(1) Control used were: ascorbic acid (500 µM) in antioxidant assay and gentamicin (5 μg) (antibacterial assay). (2) Inhibition zone of H. acetosella leaf extract against Staphylococcus aureus (Gram-positive) and Pseudomonas aeruginosa (Gram-negative). The results are shown as the mean ± standard error of three replicates. Mean with the same letter are not significantly different at the 5% probability level (Duncan’s multiple range test). nd; not detectable.
