Antibiotic resistance in various pathogens has exhibited an imperative need for development of novel therapeutic agents
from natural resources. Since antiquity, plants have been used to treat common infectious diseases. In this regard, the
antibacterial activity of medicinal plant Prosopis cineraria was investigated against Salmonella enterica ser. Typhi (MTCC-733)
and Escherichia coli (MTCC-433). Five different plant extracts (petroleum ether, chloroform, acetone, methanol and water)
were prepared from leaves by using Soxhlet extraction method and examined using Resazurin based Microbroth Dilution
Assay (RMDA) and Disk Diffusion Assay (DDA). According to results of RMDA, acetone extract showed highest activity
against S. enterica and E. coli i.e., 0.195 mg/ml and 0.390 mg/ml respectively. In DDA, acetone extract exhibited significant
zone of inhibition against S. enterica and E. coli at a concentration of 75.0 μg per disc and 125.0 μg per disc respectively.
Whereas, petroleum ether, chloroform, methanol and water extracts showed mild activity. Phytochemical analysis of various
plant extracts revealed the presence of many secondary metabolite including tannins, steroids, flavonoids, alkaloids, glycosides,
terpenoids, etc. The spectrum of activity provides possible source to obtain new and effective herbal medicines to treat infections
caused by S. enterica and E. coli.
