摘要
以不同溶剂提取瑞香狼毒根的甲醇相、乙醇相、乙酸乙酯相和氯仿相提取物为试材,提取液按照不同浓度稀释,进行室内防蚜试验。结果表明:各类提取物均具有杀蚜活性,但活性的大小差异显著,其顺序依次为,氯仿相>乙酸乙酯相>乙醇相>甲醇相;而且在防效和速效性方面,氯仿相1 000倍液和乙酸乙酯相200倍液与目前最常用的化学药剂相当,均具实质性防效。
Different Isolation of Stellera chamaejasme root extracts against aphids indoor were tested.The results showed that,all types of extracts had killing aphids activity,but activity was significantly different in size,the order of,chloroform> ethyl acetate Phase> Phase ethanol> methanol phase;but also in terms of control efficiency and quick result,chloroform and ethyl acetate 1 000 times、200 times and the most commonly used chemicals,were a substantial controlling effect.
