【 摘 要 】

The petroleum spirit (60 - 80°C), chloroform and methanol extracts ofSchwenkia americanaLinn. (Solanaceae) were screened for antimicrobial activity and for their chemical constituents. Phytochemical studies showed that it contained cardiac glycosides, saponins, steroids, triterpenes, flavonoids, cyanogenic glycosides, tannins and alkaloids. Antimicrobial screening showed that at 100 mg/ml, the methanol and chloroform extracts were active againstEscherichia coli, Bacillus subtilis, Staphylococcus aureus, Salmonella typhii, Pseudomonas aeruginosaandCandida albicanswhile the petroleum spirit extract was only active againstE. coli, Bacillus subtilis, S. typhii and C. albicans.Work is going on to isolate and characterize the component(s) responsible for the observed activity.
