Ten medicinal plants’ parts (roots, stembarks, and leaves) were studied to assert their suitabili ty for use in pharmaceutical industries as raw materials. The presence (qualitative analysis), concentration (quantitative analysis) and antimicrobial activities of such phytochemicals as alkaloids, tannins, saponins, steriods, phlobatannins, terpenoids, f lavonoids and cardiac glycosides (CGs) were carried out on the extracts from the plants’ leaves, stembarks and roots. Result indicates an interesting presence of all the phytochemicals in the medicinal plants (i.e. in either of the studied parts), although there are slight variation in the composition of the plant parts. Averagely, tannins shows the highest amount in all the plant studied, followed by alkaloids, while steriods, terpenoids, phlobatannins and cardacglycosides which together constitutes the ge neral phenol shows the least amount. Antimicrobial test reveals the activities of the phytochemicals in the different plant parts, and these has justified the use of the plants in the synthesis of bioactive drugs and hence their medicinal significance for bioprospective and pharmaceutical productions.
