    • It is desirable to provide a gas chromatography type of chemical analysis method for estimating the change of body smell with progressive ageing of a living subject over a period of years by 1) utilization of the smell distinguishing ability of an experimental animal, 2) instrumental analysis, or 3) a combination of them. The present inventors found that the amounts of several volatile organic substances (e.g., 2-phenylacetamide, indole and phenol) present in mouse urine as substances responsible for the body smell are increased or decreased with ageing. The change in body smell with ageing of an animal can be estimated by quantitatively analyzing these compounds by an instrumental analysis method such as Y-shaped labyrinth method (involving live animals in a maze), gas chromatograph (GC) or high performance liquid chromatography (HPLC).
    • 期望提供一种气相色谱法的化学分析方法,用于通过1)利用实验动物的气味鉴别能力来估算活体受试者在多年的渐进老化中的身体气味的变化,2)仪器分析 ,或3)它们的组合。本发明人发现,作为负责身体气味的物质,存在于小鼠尿液中的几种挥发性有机物质(例如2-苯基乙酰胺,吲哚和苯酚)的量随着老化而增加或减少。 通过使用Y型迷宫法(包括迷宫中的活体动物),气相色谱仪(GC)或高效液相色谱法(GC)等仪器分析方法对这些化合物进行定量分析,可以估计动物老化的身体气味的变化, HPLC)。
