Xb. Chen et al., DETERMINATION OF ALLANTOIN IN BIOLOGICAL, COSMETIC, AND PHARMACEUTICAL SAMPLES, Journal of AOAC International, 79(3), 1996, pp. 628-635
Methods for determining allantoin in biological, cosmetic, and pharmac
eutical samples are reviewed, The methods cover 3 main categories: spe

and liquid). Comments are given on suitability for different sample t
ypes and on further development of methods for allantoin determination
.
