MIC values of ethanol extracts and its five fractions from Z. bungeanum leaves against 3 selected bacteria.
| Bacteria | MIC (mg/mL) | ||||||
|---|---|---|---|---|---|---|---|
| ECE | PEF | CF | EAF | AF | MF | Benzylpenicillin | |
| Staphylococcus aureus | 4.93 ± 0.69c | 2.45 ± 1.25b | 4.76 ± 0.17c | 2.38 ± 0.82b | 5.15 ± 0.16c | 2.65 ± 0.97b | 1.31 ± 0.01a |
| Escherichia coli | 4.61 ± 2.11bc | 4.34 ± 1.78bc | 3.15 ± 0.72ab | 2.32 ± 0.83a | 5.70 ± 0.31c | 3.10 ± 0.43ab | >10 |
| Bacillus subtilis | 8.29 ± 0.98c | 4.78 ± 0.42b | 4.48 ± 0.79b | 4.24 ± 0.54b | 5.42 ± 1.04b | 4.10 ± 0.23b | 0.01 ± 0a |
Values are the mean of three replicates ± SD. Means with different letters within a row were significantly different (P < 0.05). Benzylpenicillin was used as the positive control.
