摘　　要：采用菌丝生长速率法,测定了6种中草药乙醇提取物对油菜菌核病菌、番茄灰霉病菌、番茄早疫病菌等12种植物病原菌的抑菌活性。结果表明:在粗提物质量浓度为1mg/mL时,红茴香提取物对油菜菌核病菌的抑制率为65.3%;补骨脂乙醇提取物除对番茄灰霉病菌和早疫病菌外,对其他10种病原菌的抑制率均在63%以上,其中对油菜菌核病菌抑制率最大,达到74.9%。在粗提物质量浓度为10mg/mL时,红茴香和补骨脂乙醇提取物对多数供试植物病原菌抑制率在60%以上,特别是对油菜菌核病菌,两种中药乙醇提取物抑制率分别为100%和88.3%;此外,在此浓度下,金钱草乙醇提取物对玉米大斑病菌,蓼子草乙醇提取物对小麦赤霉病菌的抑制率也在60%以上。可见红茴香和补骨脂乙醇提取物对油菜菌核病菌抑制活性最高,具有进一步研究的价值。Antifungal activity of 95％ ethanol extracts from 6 kinds of Chinese herb was tested against 12 species of phytopathogenic fungi using the method of plate growth rate.The results showed that at the concentration of 1mg/mL,the inhibition rate of the extract from Illicium henryi Diels to Sclerotinia sclerotiorum was 65.3％ ; the inhibition rate of the extract from Psoralea corylifolia L.to 10 fungi was greater than 63％ except to Botrytis cinerea and Alternaria solani,and the maximum inhibition rate to S.sclerotiorum was 74.9％.At the concentration of 10 mg/mL,the inhibition rates of the extracts from I.henryiand P.corylifolia to most fungi were more than 60％.Specially,their inhibiton rates to S.sclerotiorum were 100％ and 88.3％,respectively.Besides that,at the concentration of 10 mg/mL,the inhibition rates of the extract from Lysima chiachristinae Hance to Exserohilum turcicum and the extract from Polygonum pubescens Hance to Fusarium graminearum were also more than 60％.The extracts from I.henryi and P.corylifolia showed a best inhibitory activity to S.sclerotiorum,suggesting that further research should be conducted.
