Erythrophleum africanum is an endangered West African medicinal plant because of the large-scale use of its stems as toothpicks. Phytochemical screening (preliminary test and thin layer chromatography (TLC) method), a quantitative analysis of total flavonoids, anthocyanidins and radical scavenging activity (2,2'-diphenyl-1-picrylhydrazyl (DPPH) method) of stems of E. africanum were undertaken. The study shows that the quantification of the phenolic compounds (flavonic aglycones and
