Abstract

Plant and plant material are essential for animal and human health care and also important for microbial management program. Pakistan has a great wealth of C. sinensis which has valuable use as tea not only in Pakistan but all over the world. The present study was carried out in vitro to determine antibacterial activity of C. sinensis leaf extracts against Pathogenic bacterial starin by using leaf cold water extract. Antimicrobial activity of C. sinensis was evaluated by well diffusion methods. The zone of inhibition against the tested bacteria was found ranging from 20.00 to 24.31mm. The highest zone of inhibition produced by Cold water extract S. typhi was (24.21 mm), E. coli (20.31 mm) and S. aureus was (22 mm) respectivily. The extracts of C. sinensis leaf were found to be valuable antibacterial agent. This study furnish the way for further consideration and investigate to find out the active compounds accountable for the plant biological activity with the necessary minimum inhibitory concentration (MIC). Further studies should carry out to find out the accurate mechanism of action by which extracts exert their antimicrobial effect to recognize which can be used in drug development for safe health care services
