八角茴香抑菌活性的初步研究

采用生长速率法,测定了八角茴香不同器官的提取液对玉米小斑病菌(Helminthosporium maydis)、小麦纹枯病菌(Rizoctonia cerealis)、番茄褐斑病菌(Helminthosporium carposaprum)、棉花黄萎病菌(Verticillium dahliae)的抑菌作用,结果表明,当质量浓度为0.1 g/mL时,八角茴香不同器官的提取液对4种病原菌菌丝生长都有一定的抑制作用,但不同器官的抑菌活性不同,其中八角茴香根和枝提取液的抑菌活性较低,抑菌率均低于50%,果皮和叶提取液的抑菌活性较高,抑菌率均高于50%。

Preliminary Studies on Antifungal Activity of Illicium verum

The fungistasis of Illicium verum were tested with isolate hypha of Helminthosporium maydis,Rizoctonia cerealis,Helminthosporium carposaprum and Verticillium dahliae under di-fferent cultivating conditions.The concentration of these extracts was 0.1g/mL.Results showed that Illicium verum had plenty of bioactive substance to restrain hypha growth.Different tissue of Illicium verum had different antifungal activity.The root and branch extracts of Illicium verum had weak fungistasis,and the antifungal rates of extracts of Illicium verum to 4 tested fungi were lower 50%.However,seedcase and leave extracts of Illicium verum had strong fungistasis,and the antifungal rates of extracts of Illicium verum to 4 tested fungi were higher 50%.
