the ratio 3.8∶1
and the interaction index was 0.18 when combined with Benzoic Acid
Cinnamic Acid and Kojic Acid at the ratio 7.5∶3.8∶1. Inhibitive effects of the combinaion of Benzoic Acid
Cinnamic Acid and Kojic Acid mainly produce synergism
the mixture concentration and mixing ratio have a great influence on the synergistic effects.
