Application
Rhododendrol: An Inhibitor of Tyrosinase.
Rhododendrol (chemical name) is a phenol compound found in extracts of White Birch (Betula pubescens) and Nikko Maple (Acer nikoense). Rhododendrol suppresses melanin biosynthesis and the mechanism is shown to be due to its competitive inhibition of tyrosinase activity. However, rhododendrol have also been found to cause white blotches on skin. Although its mechanism of action remains unknown exactly, there is a report that the white blotches may be caused by metabolites of rhododendrol.
