Antibacterial Activity of Putranjiva Roxburghii Wall: A Medicinal Plant

Medicinal plants can be defined as plants that possess therapeutic properties or exert a beneficial pharmacological effect on the human or animal body. P. roxburghii is a good moderate sized evergreen medicinal tree with pendent branches and the leaves are simple and alternately arranged. The aim of this study was to screen and determine significant antibacterial activity of dry seeds of P. roxburghii. The ethanol extract of P. roxburghii seed showed highest zone of inhibition in all the bacterial strains tested Staphylococcus aureus (G+) (16mm).  Streptococcus mutans (G+) (19mm) Bacilus subtilis (G+) (20mm). E.coli (G-) (21mm). Klebsiella pneumonia (G-) (14mm) Proteus vulgaris (G-) (16mm). The  acetone  extract of  P. roxburghii seeds showed a minimum zone  of  inhibition against the bacterial pathogens. They are Staphylococcus aureus (G+) (11mm).  Streptococcus mutans (G+) (8mm) Bacilus subtilis (G+) (14mm). E.coli (G-) (15mm). Klebsiella pneumonia (G-) (13mm) Proteus vulgaris (G-) (15mm). The  aqueous  extract of  P. roxburghii seeds showed the lowest zone  of  inhibition against the bacterial strains. They are  Staphylococcus aureus (G+) (13mm).  Streptococcus mutans (G+) (9mm) . E.coli (G-) (14mm)
