Abstract

It has been well known since ancient times that medicinal plants have antimicrobial activity due to the presence of bioactive constituents; therefore they become important sources of drugs formulation. The antibacterial activity of seed extracts of Black pepper was evaluated by well diffusion method. Acetone, methanol and benzene solvents were used for the extraction. During the analysis Pseudomonas aeruginosa and Staphylococcus aureus both were found most sensitive to the benzene extract and inhibition zone measured as 16mm for both bacteria at 100?g/ml. Minimum activity was shown by both acetone and methanol extracts. The study concluded that antimicrobial activity of extracts increases as the concentration increases.
