The concentration of the extracts was 780 μg·mL−1

IC50 Minimum inhibitory concentration to inhibit at least 50% or the radical (n ≥ 3).

1Values are mean ± standard deviation of at least three repetitions. Means followed by different lowercase letter in a same column are different at a significance level of 0.05.
