The amyrins are three closely related natural chemical compounds of the triterpene class. They are designated α-amyrin, β-amyrin and δ-amyrin. Each is a pentacyclic triterpenol with the chemical formula C30H50O. They are widely distributed in nature and have been isolated from a variety of plant sources such as epicuticular wax. All three amyrins occur in the surface wax of tomato fruit.[3] α-Amyrin is found in dandelion coffee.[citation needed]
