The objective of the study is to investigate the phytochemical constituents and antimicrobial activity of alcoholic (ALTP) and aqueous (AQTP) extracts of stem barks of Thespesia populnea (Malvaceae) by Cup plate technique. Preliminary phytochemical investigation was carried out to identify various phytochemical constituents present in these extracts. It was found that the ALTP contained alkaloids, carbohydrates, glycosides, saponins, proteins, steroids, flavonoids, tannins and phenolic compounds; AQTP contains alkaloids, carbohydrates, glycosides, saponins, proteins, flavonoids, tannins and phenolic compounds. The aqueous extract of Thespesia populnea (Linn) bark showed significant anti-microbial activity against the tested bacterial organisms compare to ethanolic extract. However the zone of inhibition exhibited by the test extracts was found to be less than that of the reference standard drug (Ciprofloxacin).
