ion source temperature, 230°C; He was used as the carrier gas The oil was analyzed using a dual GC on a non-polar polar CPSil-5-CB and a more polar CPSil-19-CB columns of identical dimensions and GC/MS on a CPSil-5-CB column Retention indices and mass spectra of the constituents were compared with those of authentic samples and computer-supported library spectra generated under identical experimental conditions (1) Twenty-five compounds, representing 86.4% of the oil, were identified (Table I) 1,8-Cineole (45.1%) is the main component of the oil Acknowledgments Present Work Gas Chromatography: An Orion Micromat 412 instrument equipped with two fused silica capillary columns (25 m x 0.25 mm, film thickness 0.15 mm) coated with CPSil-5-CB and CPSil-19-CB (Chromapack), respectively, split injec- We thank the VolkswagenStiftung (Partnerschaftsvorhaben “Untersuchung ätherischer Öle Vietnams”) for financial support to this work References D.H Hochmuth, W.A König and D Joulain, MassFinder 2.3 Software & Data Bank, Hamburg (2003) Available at: www.massfinder.com *Address for correspondence Received: October 2005 # deceased Revised: January 2006 1041-2905/07/0005-0507$14.00/0­—© 2007 Allured Publishing Corp Vol 19, November/December 2007 Accepted: February 2006 Journal of Essential Oil Research/507 Phan et al Table I Constituents of the essential oil from the rhizomes of Alpinia henryi Downloaded by [University of Colorado at Boulder Libraries] at 13:38 20 December 2014 Compound 2-hexanol α-pinene camphene β-pinene myrcene α-phellandrene δ−3-carene p-cymene 1,8-cineole γ-terpinene terpinolene α-fenchol camphor isoborneol borneol terpinen-4-ol α-terpineol α-fenchyl acetate nerol geraniol isobornyl acetate 2-undecanone 2-undecanol 4,6-undecandien-2-one 2-tetradecanone a) Means of identification MS, Ri MS, Ri MS, Ri MS, Ri MS, Ri MS, Ri MS, Ri MS, Ri MS, Ri MS, Ri MS, Ri MS, Ri MS, Ri MS, Ri MS, Ri MS, Ri MS, Ri MS, Ri MS, Ri MS, Ri MS, Ri MS, Ri MS, Ri MS, Ri MS, Ri Percentage composition (%)a 1.8 2.0 1.5 4.1 3.7 0.3 0.1 4.2 45.1 0.2 0.8 0.5 3.0 0.8 4.4 1.6 4.9 2.2 1.4 1.4 0.4 0.5 0.3 1.1 0.1 Relative percentages were obtained on the GC CPSil-5-CB column 508/Journal of Essential Oil Research Vol 19, November/December 2007 ...A henryi J Essent Oil Res., 19, 507–508 (November/December 2007) Chemical Composition of the Essential Oil from the Rhizomes of Alpinia henryi K Schum of Vietnam Giang M Phan...
