Abstract

The essential oils from leaves, stems, flowers and rhizomes of Etlingera elatior, an aromatic plant that are widely used in traditional  medicine  and  as  a  flavour  in  local  dishes  were  extracted.  The  essential  oils  were  extracted  using  the hydrodistillation method and analysed by  GC-MS.   The percentage yield of  volatile constituents of the leaves, stems, flowers and rhizomes were 0.0735%, 0.0029%, 0.0334% and  0.0021%, respectively. The leaf essential oil contained  ß- pinene (19.7%), caryophyllene (15.36%) and (E)-ß-farnesene (27.90%) as major compounds whereas the stem essential oil were largely dominated by  1,1-dodecanediol diacetate (34.26%) and (E)-5-dodecane (26.99%). The essential oils of the flowers and rhizomes contained the major compounds 1,1-dodecanediol diacetate (24.38% and 40.37% respectively) and cyclododecane (47.28% and 34.45% respectively).
