In-Vitro Efficacy of Crude Extract of Zizipus Jujuba against Selected Bacterial Strains
Abstract- The research was assessed to evaluate the efficacy of crude extract of Zizipus jujuba against selected bacterial strains. The extract of Zizipus jujuba leaves was obtained by three different methods and the inhibition zones obtained through disc diffusion method. A decent antibacterial activity of Zizipus jujuba leaves crude extract of cold water and ethanol was found against Salmonella typhimurium and Staphylococcus aereus. Maximum zone of inhibition through cold water extract was obtained by Enterococcus feacalis (32mm) followed by Staphylococcus aureus (28mm), Salmonella typhimurium (27.52), Klebsilla pneumonia (19mm) and Escherichia coli (19mm). Similarly maximum zone of inhibition through ethanol extract was obtained by Staphylococcus aureus (28mm) followed by Salmonella typhimurium (27.52). The bacterial species showed no sensitivity against hot water extract due to the degradation of alkaloids in hot water. Mean observation taken was that these bacterial species can be inhibited by Zizipus jujuba plant. The study showed that Zizipus jujuba plant can be used to obtained antibiotics having less or no side effect, especially against Salmonella and staphylococcus aureus infections.
