Chemical analysis of the stem bark of Erythrina sigmoidea (Leguminoseae) yielded two known isoflavones, 6,8-diprenylgenisteine (3) and warangalone (4) as well as a new triterpenoid saponin designated sigmoiside E (1). Its structure was established by chemical and spectroscopic means as 16-O-β-D-galactopyranosyl maniladiol (1). Sigmoiside E exhibited antibacterial activity against gram-negative bacteria. KEY WORDS: Erythrina sigmoidea, Stem bark, Triterpenoid, Saponin, Isoflavone, Leguminoseae Bull. Chem. Soc. Ethiop. 2007, 21(3), 373-378.
