Abstract
AbstractA quantitative method is described for the chromatographic separation and subsequent polarographic estimation of adenine in gelatin. The method, which has been applied to about 200 gelatins, has two important features. It is specific for adenine and enables a visual assessment of other purines and pyrimidines to be mode in the course of the procedure.Hide gelatins have adenine contents from 10 200 ppm., but the large majority are from SO 50 ppm., ossein gelatin contains from 4–6 ppm., and pigskin between 30 and 50 ppm.
