| 摘 要： | 以牡丹皮等16种中草药的丙酮提取物为材料，测定了其对5种植物病原菌的生长抑制活性。结果表明：在供试质量浓度为0．05g／mL时，牡丹皮提取物对所有供试病原菌菌丝生长抑制效果最好，除对杨树溃疡病菌菌丝生长抑制率为85.3％外，对其他植物病原菌的抑制率均为100％。高良姜提取物抑菌活性次之。对4种供试植物病原菌菌丝生长抑制率均在80％以上，对番茄灰霉病菌的抑制率最低，也达到68％。黄芩提取物对供试的3种植物病原菌的抑制率超过60％。连翘、知母、蔓荆、乳香和地榆等5种中药提取物分别对供试的5种植物病原菌中的2种有较好的抑菌活性。在供试质量浓度为0．1g／mL时。牡丹皮、高良姜等2种中药提取物对杨树溃疡病菌孢子萌发抑制作用相当明显。抑制率均在80％以上；白花蛇舌草、乳香、川楝等3种中药提取物对杨树溃疡病菌孢子萌发抑制作用次之，抑制率均在60‰以上。

| Abstract: | To screen the active ingredients against plant pathogen, the inhibitory activity of sixteen kinds of Chinese herbs against 5 plant pathogens were examined. The results showed that the extracts of cortex moutan had a good in hibiting rate to all of the five kinds of plant pathogens, and the extracts of Alpinia officinarum also showed good anti-fungal properties with more than 80% inhibiting rate to at least four kinds of plant pathogens at the concentra tion of 0. 05 g/mL. The inhibiting rate of the extracts of cortex moutan and Alpinia officinarurn to the growth of the spore of DothioreUa gregaria was more than 80% at the concentration of 0. 1 g/mL, while that of other three Chinese herbs were more than 60%. |
