青草飼料を与えた乳牛の尿より活性炭を吸着剤に用いてC<sub>10</sub>H<sub>10</sub>O<sub>2</sub>の化学組成を有する化合物を結晶状に単離した.酸素1原子はエノール姓水酸基の形で存在している事を認め,又同時に活性炭に吸着されて来るものの中より特有な牛尿臭を有する褐色油を得た.この油を減圧蒸溜した物の中より<i>p</i>-cresol及びphenolをaryloxy醋酸の形で分離確認した.<br> 終に元素分析は薬理研究所大畑氏に,吸収スペクトルの測定は北海道水産物検査所の小泉氏にお願いした事を附記し,御指導を賜つた北大小幡教授,東大石館教授と共に深甚なる謝意を表する.

1. A crystal was extracted from cow's urine, which formula was to be C<sub>10</sub>H<sub>10</sub>O<sub>2</sub> having an enol group in it from an experiment with active carbon used as the adsorbent. This substa-nce 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.<br> 2. A kind of oil was also extracted ffom cow's urine at the same time. This oil was apparently the cause of the peculiar odour of cow's urine, and <i>p</i>-cresol and phenol are identified as chief components.<br> 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.<br> 4. A spectrum curve of the substance wds obatined by Beckmann's spectrophotometer.
