Composition of the bark and flower oils of Cinnamomum bejolghota (Buch.-Ham.) sweet from two locations of Assam, India

Essential oils from the bark and flowers of Cinnamomum bejolghota (Buch. Ham.) Sweet, Lauraceae, obtained from two different locations of Assam, lnelia, were investigated by a combination of high resolution Ge and GC/MS. The bark from both areas yielded the same quantity of oil (0.08%), whereas the oil yield from the flowers varied between 0.13% and 0.60/0 from the two locations (Jorhat and Sibsagar, respectively). Between 32 ancl 7'5 compounds have been identified, accounting for 92.0-99.7% of the various oils. The major constituents of the bark oils fromJorhat and Sibsagar were I,S-cineole (31.3% and 7.2%), a-terpineol (21.3% and 12.7%)) and linalool (20.0% and 19.9%). The predominant components in the flower oils were a-pinene (42.9% and 17.0%) and p-pinene (24.9% and 17.2%). The chemical composition of the oils from the two different places exhibited marked variations
