| The soil pH favored by several native plants in Korea ranges 5.33¡7.20, while a more acidic range of pH 3.95¡6.10 is acceptable to exotic plants. Ethanol extracts of native and exotic plants in Korea were investigated for antimicrobial activity against Bacillus sphiaericus 2362, Bacillus thuringiensis var. subtilis and Bacillus thuringiensis var. cereus and Actinomycetes. Higher antimicrobial activity was observed from the extract of exotic plants than those of native plants. The ethanol extract of Ambrosia artemisiifolia var. elatior was observed to have the highest antimicrobial activity against 4 species of soil microbes. Especially, antimicrobial activity of Ambrosia artemisiifolia var. elatior showed the largest clear zone of 48mm in Actinomycetes. Larger clear zone was formed in the order of caffeic acid, benzoic acid and ¥ñ -coumaric acid among the nine chemical compounds. Accordingly, the antimicrobial activity of Ambrosia artemisiifolia var elatior against Actinomycetes was found to be due to the synergetic effect of chemical compounds. |
