SIGMOISIDE E: A NEW ANTIBACTERIAL TRITERPENOID SAPONIN FROM ERYTHRINA SIGMOIDEA (HUA)

SIGMOISIDE E: A NEW ANTIBACTERIAL TRITERPENOID SAPONIN FROM ERYTHRINA SIGMOIDEA (HUA)

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- beta -...

Zusammenfassung: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- beta -D-galactopyranosyl maniladiol (1). Sigmoiside E exhibited antibacterial activity against gram-negative bacteria.
