Most medicinal plants are traditionally use all over the world to alleviate anaemia. Our study aimed at evaluating the antianaemic chemical composition of the leaf of Lannea kerstingii which is reported to be potent in the management of anaemia by traditional healers. The leaf was extracted using hot water. Phytochemicals, amino acid, vitamins and mineral composition was carried out using standard protocols. Phytochemical screening of the leaf extracts has revealed the existence of saponins, tannins, cardiac glycosides, flavonoids and alkaloids in the extracts. The elemental analysis of leaf extract has shown a good amount of some erythropoietic minerals such as iron, Selenium, zinc, Copper and Cobalt. The vitamins analysis has shown the presence of adequate amount of some haematopoietic compounds, such as folic acid, vitamin C, riboflavin. The amino acid analysis of the leaf has revealed the presence of essentials and non-essential amino acids. The amount of Cystine, tyrosine, methionine, phenylalanine, lysine and leucine are lower in Lannea kerstingii compare to the requirement for adults. The amount of Isoleucine, tryptophan, valine, histidine and threonine are higher in Lannea kerstingii compare to the requirement for adults. These results illustrate that the aqueous extracts of Lannea kerstingii leaf possess antianaemic properties The findings of our study suggest that the leaf of Lannea kerstingii contains haematopoietic properties thus, justifying the use of the plant to alleviate anaemia in Togo.
