Abstract

Methanolic leaf extracts of Ricinuscommunis collected from different climatic zones of Pakistan were screened for antimicrobial activity against different Gram-positive and Gram-negative human important pathogenic bacteria as Escherichia coli, Staphylococcus aureus, Salmonella typhi, Klebsiellapnemoniae, Shegella, Vibreo cholera and Proteus, by using agar cup diffusion method. It was found that all Ricinuscommunis species from different origin shows high zone of inhibition against the tested pathogens. These results demonstrated that R. comminus contain potential components that may be beneficial for evolution of pharmaceutical and can be use as a medicine against different types of bacterial phathogenic flora of human body.
