香茅醇Citronellol)是一种天然有机化合物,存在于多种植物精油以及一些水果中,属于类萜。其两种对映异构体在自然界中均有分布:R-(+)-香茅醇, 存在于香茅油 (50%);而S-(−)-香茅醇存在于蔷薇属植物精油中(18–55%),以及天竺葵属植物等。[1]

制备

[编辑]

每年生产数百万公斤的香茅醇。 香茅醇主要由香叶醇橙花醇亚铬酸铜催化剂上加氢化合成[2]均相催化剂用于生产对映异构[3][4]

应用

[编辑]

香茅醇用于香水和驱虫剂,[5]农业害螨引诱剂。[6]香茅醇在短距离内是一种很好的驱蚊剂,但保护性能随距离增加大大降低。[7]环糊精结合能增强驱蚊效用,有效时间提升至1.5小时。[8]

香茅醇是生产玫瑰醚的原料。[9]

健康和安全性

[编辑]

美国食品药品监督管理局(FDA)将香茅醇归入“公认安全”(GRAS)的分类,[6]在食物中仅限作为香料用途添加。[10]有报道称一些人群可能对香茅醇敏感,但其作为食品添加剂时的剂量是否足以使人过敏则尚不清楚。[11][12]

就皮肤安全性而言,香茅醇已被评估为一种驱虫剂[13]
