| alpha-Amyrin Usage And Synthesis |
Uses | a-Amyrin is a natural chemical compound of the triterpene class. It is a pentacyclic triterpenol widely distributed in nature and has been isolated from a variety of plant sources such as epicuticular wax. | Definition | ChEBI: A pentacyclic triterpenoid that is ursane which contains a double bond between positions 12 and 13 and in which the hydrogen at the 3beta position is substituted by a hydroxy group. | Purification Methods | Purify it by acetylation to the acetate followed by hydrolysis and recrystallisation from aqueous MeOH or from EtOH. The acetate when crystallised from pet ether, n-heptane or CHC |
