Volatile constituents of vetiver: a review

“…By analogy with ‘tricyclovetivenol’, bicyclovetivenol refers to a bicyclic constituent of VEO isolated in the early analytical studies of VEO and for which another incorrect perhydroazulenic structure was attributed (Figure ). On the basis of Marshall's work on β‐vetivone, its structure was later revised by Takahashi and described as an eremophillane alcohol for which a ( Z )‐ stereochemistry was arbitrarily attributed to the C 7 –C 11 double bond .…”

“…This tricyclic skeleton is unusual in the plant kingdom and, as described below, a large part of the olfactory specificity of vetiver is due to these constituents. The first account of the presence of a tricyclic sesquiterpenic alcohol in VEO was given by Ruzicka, but its exact structure could not be elucidated at that time. Thirty years later, other authors probably isolated the same compound from Congolese VEO, and proposed the structure of tricyclovetivenol (Figure ), deduced after chemical degradations and IR analyses .…”
