|
Antimicrobial activities of ethanol extracts of about 60 endemic Korean herbs and medicinal plants were investigated. When compared to the group treated with phenoxyethanol as a positive control, the growth of Pseudomonas aeruginosa was inhibited by Styrax japonica, Stevia rebaudiana, Morus Leaf, Coptis chinensis and Slavia miltorrhiza Bunge, the latter showing the strongest inhibition (97%). The growth of Staphylococcus aureus was inhibited by Acorus calamus, Pinus densiflora, Ginkgo biloba, Dryopteris crassirhizoma, Chrysanthemum zawadskii, Slavia miltorrhiza Bunge and Coptis chinensis, the latter showing the strongest inhibition (99%). The growth of yeast type fungi Candida albicans was inhibited to about 35% by Scutellaria baicalensis Geogr and about 33% by Coptis chinensis as determined by paper disk method. The growth of bacterium Malassezia furfur was inhibited by Paeonia lactiflora, Rosa multiflora, Coptis chinensis, Citrus aurantium L. subsp, Paeonia suffruticosa Andrews, and Galla rhois, the latter showing the strongest inhibition (57%). The growth of Propionibacterium acnes was inhibited by Galla rhois, Paeonia lactiflora, Morus bombycis, Cucumis sativus, Stevia rebaudiana, Coptis chinensis and Slavia miltorrhiza Bunge. Interestingly, Coptis chinensis and Slavia miltorrhiza Bunge showed the strongest inhibition (99%) similar to that in postive control. The possible components and their action modes were suggested and discussed.
