Α-AMYRIN Usage And Synthesis

Uses

α-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 oleanane which has a double bond between positions 13 and 18, and in which the hydrogen at the 3beta position is replaced by a hydroxy group.

Purification Methods

Purify it through an Al2O3 column and eluting with pet ether (40-60o) then Et2O and recrystallising from pet ether or EtOH. The acetate crystallises from Ac2O or pet ether and has m 242-143o and [] D +82.8o (c 0.81, CHCl3) [Crow & Michael Aust J Chem 8 133 1955, Barton et al.
