摘  要：
以黄瓜炭疽病菌(Colletotrichum lagenarium)和白菜黑斑病菌(Alternaria brassicae)为供试真菌,采用生长速率法对126种中草药的80%乙醇提取物进行了离体生物活性测定。结果表明:在提取物供试质量浓度为0.01 g/mL条件下(初筛),龙葵、猫爪草、枇杷叶等27种中草药提取物对至少一种病原真菌的菌丝生长抑制率超过50%,有6种提取物对2种病原菌抑制率均达50%以上。将初筛抑制率达50%以上的提取物浓度稀释为0.005 g/mL,进一步对相应病菌进行测试,发现有11种中草药提取物对黄瓜炭疽病菌的抑制率达60%以上,有3种提取物对白菜黑斑病菌的抑制率在40%以上。

摘  要：
The antifungal activities of 126 species of medical plant extracts(MPE) were tested against mycelia growth of Colletotrichum lagenarium and Alternaria brassicae.The result showed that at the concentration 0.01 g/mL,the antifungal rate of 27 MPE(for example,Soianum nigrum,Ranunculus ternatus and Eriobotrya iaponica)was more than 50% against at least one tested fungi.The antifungal rate of 6 MPE was more than 50% to both of the tested fungi.At the secondary screening, the tested MPE were diluted to 0.005 g/mL.The inhibitory rate of 11 species to C.lagenarium was more than 60%,the inhibitory rate of 3 species to A.brassicae was up to 40%.
