The application of capillary zone electrophoresis with UV–VIS and diode array detection for simultaneous analysis of l-ascorbic and d-isoascorbic acids was investigated. The method of analysis was simple, fast and its performance was tested in terms of linearity, sensitivity and detection limit. Twenty-six samples representative of three types of apricot commercial juices (organic, integrated and conventional) were analysed for their ascorbic acid content and data were reported (range n.d.–486 mg/l).
