Antimicrobial activity of ethanol and aqueous extracts of centratherum punctatum cass

Aim: The current study was aimed to investigate the antibacterial efficacy of C.punctatum Cass. Methods: Solvents such as ethanol and water were respectively used to evaluate the antimicrobial potential of the aerial parts of Centratherum punctatum against Staphylococcus aureus, Bacillus subtilis, E.coli and Proteus by well diffusion method. The maximum activity was observed in aqueous extract when compared with that of the ethanol extract. Results: The results of the study revealed that the whole plant extract possess good antimicrobial activity. Water extract of C.punctatum has more antimicrobial potential than ethanol extract. Conclusion: The major chemical constituents of plant may also contribute in the management of various diseases for which it is used as anti cancer, analgesic and wound healing agents.
