Table 4.
Minimum bactericidal concentration (MBC) of potential extracts derived from T. cordifolia stem.
| Extract fractions | Bacteria | |||
|---|---|---|---|---|
| K. pneumoniae | Proteus spp. | E. coli | Pseudomonas spp. | |
| PE | nt | 7.1 | nt | nt |
| BZ | nt | 14.2 | nt | nt |
| CH | nt | nt | nt | 22.73 |
| EA | nt | nt | 4.21 | 1.29 |
| AC | 1.29 | nt | 4.21 | 4.21 |
MBC values are shown in mg/mL. The MBC values of potential extract fractions of T. cordifolia stem samples were determined as described in Section 2. Abbreviations: PE: petroleum ether, BZ: benzene, CH: chloroform, EA: ethyl acetate, AC: acetone and ET: ethyl alcohol fractions, nt: not tested.
