Arbutin

Arbutin (β-Arbutin) is a competitive inhibitor of tyrosinase, with Kiapp values of 1.42 mM for monophenolase; 0.9 mM for diphenolase. Arbutin is also used as depigmenting agents[1]. Arbutin is a natural polyphenol isolated from the bearberry plant Arctostaphylos uvaursi, possesses with anti-oxidant, anti-inflammatory and anti-tumor properties[2][3].
