ABSTRACT
Erythrina variegata L. (Fabaceae) is a thorny deciduous tree with thick
clusters of scarlet or showy red flowers. In Bangladesh the plant is
found throughout the country and is used as an important medicinal
plant. A wide range of chemical compounds have been isolated from
this plant, such as alkaloids, flavonoids, triterpenoids saponins, lectin
etc. Two steroid compounds namely stigmast-4-en-3-one and
stigmasta-4,22-dien-3-one were isolated as mixture from this plant by
vacuum liquid chromatography (VLC) and column chromatography
and the structures were elucidated based on nuclear magnetic
resonance (1HNMR) spectroscopic analysis.
