Abstract
A triterpenoid dimethyl ester ε-lactone isolated from dammar resin has been shown by X-ray crystallographic examination to be 23-hydroxy-2,3-secours-12-ene-2,3,28-trioic acid (2 → 23)-lactone 3,28-dimethyl ester (IV): it is probably formed biogenetically by oxidation of asiatic acid (II).Keywords
