A New Erythrinan Alkaloid Glycoside from the Seeds of Erythrina crista-galli

Abstract

A new Erythrina alkaloid glycoside, named erythraline-11β-O-glucopyranoside, was isolated from the seeds of Erythrina crista-galli L., together with five known Erythrina alkaloids and an indole alkaloid. The structure of the new alkaloid glycoside was elucidated by spectroscopic methods, and all of the compounds were evaluated for their antiviral activity against tobacco mosaic virus.
