我们对pH区带精制CCC的持续研究扩展了这一领域, 它的应用包括:(1)分离碱性化合物 以三乙胺为固定基,(2)开发了一种 可以应用于配体亲和性的置换操作模式 分离,以及(3)使用手性分离剂分离手性化合物。 选择器在固定阶段。 该方法的实用性已被 证明了对各种分析物的分离和纯化, 作为从朱顶红和小朱顶红提取物中提取的生物碱,结构 从反应混合物中分离异构体, 氨基酸和寡肽以及D,L- 亮氨酸衍生物。
英文摘要
Our continuous research on pH-zone-refining CCC has extended the domain of its applications which include: (1) separation of basic compounds using triethylamine as a retainer base, (2) the development of a displacement operation mode which may be applied to a ligand-affinity separation, and (3) the separation of chiral compounds using a chiral selector in the stationary phase. Utility of the method has been demonstrated on the separation and purification of various analytes such as alkaloids from extracts of Amaryllis and Vinca Minor, structural isomers from a reaction mixture, the acidic and basic derivatives of amino acids and oligopeptides and a pair of optical isomers of D,L- leucine derivatives.
