| Résumé : | The chemical composition of the essential oil of Strobilanthus ixiocephala Benth. was determined by GC/MS analysis. The oil obtained from fresh flowering tops of 1st year and 2nd consecutive year was found to possess compositional differences in the percentage of chemical constituents. The GC-mass data of the oil revealed the presence of a new sesquiterpene alcohol ixiocephol (23.4%) and T-cadinol (17.6%). Among the other constituents β-caryophyllene (6.6%) and α-fenchyl acetate (2.2%) were also detected. The second year's oil also contained ixiocephol (3.9%) and T-cadinol (23.1%) along with β-caryophyllene (16%) and α-fenchyl acetate (24.7%) which differed drastically as compared to first year's oil of S. ixiocephala. |
