Major constituents of North Indian laevorotatory oil, (obtained from wild roots) are antipodal terpenoids, while those of South Indian dextrorotatory
oils (obtained from cultivated roots) are sesquiterpene ketones and alcohols.
The North India Khas oil contains large amounts of khusilal, other sesquiterpenes include khusol, khusimol, khusitone, cadinene and laevojuneol. The South Indian Khas oil constituents are largely nootkatone, vestipiranes and substances of tricyclic zizaane structure. Khusilal is absent in typical dextrorotatory Khas oils.
The oils from other producing countries are found to be dextrorotatory similar to that from South India.
