摘　　要：以荒漠野生有毒资源植物牛心朴子为原料,研究其生物活性物质—生物碱的中试提取工艺;以提取浓缩物为原药,进行了新农药的复配,筛选出1.65%氧苦·牛心朴子生物碱AS。并以此水剂的3种质量浓度为试药,分别在菜青虫和小菜蛾上进行田间防效试验。结果表明,中试提取工艺可行,得到的原药具有杀虫活性,新配制的植物源生物农药对菜青虫和小菜蛾的防治效果很理想。The extraction technology of the alkaloids of Cynanchum komarovii, a wild poisonous plant, and the biological activity of the alkaloids extract were investigated. The biological activities of matrine Cynanchum komarovii alkaloids 1.65% AS was tested with three concentration against Pieris rapae L. and Plutella Xylostella L.. The results showed that the extraction technology is viable and the control effects of the mixing aqueous solution on the two kinds of vegetable insects are ideal.
