Six phenolic substances in bovine urine associated with oak leaf poisoning were identified by means of the ferric chloride reaction, paper chromatography and gas-liquid chromatography. The results indicate that these are neither oak tannin nor tannic acid but small molecular weight phenolic compounds. The concentration of free volatile phenols in the urine of cattle affected by oak leaves (n = 9, 26.57 +/- 11.20 mg litre-1) was significantly higher than in normal cattle (n = 9, 2.59 +/- 0.03 mg litre-1).
通过氯化铁反应、纸色谱法和气-液色谱法，鉴定出牛尿中与栎树叶中毒相关的六种酚类物质。结果表明，这些物质既不是栎木单宁，也不是单宁酸，而是小分子质量的酚类化合物。受栎树叶影响的牛尿液中游离挥发性酚的浓度（n = 9，26.57±11.20毫克/升）显著高于正常牛（n = 9，2.59±0.03毫克/升）。
