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

Plant Name
Artabotrys hexapetalus (L f.) Bhandare, Annonaceae
(Vietnamese name Cay Mong Rong).
Source
The fresh flowers of A hexapetalus were collected in Hoang
Mai Village, Hanoi, Vietnam The plant material was
identi-fied 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 8
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
Present work
Gas Chromatography: An Orion Micromat 412 instrument equipped with two fused silica capillary columns (25 m × 0.25
mm, film thickness 0.15 µm) 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 Hewlett-Packard 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 tem-perature, 230°C; He was used as the carrier gas
The oil was analyzed using GC on a non-polar fused
CPSil-5-CB and a more polar CPSil-19-CPSil-5-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

sesquiterpenoids (47.7%) were β−caryophyllene (11.4%) and caryophyllene oxide (31.5%), respectively
