    简介:粪臭素即3-甲基吲哚,为一种具有中等毒性的白色结晶有机化合物,是吲哚的一种衍生物。在自然界中,存在于哺乳动物的粪便(为色胺酸在消化系统中的产物)、甜菜与煤焦油中,具有强烈的粪便气味。在低浓度下,粪臭素具有花香味,并存在于许多花朵与精油中,如橙花、茉莉与Ziziphusmauritiana,因此被用于香水中的香精、定香剂以及食物香料等。其名称来自于希腊文的skato-,意指“动物的粪便”。实验显示,粪臭素会造成山羊、绵羊、大鼠与某些品种小鼠的肺水肿。其似乎会选择性攻击Clara细胞,亦即肺中细胞色素P450酶主要的集中处。这些酶会将粪臭素转换为反应性中间体3-亚甲基假吲哚,此产物与蛋白质形成加合物而伤害细胞。粪臭素通常是白色结晶或细粉状固体,但久置后会转为棕色。可溶解于醇与苯中,在亚铁氰化钾(K4Fe(CN)6·3H2O)与硫酸的溶液中呈紫色。粪臭素具有双环结构,其中一个环是吡咯,并具有芳香性,因为分子结构连续(所有环中的原子为sp2杂化)、平面并遵守4n+2规则(含10个π电子)。可由赫尔曼·埃米尔·费歇尔所发展的费歇尔吲哚合成来制造。其为吸引许多种类雄性兰花蜂的物质之一,这些蜂类搜集此化合物以合成费洛蒙;因此时常被用于吸引并捕捉这种蜂类作研究的诱饵。在一份1994年五家香烟大厂的报告中,粪臭素被列为599种香烟添加物之一,作为香料使用。

    用途:3-甲基吲哚可用作香精及医药中间体,具有令人不愉快的粪臭味,但经大量稀释后有愉快的香味,特别具有灵猫香基的香韵,在干酪、坚果、葡萄等制品中加入少量就有效果,在海味香精中加入,可具鱼肉味。
