Osmorhizole is an allylbenzene essential oil. It’s a derivative of methyl chavicol with the addition of a methoxy group on the benzene ring. It’s also a positional isomer of methyl eugenol and 3,5-dimethoxyallylbenzene.
Natural Sources
Osmorhizole is found in chervil leaves which contain 0.3% essential oil. The essential oil contains pinene, phellandrene, methyl chavicol (21.1-83.10%) and osmorhizole (15.15-57.4%).[2] [3] [4]
In PiHKAL this allylbenzene is incorrectly spelled "osmorrhizole". The reference also makes claims that osmorhizole occurs in carrots. Until it's existence in carrots can be verified by another source this information should be regarded as dubious.
