Determination of allantoin in biological, cosmetic, and pharmaceutical samples.
Methods for determining allantoin in biological, cosmetic, and pharmaceutical samples are reviewed. The methods cover 3 main categories: spectrophotometry, alkalimetric titration, and chromatography (thin-layer and liquid). Comments are given on suitability for different sample types and on further development of methods for allantoin determination.
