A preliminary pharmacognostical study was made on ten Nigerian plants. This study consisted of the taxonomic study of the plants; the phytochemical screening and testing for alkaloids, tannins, saponins, and flavonoids; and the use of thin layer chromatography further to separate certain constituents of the plants. The latter was found to give rapid, reproducible separations which could be used to supplement the usual methods for the identification of subsequent collections of a given plant.
