Determination of Niacin in Cereal Samples by HPLC

摘要

A liquid chromatographic method for the analysis of niacin in cereal products is presented. The sample is extracted in the presence of Ca(OH)2, concentrated and purified on an anion exchange resin, and further cleaned up by oxidation with KMnO4. Final quantitation is by HPLC with ultraviolet detection at 254 nm.
