Studies on Cow’s Urine. Part 1. On an Enol Compound and Brown Oil obtained from Cow’s Urine

Abstract

1. A crystal was extracted from cow’s urine, which formula was to be C10H10O2 having an enol group in it from an experiment with active carbon used as the adsorbent. This substance was obtained from the urine excreted by cows fed on green grass from spring to autumn, but not from the urine excreted by cows fed on ensilage during winter. 2. A kind of oil was also extracted from cow’s urine at the same time. This oil was apparently the cause of the peculiar odour of cow’s urine, and p-cresol and phenol are identified as chief components. 3. By the acetylation, and methylation of the substance mono-acetyl and mono-methyl derivatives were obtained. It was found that one oxygen atom of two in the the substance took part in forming an enol group. 4. A spectrum curve of the substance was obatined by Beckmann’s spectrophotometer. © 1953, Japan Society for Bioscience, Biotechnology, and Agrochemistry. All rights reserved.
