| 摘 要： | 采用菌丝生长速率法测定了19种中草药乙醇提取物对5种果蔬病原真菌的抑制活性.结果表明:在提取物浓度为0.1 mg/mL时,豨莶草对草莓软腐病菌、葛根和鸦胆子对苹果褐腐病菌有抑制作用,抑制率均在20%左右.射干对苹果轮纹病菌和苹果褐腐病菌的抑制率分别为21.47%和21.9%,EC50(有效中浓度)值分别为0.7928、0.9107 mg/mL.马兜铃对番茄灰霉病菌和苹果褐腐病菌的抑制率分别为28.39%和49.64%,EC50值仅为0.3732和0.1256 mg/mL.综合分析认为,马兜铃值得进一步研究开发.

| Abstract: | Ethanol extracts from 19 Chinese herbs were obtained.Then their inhibitory activities against 5 fruit-vegetable pathogenic fungi were assayed in vitro using growth rate method with concentration of 0.1 mg/mL.The results showed that the inhibitory rates of Siegesbeckia pubescens against Rhizopus stolonifer,Pueraria lobata and Brucea javanica against Monilinia fructigena were about 20%.Whereas those of Belamcanda chinensis against Physalospora piricola and Monilinia fructigena were 21.47% and 21.9% respective... |
