Bhandare of Vietnam Giang M Phan and Son T Phan,* Faculty of Chemistry, College of Natural Science, Vietnam National University, 19 Le Thanh Tong Street, Hanoi Wilfried A König# , Institut für Organische Chemie, Universität Hamburg, D-20146 Hamburg, Germany Downloaded by [University of Connecticut] at 09:20 08 October 2014 Abstract The pleasant smelling flower essential oil of Artabotrys hexapetalus (L f.) Bhandare (Annonaceae) was analyzed by GC and GC/MS Twenty-six components of the oil including sesquiterpene hydrocarbons (33.3% of the oil) and oxygenated sesquiterpenoids (47.7%) were identified β-caryophyllene (11.4%) and caryophyllene oxide (31.5%) were identified as the major components of the oil Key Word Index Artabotrys hexapetalus, Annonaceae, essential oil composition, β−caryophyllene, caryophyllene oxide Plant Name Present work Artabotrys hexapetalus (L f.) Bhandare, Annonaceae (Vietnamese name Cay Mong Rong) Gas Chromatography: An Orion Micromat 412 instrument equipped with two fused silica capillary columns (25 m ì 0.25 mm, film thickness 0.15 àm) coated with non-polar CPSil-5-CB and more polar CPSil-19-CB (Chrompack), respectively, split injection and flame ionization detection, was used Injection and detector temperatures were maintained at 200°C and 250°C, temperature program 50°–230°C at 3°C/min, carrier gas H2 at 1.2 mL/min Gas Chromatography–Mass Spectrometry: A HewlettPackard HP 5890 gas chromatograph, coupled to a VG Analytical 70-250S mass spectrometer The GC was fitted with a fused silica capillary column coated with CPSil-5-CB (25 m × 0.25 mm, film thickness 0.15 µm) The GC operating conditions were identical to those described above The MS operating parameters were: ionization voltage, 70 eV; ion source temperature, 230°C; He was used as the carrier gas The oil was analyzed using GC on a non-polar fused CPSil-5CB and a more polar CPSil-19-CB capillary 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 a computer-supported spectral library under identical experimental conditions (1,2) Twenty-six components representing 81% of the oil were identified (Table I) The representative constituents of sesquiterpene hydrocarbons (33.3% of the oil) and oxygenated Source The fresh flowers of A hexapetalus were collected in Hoang Mai Village, Hanoi, Vietnam The plant material was identified by Dr Nguyen Hoanh Coi, Military Institute of Drugs Control, Hanoi, Vietnam, and voucher specimens are kept in the Herbarium of the Laboratory of Chemistry of Natural Products, Faculty of Chemistry, College of Natural Science, Vietnam National University, Hanoi, Vietnam Plant Part The fresh flowers were subjected to hydrodistillation for h to produce an oil of 0.94% yield based on the fresh weight The oil was dried over anhydrous sodium sulphate Previous work To the best of our knowledge, no chemical information on the essential oil from A hexapetalus has been reported *Address for correspondence # deceased Received: October 2005 Revised: January 2006 1041-2905/07/0005-0523$14.00/0­—© 2007 Allured Publishing Corp Vol 19, November/December 2007 Accepted: February 2006 Journal of Essential Oil Research/523 Phan et al Table I Percentage composition of the flower oil of Artabotrys hexapetalus Downloaded by [University of Connecticut] at 09:20 08 October 2014 Compound sesquiterpenoids (47.7%) were β−caryophyllene (11.4%) and caryophyllene oxide (31.5%), respectively Percentage composition (%)a) α-cubebene α-ylangene α-copaene β-elemene Sativene ylanga-2,4(15)-diene isocaryophyllene β-caryophyllene β-copaene α-humulene allo-aromadendrene γ-muurolene bicyclosesquiphellandrene α-muurolene (E,E)-α-farnesene γ-cadinene calamenene δ-cadinene α-calacorene caryophyllene oxide globulol humulene epoxide* 1-epi-cubenol 1(10)-spirovetiven-7β-ol selin-11-en-4-ol saccogynol 0.2 0.6 8.1 1.0 0.1 0.1 0.3 11.4 0.1 3.5 0.1 3.5 0.4 1.0 t 0.5 0.7 1.1 0.6 31.5 0.5 10.0 2.0 2.5 0.2 1.0 Acknowledgments This work was financially supported by Volkswagen Stiftung (Partnerschaftsvorhaben “Untersuchung ätherischer Öle Vietnams”) References D Joulain and W.A König, The Atlas of Spectral Data of Sesquiterpene Hydrocarbons E.B.-Verlag, Hamburg (1998) D.H Hochmuth, W.A König and D Joulain, MassFinder 2.3 Software and Data Bank, Hamburg (2003) Available at: www.massfinder.com t = trace (
