Level of ascorbic acid in Hibiscus sabdariffa samples was determined by titration method using ammonium cerium (IV) sulphate and 2,6- dichlorophenolindophenol. It was found that leaves of Hibiscus sabdariffa have high ascorbic acid content of 28.34mg/100g. Results obtained using ammonium cerium (IV) sulphate were more reliable than 2,6-dichlorophenolindophenol (DCIP) method. 95% level of confidence was found on chemometric comparison of the results obtained from this method.
