Kam and Elettariopsis rugosa (Y.K. Kam) C.K. Lim were analyzed by capillary GC and GC/MS. The oils of E. smithiae were dominated by monoterpenoids, the major components were geranial (38.1%) and neral (29.1%) in the leaf oil, and camphene (22.9%) and α-fenchyl acetate (15.7%) in the oil from the rhizomes and roots. The leaf oil of E. rugosa contained high levels of sesquiterpenoids, particularly spathulenol (29.5%), while the oil of the rhizomes and roots contained mainly monoterpenoids, with β-phellandrene (26.2%) and camphene (15.2%) being clearly the two most abundant components.

Essential oils of etlingera elatior (Jack) R. M. smith and etlingera littoralis (Koenig) giseke / K.C. Wong in The journal of essential oil research, Vol. 22 N° 5 (Septembre/Octobre 2010)

M. Smith and a white-flowered variety known as Thai queen, and Etlingera littoralis (Koenig) Giseke were analyzed by capillary GC and GC/MS. The oils of E. elatior were dominated by mono- and sesquiterpenoids, with the major components being myrcene (13.5%), α-humulene (11.8%) and β-caryophyllene (10.7%) in the leaf oil, and camphene (18.0%) and β-pinene (16.9%) in the oils from the rhizomes and roots, respectively. The oil profiles of the Thai queen cultivar were similar, except for a much higher level of α-pinene (24.4%) and a lower concentration of myrcene in the leaf oil, and markedly increased proportions of dodecanol and dodecanal in both the oil of the leaves (18.9% and 15.9%, respectively) and that of the rhizomes and roots (12.9% and 10.6%, respectively). The oils of E. littoralis were characterized by high levels of phenylpropanoids, principally (E)-methyl isoeugenol at 37.7% in the leaf oil and 58.1% in the oils from the rhizomes and roots, the complete absence of non-terpenic aliphatic alcohols and aldehydes, and the occurrence of 8(14), 15-sandaracopimaradien-3β-ol and 7, 15-isopimaradien-3β-ol.
