The essential oils from the bark, leaves, buds, and flowers (full bloom) of Mesua ferrea Linn., Guttiferae, were analyzed by high resolution GC and HRGC/MS, Between 32 and 50 components were identified in the oils from the different plant parts, accounting for 82% to 97% of the total yields. Substantial variations in the relative concentrations of several constituents were noticed. The bark oil was rich in (E)-a-bisabolene (31.3%) and a-seHnene (12.2). The predominant components in the oils of tender and mature leaves were a-copaene 09.3% and 9,9%) and beta-caryophyllene 08.8% and 26.00/0), The bud and flower oils also contained alpha-copaene (28.7% and 20.2%), and in addition germacrene D (9.0% and 16.1%).
