Abstract

Certain parts of 36 kinds of plant were extracted by 75% ethanol and water. The extracts were tested their microbial inhibition activities against several food spoilage microorganisms, Bacillus subtilis, Lactobacillus plantarum, Leuconostoc mesenteroides, Pseudomonas fluorescens, Bacillus cereus and Saccharomyces cerevisiae. The ethanol extract of amur cork was shown inhibitory effect on all 6 species of the microorganisms tested. Chinese pepper, sesame cake, gromwell and oak were on 5 species except S. cerevisiae or P. fluorescens and bamboo leaves, lycopi herba, paulownia and rigida were on 4 species. In general amur cork exhibited the strongest inhibition with a few exceptions on certain species. By disc diffusion method, the ethanol extract of leaf mustard showed the highest inhibition effect on B. subtilis, amur cork on L.plantarum, L. mesenteroides and B. cereus, and amur cork and gallnut on P. fluorescens. Mostly the ethanol extracts in comparison with water extracts showed higher inhibition in most of plants but a few exhibited higher in water extracts.
