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。
通過超聲波提取法和液液分配萃取法製備連錢草萃取物,採用生長速率法測定連錢草萃取物對4種植物病原真菌的抑菌活性。結果錶明:連錢草的石油醚萃取物和氯倣萃取物對蘋果腐爛病菌、棉花立枯病菌、黃瓜枯萎病菌、番茄灰黴病菌等4種植物病原真菌均有較彊的抑製活性,其中氯倣萃取物對棉花立枯病菌的抑製作用最彊,EC50為0.619 3mg/mL。石油醚萃取物對4種植物病原真菌的EC50分彆為:0.837 3、3.517 8、1.496 0、2.3517mg/mL,氯倣萃取物對4種植物病原真菌的EC50分彆為:0.619 3、4.458 6、1.689 8、1.556 3mg/mL。
