Antibacterial constituents of <i>Alchornea cordifolia</i> leaves

Abstract

Abstract Alchornea cordifolia (Euphorbiaceae), a traditional African medicinal plant, is widely distributed in West Africa. A number of phenolic acids, notably gallic acid, protocatechuic acid, quercetin, quercetin arabinose and galactose glycosides, together with triisopentenyl guanidine were isolated from a methanolic extract of the leaves. The first two, and last one of these compounds showed considerable antibacterial activity.
