The concentration of non-enzymatic antioxidants such as ascorbate and glutathione in tissues is one of the major plant responses to biotic and many abiotic stresses, including metals. Therefore, it is crucial to develop the most effective methods for simultaneous quantitative analysis of these antioxidants. Capillary zone electrophoresis allows relatively fast and effective analysis. The aim of the paper was to apply and optimise the capillary electrophoresis conditions for simultaneous determination of glutathione, glutathione disulphide, ascorbate, and dehydroascorbate in small plant tissue samples exposed to copper and cadmium. The method ensures good linearity and reproducibility, with correlation coefficients 0.988 for ascorbate and 0.999 for glutathione and glutathione disulphide, and with detection limits approximately 2.50, 0.65 and 0.50 ppm, respectively. Cu stress was found to increase the ascorbate concentration and glutathione content in leaves, while Cd increased glutathione in the oldest leaf segments and root.

Zawartość nieenzymatycznych antyoksydantów takich jak kwas askorbinowy oraz glutation w roślinach jest jedną z głównych form odpowiedzi roślin na biotyczne i abiotyczne czynniki stresowe, w tym na metale ciężkie. Dlatego też niezbędne jest rozwijanie efektywnych metod jednoczesnego ilościowego oznaczania tych antyoksydantów. Elektroforeza kapilarna pozwala na takie relatywnie szybkie i efektywne analizy. Celem pracy było zastosowanie oraz optymalizacja metody jednoczesnego pomiaru zawartości glutationu, disiarczku glutationu, kwasu askorbinowego oraz kwasu dehydroaskorbinowego w małych próbkach roślinnych z użyciem elektroforezy kapilarnej. Opracowana metoda zapewnia dobrą liniowość i powtarzalność ze współczynnikami korelacji na poziomie 0,988 dla kwasu askorbinowego oraz 0,999 dla glutationu i disiarczku glutationu, z limitem detekcji odpowiednio 2,50; 0,65 oraz 0,50 ppm. Stwierdzono, że stres indukowany nadmiarem Cu powodował wzrost zawartości kwasu askorbinowego i glutationu w liściach, podczas gdy po zastosowaniu Cd obserwowano wzrost zawartości glutationu w starszej części liścia i korzeniu.
