摘　　要：采用生长速率法,以棉花枯萎病菌(Fusariumoxysporum)等菌种为供试菌种,对苍耳各提取液进行抑菌活性测定。结果表明,当质量浓度为0.1g/ml时,苍耳的各个器官均有抑菌作用,具有开发研究价值。其中苍耳全株和苍耳叶的乙醚、丙酮提取液具有较好的抑菌效果。苍耳全株的乙醚、丙酮提取液对3种病菌的抑菌率分别为79.2%,100%,100%;76.8%,100%,100%。苍耳叶乙醚、丙酮提取液对4种病菌的抑菌率分别为83.6%,100%,100%,75.3%;88.4%,100%,100%,86.9%。The fungistasis of Xanthium sibiricum were tested with isolate hypha of Fusarium oxysporum, Valsa mali, etc. under separate cultivating conditions. The concentration of these extracts was 0.1g/ml. Results showed that Xanthium sibiricum had plenty of bioactive substance to restrain hypha growth. Diethyl ether and acetone extracts of Xanthium sibiricum (the whole, not including fruit) and these two kinds of extracts of leaf had strong fungistasis. The antifungal rates of diethyl ether and acetone extracts of Xanthium sibiricum to 3 tested fungus were 79.2%,100%,100%;76.8%,100%,100%。The antifungal rates of diethyl ether and acetone extracts of leaf to 4 tested fungus were 83.6%,100%,100%,75.3%;88.4%,100%,100%,86.9%。
