Anti‐microbial activities of root extracts of Cichorium intybus L .
Inhibitory activities of root extracts of Cichorium intybus L.extracted by petroleum ether,ethyl acetate and ethanol to seven pathogenic fungi and three pathogenic bacteria were determined in v itro.The preventative and controlling effects of root extracts of Cichorium intybus L.on wheat powdery mildew were tested with wheat growing in pots.Extracts by ethanol and ethyl acetate were able to inhibit the fungi and bacteria to some extent, and the extract by ethyl acetate to a stronger extentat 10g.L‐1.The extract by ethyl acetate significantly inhibited mycelium growths of wheat fusarium head blight, corn northern leaf blight and Tobacco brown spot at an inhibition rate of more than 80％, and spore germinations of wheat root rot, corn northern leaf blight, and tobacco brown spot at an inhibition rate of more than 80％.The diameters of their inhibition zones to Bacillus subtilis and Staphylococcus aureus reached 20.01mm and 17.23 mm, respectively ; their preventative and controlling effects on wheat reached 50.93％ and 65.82％, respectively.
