Abstract
Cysteine and ergothioneine, being sources of error in the determination of ascorbic acid by means of 2:6-dichlorophenolindophenol, are removed quantitatively by precipitation with mercuric acetate. The ascorbic acid is reversibly oxidized and can be regenerated by H2S.This publication has 5 references indexed in Scilit:
