Two medicinal plants, Scoparia dulcis (Scrophulariaceae) and Nymphaea lotus (Nympaeaceae) were studied to verify their medicinal claims by the Nupes in Nigeria. The crude aqueous and ethanolic extracts of the medicinal plants were tested against Stapylococcus aureus, Microsporum canis, Candida albicans, Salmonella typhi, Streptococcus species, Escherichia coli and Proteus vulgaris. Ethanolic extracts of Scoparia dulcis and Nymphaea lotus produced greater zones of inhibitions on Staphylococcus aureus and Streptococcus species while aqueous extracts produced zones of inhibition on Staphylococcus aureus from both plants. The ethanolic extracts of Scoparia dulcis produced zones of inhibition on Microsporum canis and Candida albicans while ethanolic extract of Nymphaea lotus produced zones of inhibition on Candida albicans. Escherichia coli, Samonella typhi and Proteus vulgaris were the most resistant. Bioactive agents like Saponins, glycoside and carbohydrate were detected in Scoparia dulcis, while saponins, tannins and alkaloids were found in Nymphaea lotus.
