Antibacterial activities of Fr2 of green tea seed saponins against Escherichia coli, Salmonella typhimurium, Salmonella enteritidis, Salmonella gallinarum, Salmonella choleraesuis, Salmonella pullorum, Salmonella dublin, and Staphylococcus aureus. The antibacterial activities were determined by allowing the bacteria to grow in the presence of various concentrations of saponins using 96-well microtiter plate and then checking the viability of bacteria by measuring OD660 with spectrophotometer. Data are expressed as means of experiments in triplicate ± SEM. Data are statistically significant at P < 0.05.
