Essential oil froma new chemotype of C.aromatica Salisb. collected from the high altitude region ofNorthern Indiawas analysed byGCFID and GCMS on polar and non polar columns. On polar column, thirty-five constituents were identified in the essential oil of rhizomes representing 92.94% identification and thirty-nine constituents were identified in the essential oil of its leaves representing 97.99% identifications. The major constituents in the rhizome oil were identified as camphor (27.50%), 1,8 cineole (12.39%) and curdione (10.66%) and 1, 8 cineole (34.01%), camphor (13.94%), -terpineol (6.31%) and -terpinolene (5.04%) in the leaf oil.Analysis on nonpolar column resulted in identification of thirty-one constituents in the rhizome oil representing 86.70% identifications and twenty-nine constituents identified in the leaf oil representing 94.44%identification. The major constituents were camphor (17.86%), 1, 8 cineole (14.95%), isoborneol (10.70%) and borneol (6.64%) in the rhizome oil and -pinene (6.06%), camphene (7.49%), 1,8 cineole (21.87%), camphor (11.75%), and isoborneol (6.44%) in the leaf oil.
