Purification of betulinic acid from Eugenia florida (Myrtaceae) by high-speed counter-current chromatography.

Abstract

A high yield of betulinic acid (up to 17% from the ethanolic extract) was found in the leaves of Eugenia florida collected in south-eastern Brazil, making this species a potential commercial source of the title compound. Extracts of E. florida were subjected to solvent partition, and rapid high-speed counter-current chromatography (HSCCC) was applied to the… (More)
