摘  要:
通过超声波提取法和液液分配萃取法制备连钱草萃取物,采用生长速率法测定连钱草萃取物对4种植物病原真菌的抑菌活性。结果表明:连钱草的石油醚萃取物和氯仿萃取物对苹果腐烂病菌、棉花立枯病菌、黄瓜枯萎病菌、番茄灰霉病菌等4种植物病原真菌均有较强的抑制活性,其中氯仿萃取物对棉花立枯病菌的抑制作用最强,EC50为0.619 3mg/mL。石油醚萃取物对4种植物病原真菌的EC50分别为:0.837 3、3.517 8、1.496 0、2.3517mg/mL,氯仿萃取物对4种植物病原真菌的EC50分别为:0.619 3、4.458 6、1.689 8、1.556 3mg/mL。

摘  要:
Glechoma longituba(Nakai)Kupr was extracted through Ultrasonic extraction and Liquid-liquid distributed extraction.Growth rate method was employed to investigate antifungal activities of the Glechoma longituba(Nakai)Kupr extracts against four phytopathogens.The bioassay results showed that Petroleum ether extract and Chloroform extract had strong antifungal activities to the four phytopathogens,and had the strongest antifungal activities to Thanatepephorus cucumeris Donk.with the EC50 was 0.6193mg/mL.The EC50 of Petroleum ether extract against four phytopathogens were 0.837 3,3.517 8,1.496 0 and 2.351 7mg/mL,respectively,and the EC50 of Chloroform extract against four phytopathogens were 0.619 3,4.458 6,1.689 8 and 1.556 3mg/mL,respectively.
