Simultaneous determination of L-ascorbic acid, glutathione, and their oxidized forms in ozone-exposed vascular plants by capillary zone electrophoresis


Simultaneous determination of L-ascorbic acid, glutathione, and their oxidized forms in ozone-exposed vascular plants by capillary zone electrophoresis

Simultaneous determination of ascorbic acid (AA), glutathione (GSH), and oxidized glutathione (GSSG) in vascular plants has been achieved by capillary zone electrophoresis. A background electrolyte containing a phosphate buffer of pH 7 and hexadimethrin bromide for dynamic control of electroosmotic flow was used. Separation was performed in less than 5 min. The signal was simultaneously monitored at 265 and 200 nm.
