Antibacterial activity was measured at three different concentrations (20, 80 and 120 μM/disc) as described in methods section. Inhibition zones (mm) are reported as average of three replicates. Antibiotics were used as positive control. Abbreviations: Cin cinnamaldehyde, Eug eugenol, std. standard, a meropenem (10 μg/disc), b vancomycin (30 μg/disc)
