New aspects for biomass processing with ionic liquids: towards the isolation of pharmaceutically active betulin

Author affiliations

Abstract

By utilising ionic liquids the pharmaceutically active triterpene betulin can be extracted from biomass with significantly improved extraction yield and purity. The recovery of the ionic liquid 1-ethyl-3-methylimidazolium acetate via azeotropic distillation of EtOH/H2O was successfully demonstrated.
