Background: Bridelia scandens Wild. (Euphorbiaceae) leaves are widely used to cure asthma, bronchitis pleurisy, exudation, sores in mouth and genital cancers. Objective: To evaluate antibacterial activity of the leaf calli methanol extract (LCME). Materials and Methods: Mass production of leaf calli was established on MS medium supplemented with 0.5 mg/L BAP and 0.5 mg/L 2, 4-D. Methanol extract of the dried calli was subjected to HR-LCMS analysis, antibacterial screening of the extract was carried out against human pathogenic clinical isolates. Molecular docking study of HR-LCMS identified compounds was performed by docking with bacterial enzyme DNA gyrase. Results: HR-LCMS analysis of LCME shows that the compounds azaperone bifonazole, fusidic acid, lasalocid and quinine as the major constituents. The antibacterial screening of LCME against clinical pathogens showed significant bactericidal activity against the strains Staphylococcus aureus (17.67\±0.88 mm.d.), Streptococcus pneumonia (13.67\±0.33), Pseudomonas aeruginosa (16.33\±0.67), Salmonella typhi (17.67\±0.33), and Vibrio cholera (15.33\±0.33) as compared to the standard drug ciprofloxacin. The molecular docking of lasalocid against the bacterial enzyme DNA gyrase exhibited good binding affinity of -4.9 kcal/mol, good drug likeness (2.5589), 2 hydrogen bonds and hydrophobic interaction with 7 amino acid residues, so that lasalocid processes good inhibitor as compared to other 4 compounds. Conclusion: LCME of Bridelia scandens showed significant antibacterial activity against Staphylococcus aureus and Salmonella typhi. Lasalocid is the major phytocomponent of LCME which exhibited good inhibitory activity against bacterial enzyme DNA gyrase. This investigation supported traditional claim of LCME as potential antibacterial drug.\

Natural products are emerging out as potent and alternative therapies for many diseases. Today herbs have become the part of mankind, because of its manifold ways in targeting diseased cells with minimal effects on normal cells and tissues. The present research investigated the in vitro antioxidant activity and hepatoprotective of B.scandens leaf. Preliminary phytochemical analysis exhibited the presence of most of the constituent in ethanol extract (BSE). Antioxidant capacity of various extracts of B.scandens was examined. DPPH assay revealed that ethanol extract has a good antioxidant with IC50 value of 31.68\μg/ml, whereas standard ascorbic acid with 8.78 \μg/ml. BSE revealed dose dependent response with increase in concentration for reducing power assay. ORAC assay directly measured the scavenging capacity and BSE (2485 trolox eq/gm) was found to be potent than other extracts. In vitro hepatoprotective activity was performed for BSE using MTT assay in BRL 3A cell line, which revealed nontoxic dose with CTC50 value more than 1000 \μg/ml. At the dose 200 \μg/ml, BSE and standard silymarin offered cell protection of 57\% and 76 \% respectively. Present study concludes that B.scandens leaf extract possess antioxidant potential and protect the liver cells against CCl4 damage. However in vivo studies are being carried out to validate the traditional usage of Bridelia scandens.
