[目的]研究3，5－二羟基甲苯与L－肌肽对酪氨酸酶活性的抑制作用。[方法]从新鲜蜜梨中提取酪氨酸酶，以邻苯二酚为底物，研究3，5－二羟基甲苯、L－肌肽对酪氨酸酶活性的影响。[结果] 3，5－二羟基甲苯与L－肌肽对酪氨酸酶均有一定的抑制作用。[结论] L－肌肽对酪氨酸酶的抑制作用强于3，5－二羟基甲苯。%Objective] To study the inhibition effect of 3,5-dihydroxytoluene (DHT) and L-camosine on tyrosinase activity.[Method] The effects of 3,5-dihydroxytoluene and L-camosine on the activity of tyrosinase extracted from fresh snow pear were analyzed with catechol as sub-strate.[Result] Both 3,5-dihydroxytoluene and L-camosine had certain inhibition effect on tyrosinase activity.[Conclusion] The inhibition effect of L-camosine on tyrosinase activity was stronger than that of 3,5-dihydroxytoluene.
