The plant sample was collected and dried. The preliminary test for saponnins was carried out and subsequently saponnin was extracted. A compound was isolated using thin-layer chromatography (TLC) and the antibacterial activity was tested. The S. trifasciata-root extracts and the isolated compound demonstrated potent activity against Escherichia coli and Staphylococcus aureus. The zone of inhibition of growth produced ranges between 18.67 and 24 mm at 200 ppm concentration level respectively. It is the best eluent that separated the triterpenoid-saponins was chloroform:methanol:water (20:60:4) with 3 spots having Rf of 0.125, 0.75 and 0.812.
Key words: Sansevieria trifasciata, roots extract, saponins, antibacterial, Escherichia coli, Staphylococcus aureus.
