Zone of inhibition (ZOI) values are reported as mean ± SD of three replicates. Asterisks (*) and hash (#) represent extract contents in discs 5 mg/disc and 3.33 mg/disc, respectively. The extract contents present in other discs were 10 mg/disc. PE: petroleum ether, BZ: benzene, CH: chloroform, EA: ethyl acetate, AC: acetone, ET: ethyl alcohol, AQ: water, Imi: imipenem (10 µg/disc), Mero: meropenem (10 µg/disc), and Ptz: piperacillin tazobactam (100/10 µg/disc).
