Abstract
Crude extract prepared from sweet potato possessed inhibitory activity toward mushroom tyrosinase. The inhibitory activity was dependent upon the addition amount of sweet potato extract. After heating the sweet potato extract at $95^{\circ}C$ for 20 min, its inhibitory activity retained 37.3%. Its optimum activity was shown at pH ranges of 5.0-7.0. The tyrosinase inhibitory activity was disappeared by dialysis, which suggests the inhibitory activity of sweet potato extract is caused by some compounds of low molecular weight.
