Antimicrobial Effects and Resistant Regulation of Magnolol and Honokiol on Methicillin-Resistant Staphylococcus aureus

Figure 2

Antimicrobial activities of magnolol (a) and honokiol (b) against Staphylococcus aureus (ATCC 6538), methicillin-resistant Staphylococcus aureus (MRSA, ATCC 33591), Bacillus subtilis (ATCC 6633), and Escherichia coli (ATCC 8739). All strains were cultured at 34°C for 24 h with tryptic soy medium (Difco) under aerobic conditions before the assay. For antibacterial activity test, Mueller-Hinton medium (Difco, Detroit, MI) was used.
