Vetiver Oil and Its Sedative Effect

摘要

The essential oil obtained by steam distillation from the roots of Vetiveria zizanwides (L.) Nash was investigated for their chemical constituents by GC and GC/MS. The major volatile components belong to the sesquiterpene group such as khusimol, α-vetivone, andβ-vetivone. The sedative effect of vetiver oil upon inhalation in rats was studied by observing the number of crossing and rearing motilities. The results showed that vetiver oil decreased rearing motility when compared to the control group.
