Solanum surattense which belongs to the family Solanaceae is one of the medicinal plants in India. Biological activities such as antidysentric, antiseptic, antidiuretic is reported by the whole plant. This study reveals both the qualitative and quantitative screening of phytochemicals along with antioxidant and antibacterial activity of different extracts of leaf, root and stem of S. surattense. Ethanolic, methanolic, petroleum ether and aqueous extracts were used for the screening purpose. Alkaloids, terpenoids, flavonoids, phenols, saponins, cardiac glycosides, resins and anthroquinones were found to be present in the extracts in reasonable qualities. In the quantitative screening aqueous leaf extract showed highest amount of total phenolics (28.10 ± 0.19 mg/gm), the same extract showed high amounts of total flavonoids (16.20 ± 0.89 mg/gm) and aqueous stem extract showed highest percentage of antioxidant activity (56.70 ± 0.10 µg/ml). Antibacterial activity was analyzed by using disc diffusion method against gram positive and negative bacteria. All the extracts revealed activity against all the strains. Aqueous leaf extract showed highest zone of inhibition against Staphylococcus aureus. Ethanolic extract of leaf showed minimum inhibitory concentration (MIC) values of 15.0 µg/ml against Bacillus subtilis and Staphylococcus aureus. Even ethanolic stem extract also showed lowest MIC value of 15.0 µg/ml against Bacillus subtilis.
