Zone of inhibition (ZOI) values are reported as mean ± standard deviation of three replicates. Asterisk (∗) represent extract content in discs 5 mg/disc. The extract contents present in other discs were 10 mg/disc. Abbreviations: PE: petroleum ether, BZ: benzene, CH: chloroform, EA: ethyl acetate, AC: acetone, ET: ethyl alcohol, AQ: water, Mero: meropenem (10 µg/disc), and Ptz: piperacillin tazobactum (100/10 µg/disc).
