The present study was to investigate the phytochemical analysis and antibacterial activity of <em>A. lineata </em>plant extracts. The methanolic extracts of <em>A. lineata </em>showed a variety of phytochemicals such as alkaloids, flavonoids, phenols, tannins, terpenoids etc. The quantitative estimation of major phytochemical constituents revealed maximum amount of phenolic content in the roots and alkaloids in both the stem and leaf. Correspondingly, the highest amount of tannins and terpenoids were recorded in the leaf and flavonoids in the root samples. Furthermore, the plant extracts of <em>A. lineata </em>showed antibacterial activity against both Gram-positive and Gram-negative bacterial strains. Comparatively, stem extract was effective against <em>Streptococcus mutans </em>(18.19±0.04 mm), leaf extract against <em>Enterobacter faecalis </em>(24.13±0.14 mm) and root extract against <em>Bacillus subtilis </em>(24.09±0.14 mm) at 30 μg/μL concentration. However, the leaf extract was more effective against <em>Escherichia coli </em>(25.13±0.16 mm), <em>Pseudomonas aeruginosa </em>(20.20±0.13 mm) and <em>Klebsiella pneumoniae </em>(18.18±0.17 mm) at 30 μg/μL concentration. The studies infer that the phytochemical constituents of <em>A. lineata </em>have antibacterial properties and these herbs may be considered as the medicinal plant for treating bacterial diseases.</p> B.
