Wikipedia

Arbutin

Arbutin is a glycoside; a glycosylated hydroquinone extracted from the bearberry plant in the genus Arctostaphylos among many other medicinal plants, primarily in the family Ericaceae. Applied topically, it inhibits tyrosinase and thus prevents the formation of melanin. Arbutin is therefore used as a skin-lightening agent. Very tiny amounts of arbutin are found in wheat, pear skins, and some other foods. It is also found in Viburnum opulus and Bergenia crassifolia. Arbutin was also produced by an in vitro culture of Schisandra chinensis.

It can be prepared synthetically from the reaction of acetobromoglucose and hydroquinone in the presence of alkali.
