Abstract– Meyna spinosa represents a traditionally used plant whose methanol extract’s qualitative phytoconstituent analysis and antibacterial activity have been investigated in the present research using established procedures. The results of the investigation demonstrate that Meyna spinosa methanol extract contains phytoconstituents, including tannins, alkaloids, terpenoids, saponins, flavonoids, and phenolic compounds, but not carbohydrates, fixed oils, or lipids. Antibacterial activity was examined against X. campestris. In this investigation, it is observed that the stem of Meyna spinosa had the lowest Minimum Bactericidal Concentration (MBC) at 7.22μg/ml, followed by a methanolic extract of Meyna spinosa (Leaves) at 9.87μg/ml. This value is four times the minimum inhibitory concentration (MIC) against the related microorganisms and significantly lower than the MIC of the leaf extract. The stem extract of M. spinosa exhibited significant antibacterial activity against the test pathogens in the disc diffusion testing. The stem extract of Meyna spinosa exhibited significant antibacterial activity against the test pathogens in the disc diffusion testing. The maximum inhibition zone measured 10 mm for the Meyna spinosa (Leaves) methanolic extract (250 μg/ml/disc) and 12 mm for the Meyna spinosa (Stem) methanolic extract (350 μg/ml/disc). The conventional azithromycin discs had a zone of inhibition of 15 mm. Based on the aforementioned findings, it can be inferred that the methanol extract of Meyna spinosa leaves and stems captures rich phytoconstituents that can be used in food technology, pharmaceutical industries, ethnopharmacological fields, etc., to promote health and combat adverse health effects.
