Study of the Major Flavonoids from Balanites aegyptiaca, Cissus petiolata and Hegeina abyssinica

Abstract

In this study, phenolic compounds were extracted from roots of Balanites aegyptiaca, seeds of Hagenia abyssinica and roots of Cisuss petiolata using 95% ethanol. The crude ethanolic extracts of the studied species were subjected to paper chromatography. In this way compound I was isolated from the roots of Balanites aegyptiaca. The structure of this isolate was elucidated by a combination of spectral techniques (UV, IR, NMR and MS) and the following tentative structure was proposed: The seeds of Hagenia abyssinica gave compounds II and III. The following tentative structures were proposed for these isolates: IV Compound IV was isolated from roots of Cisuss petiolata and The following tentative structure was suggested:
