Abstract:

Filter paper diffusion method and plate coating method were separately used to determine inhibitory effect and minimum inhibitory concentration (MIC) of volatile oil from peppers against bacteria, molds and yeasts. Results indicated that volatile oil from Zanthoxylum bungeanumm Maxim or Zanthoxylum bungeanumm Mei could inhibit the growth of gram-negative bacteria, gram-positive bacteria, mould and fungi. The maximum inhibitory effect on Penicillium sp. and Aspergillus niger was observed. Therefore, volatile oil from peppers will be promising in the filed of medicine as a natural antimicrobial agent.

Key words: Zanthoxylum bungeanumm Maxim, bioactive component, volatile oil, bacteriostatic action
