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&plusmn;519 mg kg&oline;<SUP>1</SUP>) 
  was greater than spinach and lower than chard. The nitrite ion concentrations 
  were much more in the leaves of kale (111&plusmn;4 mg kg&oline;<SUP>1</SUP>) than in 
  stalks on the contrary of chard. Oxalate content was lower in kale (2970&plusmn;672 
  mg kg&oline;<SUP>1</SUP>) than in spinach and chard.
