Alkaloid and Steroid from the Stem Bark of Jatropha curcas (Euphorbiaceae)

Abstract

The plant Jatropha curcas grows well in different parts of Bangladesh and used in many medicinal
purposes locally. The alkaloid atherospermidine and a steroid stigmasterol were isolated from the ethyl acetate
extract of the stem bark of J. curcas by a combination of column and preparative thin-layer chromatography over
silica gel. The structures of these compounds were determined by spectroscopic analysis (UV, IR, 1H NMR and
13C NMR) and by comparison with published data. This is the first report of isolation of the alkaloid
atherospermidine from this plant.
