Structure Elucidation of Betulinic Acid from Sesbania grandiflora Root

Abstract

Betulinic acid, a known triterpene compound that has been successfully isolated from the ethyl acetate extract of the root of Sesbania grandiflora. The structure elucidation of betulinic acid was performed using one-and two-dimensional nuclear magnetic resonance, ultraviolet and infrared spectroscopy, and fast atomic bombardment mass spectrometry as well as by comparing with the literature data. This compound was found for the first time from the Fabaceae family, in particular Sesbania grandiflora.
