Arbutin is both an ether and a glycoside; a
glycosylated hydroquinone extracted from bearberry plant in the
genus Arctostaphylos. It inhibits tyrosinase and thus
prevents the formation of melanin. Arbutin is therefore used as a
skin-lightening agent. Arbutin is found in wheat, and is
concentrated in pear skins. It is also found in Bergenia
crassifolia.
