Medicinal use and chemistry of Erythrina brucei (a medicinal plant of Ethiopian).

Erythrian brucei is a tree grown only in Ethiopia. It grows up to the eight of 15-20 m long with colorful flowers. In different parts of the country the root and stem bark of this plant is used to treat ear infection and other diseases. Previous studies revealed that the flower and seed of E.brucei contain biologically active alkaloids; however, there was no report for the non-alkaloidal constituents of this plant. Recently, however, we did a comprehensive phytochemical investigation on root bark, stem bark and twigs of the plant concentrated on nonalkaloidal compounds. In the study we isolated biologically significant compounds and come up with new compounds which were not isolated so far from the nature and different co-metabolites.
