Panicle and bark oils of a variant of Cinnamomum bejolghota (Buch-Ham) Sweet. from North East India

Abstract

Essential oils obtained by hydro-distillation of panicle and bark of Cinnamomum bejolghota (BuchHam) Sweet. Variant II, growing in Upper Brahmaputra valley region in Assam, India were investigated by GC and GC-MS. Twenty seven and 23 components accounting 98.52% and 81.60% in the oils of panicle and bark, respectively, were identified. Linalool (65.00%) was the major component in the panicle oil. The predominent components in the bark oil were a -terpineol (23.30%), linalool (14.40%) and p-cymene (13.90%). The chemical composition of the oils, on comparison with those reported for C. bejolghota, exhibited the natural existence of four chemotype sources for the species from North East India.
