Abstract
Procedures for S determination involving digestion of plant material with HNO3/HC104 mixtures gave lower values than those using oxygen flask combustion. Tests on a range of S compounds showed that the HNO3/HC104 procedure underestimated S present in methionine, cysteine and glutathione but S in sulfate and the glucosinolate, sinigrin, was not underestimated. Low recoveries using HNO3/HC104 digestion procedures can be due both to incomplete oxidation of certain compounds and to gaseous losses during the vigorous boiling stage of digestion.Keywords
