  1. Conc- concentration of the extract; Cipr-ciprofloxacin; Amp -ampicillin; DMSO–Dimethyl sulphoxide, mm-millimeter, μg-microgram, μl-microlitre; ml-mililitre; SEM-standard error of the mean; ‘0’ - no zone of inhibition;(−) - no significant difference between extract and standard drugs. P-values <0.05 indicates significant difference between the extract and the standard drugs or positive controls. Values greater than 6 mm diameter of the well indicate some activity
