摘　　要：介绍一种以水为介质的新型植物源农药1.5%银杏酸微乳剂。根据微乳剂形成的机理,通过溶剂、助溶剂、乳化剂等系统的筛选制备出了1.5%银杏酸微乳剂,经过试验确立了较佳的配方。1.5%银杏酸微乳剂的组成如下:银杏酸1.5%,十二烷基苯磺酸钙/壬基酚聚氧乙烯醚(体积比1∶1)15%～20%,乙醇和正丁醇15%～20%,去氯离子水40%～60%。研究确定了1.5%银杏酸微乳剂主要技术指标:pH值为6～8,透明温度范围0～60℃。This paper describes a new type of botanical pesticide formulation, a Ginkgolic acids 1.5% microemulsion utilizing an aqueous medium. Research was conducted on microemulsion principle, emulsifier and solvent screeing. The quality index for ginkgolic acids 1.5% ME are as follows： 1.5% ginkgolic acids, 15 to 20% DBS-Ca/NP-10（1：1, by vol）, 15 to 20% ethyl alcohol and butanol, and 40 to 60% deionized water. Technical indexes were determined for the ginkgolic acids microemulsion as follows： a pH value is from 6 to 8 and a transparency range is from 0 to 60 ℃.
