Essential oils from the bark and flowers of Cinnamomum bejolgbota (Buch.-Ham.) Sweet, Lauraceae, obtained from two different locations of Assam, India, were investigated by a combination of high resolution GC 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 0.6% from the two locations (Jorhat and Sibsagar, respectively). Between 32 and 75 compounds have been identified, accounting for 92.0-99.7% of the various oils. The major constituents of the bark oils from Jorhat and Sibsagar were 1.8-cineole (31.3% and 7.2%), alpha-terpineol (21.3% and 12.7%) and linalool (20.0% and 19.9%). The predominant components in the flower oils were alpha-pinene (42.9% and 17.0%) and beta-pinene (24.9% and 17.2%). The chemical composition of the oils from the two different places exhibited marked variations.
