Rubus chingii is a well reputed member of Chinese traditional medicine system and is used for managing different ailments since historic times. The present report elucidates the growth impeding effect of R. chingii flower extract against multidrug resistant Escherichia coli, Klebsiella pneumoniae and Staphylococcus aureus. The extracts were prepared using standard Soxhlet extraction method using ethanol, methanol and acetone as a solvent. The extracts were further subjected to agar streak method and the stains that showed their sensitivity were further evaluated for minimum inhibitor concentration (MIC) assessment through TCC method. Subsequently the MIC was further used for well diffusion assay. All the strains used in the study showed their sensitivity towards R. chingii flowers extract in respective solvents. Highest antibacterial activity was seen against E. coli. and S. aureus whereas the lowest activity was recorded against K. pneumoniae. Thus the study reported herewith provided an insight into the antibacterial efficacy of R. chingii flower extract against MDR E. coli., S. aureus and K. pneumoniae.
