Azaleatin is a chemical compound. It is an O-methylated flavonol, a type of flavonoid. It was first isolated from the flowers of Rhododendron mucronatum in 1956[1] and has since been recorded in 44 other Rhododendron species, in Plumbago capensis, in Ceratostigma willmottiana[2] and in Carya pecan.[3] It has also been found in the leaves of Eucryphia.[4]

Glycosides

Azalein is the 3-O-α-L-rhamnoside of azaleatin.
