ANTIBACTERIAL ACTIVITY OF METHANOLIC RHIZOME EXTRACT OF ALPINIA CALCARATA ROSC. (ZINGIBERACEAE)
- Alpinia calcarata, antibacterial, Salmonella paratyphi
The methanolic rhizome extract of A. calcarata was evaluated for its antibacterial activities against five bacterial strains Pseudomonas aeuroginosa, Proteus vulgaris, Salmonella paratyphi, Bacillus thurungiensis and Staphylococcus faccealis. The extract has inhibited all the tested bacterial species with different manner at various concentration. However the higher level zone of inhibition in 400 (mg/ml) is significant against all the above said bacterial strains of these Salmonella paratyphi. Based on the present study it can be conculuded that the plant rhizome possess potent anti bacterial activity.
