Biological studies of indigenous medicinal plants--I: physicochemical and antimicrobial screening of non-alkaloidal constituents of some solanaceous seeds.
The seeds of Atropa belladonna Datura fastuosa D. stramoniurn and Hyoscyamus niger were investigated for the isolation and anti-microbial activity of non-alkaloidal constituents. The compounds were separated by column chromatography and spectral studies i.e. IR and UV were performed to ascertain their chemical nature. The anti-microbial activity of crude extracts and purified compounds was tested against Gram positive and Gram negative bacteria and a fungus. All the micro-organisms tested were markedly inhibited, however, the crude extracts as well as the purified compounds isolated from the seeds of A. belladonna and D. fastuosa showed little inhibitory activity.
