Antimicrobial Properties against Human Pathogens of Medicinal Plants from New Zealand

The emergence of resistant microorganisms towards standard antibiotics has stimulated an on-going exploration for new sources antimicrobials. microbial susceptibility extracts produced from leaf, bark, or rhizome parts nine different New Zealand bushes was investigated using liquid broth dilution and agar plating techniques. Minimum inhibitory (MIC) lethal concentrations (MLC) were expressed in micrograms dry extract per milliliters solution. lowest MIC 62.5 μg/mL determined methanol Kunzea ericoides against Bacillus cereus Candida albicans, ethyl acetate Pseudowintera colorata Staphylococcus aureus. Additionally, K. also presented the MLC 250 S. aureus B. (methanol extract), (ethyl extract). Weinmannia racemosa to (MLC = µg/mL). Some Phormium tenax, Schefflera digitata, Pomaderris kumeraho antimicrobial (MIC 500 Geniostoma ligustrifolium Melicytus ramiflorus plants did not exhibit activity.
