Comparative Investigation of the Sesquiterpenoids Present in the Leaf Oil ofCymbopogon distans(Steud.) Wats. var. Loharhket and the Root Oil ofCymbopogon jwarancusa(Jones) Schult.

The leaf oil of Cymbopogon distans (Steud.) Wats, chemotype Loharhket and the root oil of Cymbopogon jwarancusa (Jones) Schult. were examined by GC and GC/MS and found to qualitatively exhibit a very similar sesquiterpenoid composition. The sesquiterpenoid content of the C. Distans and C. Jwarancusa oils was 79.6% and 38.0%, respectively. Most of the sesquiterpenoids were isolated by liquid chromatography and their structures assigned on the...
