by concentrating each solvent under reduced pressure
(the same as done with the filtrates) and diluting with
10 ml DMSO. Plates were incubated at 37 °C for 18–
24 h. Inhibition zones in mm (including well diameter)
around wells were measured. The antibacterial
activity was expressed as the diameter of inhibition
zones produced by the extracts against test bacteria.
All tests were performed in triplicate.
