▎精油簡介

岩蘭草源自於坦米爾語Vetiverr,以斧頭收割之意,葉片跟芒草有點類似,通常會由眾多葉片集結成一大株,岩蘭草莖葉直立,其下有分支眾多、柔軟彈韌的根莖,根部抓地力強,具有來自土壤的堅實穩固的力量,可作為水土保持的植物,被認為是“世界上具有長根系的草本植物”,深密的根部埋於地下可達3至4米長。

也正因此,岩蘭草精油的採集和提取過程非常複雜和耗時耗力。採集工人需要徒手挖掘在地下綿延的根系,並完整清洗它們,之後還要切成較短的長度後將它們在陰涼處乾燥1-2天,以使萃取出的精油更具濃郁香氣。

▎成分解析

|主要成分:倍半萜醇

岩蘭草成分非常多元,主要成分為岩蘭草醇(vetiselinenol,50-75%),其他還有倍半萜烯(beta-vetivenene、delta-selinene),倍半萜酯,倍半萜酮(alpha-vetivone,beta-vetivone、khusimone),酸等。其香氣來源主要受到α-、ß-岩蘭草酮和客烯酮影響,氣味被描述為一種甜的、木香和煙熏的香味。

|成分1:岩蘭草醇(vetiselinenol)

▸ 有四種不同異構物,混合出現在岩蘭草精油中,統稱岩蘭草醇,屬倍半萜醇。

|成分2:β-岩蘭草烯(beta-vetivenene,又稱香根草烯)

▸ β-岩蘭草烯化學結構。

|成分3:α、β-岩蘭草酮(α、β- vetivone)

▸ 屬倍半萜酮,相較於倍半萜酮,具柔軟性、相對穩定。

|研究認證
