amyrin
Quick Summary
Amyrin refers to either of two crystalline isomeric triterpenoid alcohols, alpha-amyrin and beta-amyrin, with the chemical formula C30H49OH. These compounds are found in substances like Manila elemi and dandelion roots. Beta-amyrin, in particular, is a pentacyclic triterpene and is abundant in nature, often occurring in plants either freely or as glycosides. The resin elemi, primarily sourced from trees in the Burseraceae family, is a significant source of beta-amyrin. The structure of beta-amyrin is representative of its class and shares a notable relationship with squalene and cholesterol, with squalene serving as a common precursor in biosynthesis for both pentacyclic triterpenes and sterols.12
