Triterpenoids from the Stem Bark of

Abstract

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, 1 H NMR, 13 C 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. Key words: Crataeva, Capparidaceae, Phragmalin triacetate and Lupeol
