    • PURPOSE:To separate and analyze an enantiomeric mixture of chrysanthemumic acid esters with an excellent separating efficiency in a short time, by analyzing a specific enantiomeric mixture of chrysanthemumic acid esters, which is a pyrethroid insecticide, by liquid chromatography using a stationary phase wherein an optically active N-acylated amino acid is grafted. CONSTITUTION:As a packing material having a grafted N-acylated amino acid, e.g., a chromatographic packing material wherein an optically active organosilane represented by formula I is grafted onto an inorganic carrier having a hydroxyl group on its surface, is used as a stationary phase. An enantiomeric mixture of chrysanthemumic acid esters represented by formula II is separated by liquid chromatography. In the formulas, R is a lower alkyl group or a halogen atom; A is an alkyl group including optionally substituted aryl, aralkyl, cycloalkyl or heterocyclic group; R1-R3 are each an alkyl group, an alkoxy group, a hydroxyl group, or a halogen atom; R4 is a lower alkyl or phenyl group; (n) is 2-4; and X is an -NHCO- group or the like.
    • 目的:在短时间内分离和分析菊酯的对映异构体混合物,分离效果极佳,通过使用固定相的液相色谱法分析其中拟菊酯杀虫剂菊酯酯的具体对映异构体混合物,其中光学 活性N-酰化氨基酸被接枝。 构成:作为具有接枝的N-酰化氨基酸的包装材料,例如色谱填充材料,其中将由式I表示的光学活性有机硅烷接枝到其表面具有羟基的无机载体上,用作固定相 。 由式II表示的菊花酸酯的对映体混合物通过液相色谱分离。 式中,R为低级烷基或卤素原子; A是包括任选取代的芳基,芳烷基,环烷基或杂环基团的烷基; R1-R3各自为烷基,烷氧基,羟基或卤素原子; R4是低级烷基或苯基; (n)为2-4; X是-NHCO-基等。
