Triterpenoids from the Stem Bark of Crataeva nurvala

Abstract

Two triterpenoids, phragmalin triacetate (1) and lupeol (2) were isolated from an ethyl acetate extract
of the stem bark of Crataeva nurvala (Capparidaceae) by repeated chromatography over silica gel. The structures of
these compounds were determined by spectroscopic analyses (UV, IR, 1H NMR, 13C NMR and EIMS). This is the
first report of the systematic phytochemical investigation and the presence of these compounds 1 and 2 from this
plant.
