Phytochemical screening and antimicrobial assessment of Abutilon mauritianum, Bacopa monnifera and Datura stramonium

Three medicinal plants - Abutilon mauritianum, Bacopa monnifera and Datura stramonium were assessed for phytochemical components and antimicrobial activity. The results revealed that all the three plant extracts contained saponins, tannins and alkaloids. Only Datura stramonium contained glycosides. The plants exert varying inhibitory effects on Pseudomonas aeruginosa, Klebsiella pneumonia and Escherichia coli. The minimum inhibitory concentration of the plant extracts ranged between 10% (w/v) (Bacopa monnifera) and 25% (w/v) (A.mauritianum and D. stramonium). Extracts of Abutilon mauritianum, Bacopa monnifera and Datura stramonium could be potential sources of chemotherapeutic agents.
