Vetiver essential oil was obtained from roots of Vetiveria zizanioides by hydrodistillation method. The unique feature of oil is the presence of antipodal terpenoids of which khusinol may be mentioned as representative. Khusinol, a white crystalline solid (m.p. 87 °C) isolated by column chromatography from vetiver oil was subjected to chemical transformations to afford khusinol oxides, cadina-4a,10b-diol and trans-calamenene derivatives. The structures of khusinol and its derivatives were elucidated using spectroscopic techniques.

Khusinol isolated from vetiver oil was subjected to various chemical modifications. Ester derivatives of khusinol were prepared with acetic anhydride and benzoyl chloride. Epoxides of khusinol were synthesized usingperbenzoicacid, vanadium oxyacetylacetonate–t-butyl hydroperoxide, and N-bromosuccinimide– sodium hydroxide. All the compounds showed promising in vitro antifungal potential against Alternaria
