ABSTRACT
The antimicrobial activities of the aqueous and ethanolic extracts of roots and stems of Terminalia glaucescens Planch. ex Bth. plant were investigated. The results from this study indicate that the antimicrobial activities of terminalia glaucescens (root and stem) are target microbe specific. Of the tested parts (root and stem), the stem showed a significantly higher antimicrobial activity against Staphylococcus aureus and Streptococcus mutans even at a lower concentration of 3.13 mg/ml. Phytochemical screening of the plant parts reveal the presence of alkaloids, flavonoids, anthraqiunones, saponins, tannins, steroids and terpenoids. In addition cardiac glycosides were found in the stem but absent in the root extracts while phlobotanins and carbohydrates were present in all the extracts except that of ethanolic extract of the root. The potency of the antimicrobial activities of Terminalia glaucescens plant has made both parts suitable for better dental care and cleansing.
