Plant biochemistry and biosynthesis

Betulinic, ursolic and oleanolic acids isolated from the aerial parts of Eriope blanchetii (Lamiaceae) were subjected to different esterification reactions, yielding 12 C-3 position ester derivatives. All compounds were identified using spectroscopic techniques, such as IR, 1H-NMR and MS. The derivatives were further investigated for their antioxidant level, Artemia salina lethality and antimicrobial activity.
