水茄氯仿萃取物微乳剂配方的筛选

为有效利用水茄资源,开发绿色环保并具有优良抑菌活性的水溶性农药应用于生产,通过对溶剂、乳化剂、水质及其量的筛选,确定水茄氯仿萃取物微乳剂初始配方;对pH、微乳液稳定性、低温稳定性、热贮稳定性、透明区域以及有效成分稳定性进行测定,确定其合格性。结果表明:二甲基亚砜对水茄提取物溶解效果最好,5g氯仿萃取物中加入20mL二甲基亚砜即可完全溶解并保持稳定;By-110为最佳乳化剂单体,每5g氯仿萃取物加入10g保证优良乳化性能;5%有效成分含量为水茄提取物微乳剂最佳有效成分含量;蒸馏水为最佳水质。该条件下制备的微乳剂剂型理化性状稳定,是一种合格的剂型。

Screening of Chloroform Extracts from Solanum torvum Micro-emulsion

In order to make full utilization of S.torvum resources,develop green environmental-friendly water-soluble pesticides with good antibacterial activity to use in production,After screening of solvens,emulsifiers,the type of waters,and the amount of every factors,the initiative microemulsifier formulation was determined.Through a series of performance testing,pH,the microemulsion stability,low temperature stability,thermal stability,transparent area,stability of active components,formulation was proved to be eligible.Results:Dimethyl sulfoxide was of the best dissolution effect,5 g chloroform extract was added with 20 mL solvent,By-110 monomer was the best emulsifier,Every 5 g chloroform extract was added to 10 g to ensure excellent emulsification,the best effective component content was 50;and the distilled water was the best choice.Through the performance test,the physical and chemical properties of this formulation were very stable.By various tests,Solanum torvum 5％ micro-emulsion is a qualified formulation.
