چکیده
In the present study the leaves of Swertia chirayita were subjected to phytochemical analysis and the impact of the leaf extract of Swertia chirayita was tested against Staphylococcus aureus, Bacillus subtilis and Salmonella typhi. The phytochemical analysis revealed the presence of various phytochemicals such as alkaloids, flavonoids, phenols, quinones, saponins, tannins and terpenoids. The antibacterial activity was done by Agar disc diffusion method and the result showed that the leaf extract of Swertia chirayita showed 100% inhibition of all the test bacteria. The Minimum Inhibitory Concentration (MIC) of Swertia chirayita leaf extract that showed 100% inhibition was 0.13 mg, 0.36 mg and 0.13 mg in case of Staphylococcus aureus, Bacillus subtilis and Salmonella typhi respectively.
