Medicinal plants represent an essential source of drugs and have played an important role in healthcaresystem.PyracanthacrenulataandZanthoxylum armatumhave been used as traditional medicine. The main aim of the study was to find the antibacterial activity of the selected plants against bacterialspecies:E.coliandPseudomonasaeruginosa. The solvents used for plant extraction were hexane, chloroform, ethanol and aqueous. The in vitro antimicrobial activity was performed by Agar disk diffusion method. The hexane and aqueous extracts showed moderate activity whereas theethanolicextractsshowedasignificantantibacterial activity. In the study Tetracycline was used as standard. The combined ethanolic extract of both the selected plant showed the synergistic effect on the bacterial strain tested. This leads to the conclusion that the combined effect can have possible application in the development of products as antimicrobial.Keywords: Pyracantha crenulata, Zanthoxylum armatum, Antibiotics, MIC, Antimicrobial activity |
