Abstract

A new HPLC test has been developed for monitoring the racemiza‐tion which occurs during the coupling of Z‐Ala‐Trp‐OH with Val‐OMe by various methods. It is based on reversed phase HPLC separation of tripeptide diastereomers (LLL – LDL) and fluorescence rather than UV detection. The extent of racemization has been estimated for different carbodiimides, mixed anhydrides, and additive‐releasing reagents.

## Abstract In this study, a molecularly imprinted functionalized polymer for the selective separation of ractopamine (RAC) was prepared by combining a surface molecular imprinting technique with a sol–gel method process. The polymer was evaluated by static, kinetic adsorption, and selective experi
