RT Journal Article SR Electronic T1 A CONTRIBUTION TO THE STUDY OF THE METABOLISM OF SALICYLIC ACID JF Journal of Pharmacology and Experimental Therapeutics JO J Pharmacol Exp Ther FD American Society for Pharmacology and Experimental Therapeutics SP 297 OP 314 VO 26 IS 4 A1 HOLMES, E. G. YR 1925 UL http://jpet.aspetjournals.org/content/26/4/297.abstract AB 1. After the ingestion of salicylates by a normal individual on a mixed diet, salicyluric acid was isolated from the urine, and identified. The identification rested on solubility, amino and total nitrogen content, which were satisfactory, and melting point, which was identical with a pure specimen of synthetic salicyluric acid. 2. For doses of sodium salicylate of from 2 to 5 grams, the salicylic/salicyluric ratio is constant at the value of .40/60. 3. This ratio, after the ingestion of 1.5 grams of synthetic salicyluric acid, reaches the value of 8/92. 4. The distillation method for the estimation of total salicyl in urine, described by Hanzlik, is not satisfactory when solutions of pure salicyluric acid in urine are employed. 5. No evidence has been found for the destruction of salicylic acid in the body. 6. Under the conditions of these experiments, no salicyl-glycuronic compound was excreted.
