| Plant | LC50 (mg/mL) | Selectivity index (SI) | |||||
|---|---|---|---|---|---|---|---|

S. typhi: Salmonella typhi; S. flex: Shigella flexneri; K. pneu: K. pneumoniae; B. cer: Bacillus cereus; E. coli: Escherichia coli; P. mirab: Proteus mirabilis. Doxorubicin hydrochloride in μg/mL was used as positive control. Minimum inhibitory concentration values of extracts (mg/mL) from previous works; LC50 = Lowest concentration of extract which is lethal to 50% of the cells.
