R= resistant. Inhibition zone in diameter (mm ± SD) around the discs impregnated with 100 μg per disc of each extract. Penicillin (10 μg / disc) was used as positive control for bacteria.
±: standard deviation of three replicates.
a–d: averages with different letters in the same column are different (P<0.05).
