AB - The objectives of this research were to determine the quantities
of nitrate, nitrite and oxalate in two vegetables those are popular at Black
Sea coast namely kale and sultana pea. The results were compared with the contents
of spinach and chard. Simultaneous determination of nitrate, nitrite and oxalate
was conducted with capillary electrophoresis by using an acidic run buffer to
reverse the electroosmotic flow. Full factorial design with three variables
was applied to decide the optimum capillary electrophoretic experimental conditions.
The limit of detection was improved by large volume sample stacking. The average
amount of nitrate in fresh kale leaves (2016±519 mg kg‾1)
was greater than spinach and lower than chard. The nitrite ion concentrations
were much more in the leaves of kale (111±4 mg kg‾1) than in
stalks on the contrary of chard. Oxalate content was lower in kale (2970±672
mg kg‾1) than in spinach and chard.
