In Bangladesh it is known as ‘Moyna’. Fruits of M. spinosa are reported to contain sugar, gum and tannic acid whereas the seeds contain esters of palmitic, stearic, oleic and linoleic acids.
Chemical constituents: The present study was undertaken to investigate the antibacterial and cytotoxic activity of the ethanol extract of Meyna spinosa stem. Antibacterial activity was investigated against Staphylococcus aureus. Streptococcus pyogenes, Escherichia coli and Shigella dysenieriae by disc diffusion and broth macrodilution assay. In disk diffusion assay, the extract inhibited all the microorganisms except E. coli. Minimum inhibitory concentration (MIC) of the extract was 1000 Î¼g/ml for S. aureus, S. pyogenes and E. coli, whereas 500 Î¼g/mLfor S. dysenieriae. For cytotoxicity test, the extract was subjected to brine shrimp lethality bioassay. The LD50 of M. spinosa stem extract was found to be 40 Î¼g/mL. Findings of the study justify the use of the plant in traditional medicine and suggests for further investigation.
