【摘要】 环糊精具有特殊的疏水空腔结构,能与多种客体分子形成包合物。农药制成环糊精包合物后,其溶解性、刺激性、化学稳定性、释药速度及其生物利用度等方面有明显的改善。因此,环糊精在农药制剂方面有着重要的应用价值。综述了环糊精-农药包合作用机理、包合物的形成条件及稳定因素,具体介绍了环糊精及其衍生物对农药的稳定效应、增溶性能、光降解催化作用,以及它们在手性农药分离和农药残留检测上的应用,并对其发展趋势和前景做了展望。更多还原

【Abstract】 Cyclodextrins, containing peculiar hydrophobic cavum, could form inclusion complexes with various guest molecules. The solubility, pungency, chemical stability, release rate and the biological utilization of pesticide would be improved markedly by making cyclodextrin inclusion compounds, so cyclodextrins have important value in pesticide formulation. In this paper, the inclusion mechanism of cyclodextrin-pesticides, formation conditions and stability factors of inclusion complexes were reviewed, along with a detailed discussion of cyclodextrin and its derivatives influence on pesticides, such as stabilization, solubilization, photocatalytic degradation, applications in chiral pesti- cides separating and pesticide residues determinating, development trends and prospects for future were also discussed.更多还原
