Capillary zone electrophoresis separation of hydrolysates obtained from food industry by-products

Rapid separation of tetracycline derivatives and their main degradation products by capillary zone electrophoresis.

A mixture of five tetracycline (TC) derivatives: minocycline (MC), demeclocycline (DMCTC), doxycycline (DC), and sancycline (SC), as well as each TC derivative from its main degradation product were separated by capillary zone electrophoresis (CZE). The influence of the pH and the concentration and nature of the background electrolyte (BGE) on the separations was investigated. Ethylenediaminete...

Separation and partial characterization of Maillard reaction products by capillary zone electrophoresis.

Capillary zone electrophoresis proved useful for separating small amounts of both charged and uncharged solutes that are otherwise difficult to analyse. A typical complex mixture that had previously resisted all analytical approaches, including reversed-phase separations, is the products arising from the reaction of free amino acids with aldehydic sugars (Maillard reaction products). By using c...

Capillary zone electrophoresis separation of enantiomers of lisuride.

Lisuride is an ergot alkaloid derivative with dopaminergic activity. It is used for treatment of Parkinsonism and some other diseases associated with high level of prolactine. Lisuride is a chiral compound derived from natural ergot alkaloids. A new capillary zone electrophoresis (CZE) method capable of separating the enantiomers of lisuride was developed. Using the optimized conditions (acidic...
