The amyrins are a pair of closely related natural chemical compounds of the triterpene class. They are designated α-amyrin and β-amyrin. Each has the chemical formula C30H50O. They are widely distributed in nature and have been isolated from a variety of plant sources. α-Amyrin is found in dandelion coffee.
