Abstract
The cytotoxic potential of the different solvent extracts of Equisetum debile were examined by using brine shrimp lethality bioassay. However, n-hexane, ethyl acetate and n-butanol extract exhibited quite potent activity in brine shrimp lethality bioassay with LC50 4.25, 3.36 and 4.40 μg/mL, respectively. These result suggested that they might be contain antitumar or pesticidal activity. Further, ethyl acetate extract showed significant free radical scavenging activity with IC50 24.8 μg/mL. On the other hand, ethyl acetate and n-butanol extract demonstrated excellent antibacterial activity with a zone of inhibition of 9 ± 1mm against the tested pathogenic microorganisms.
