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

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

应用

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]与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

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] 。
