3.2. The antibacterial activity
The antibacterial activity of the eight extracts were assayed
in vitro by the agar microdilution method against three resistant
bacteria. The antibacterial activity against each bacterium was
observed to be varied. Table 2 shows that among the eight
plants, K. pandurata exhibited the smallest value of MIC against
MRSA (256 mg/mL) (Figure 1), while S. alata and
C. xanthorrhiza also had the same activity against MRSA
(Figures 2 and 3). This showed that K. pandurata, S. alata and
C. xanthorrhiza had the potential to be developed as antibacterial
agents for MRSA strains.
