ABSTRACT: More than 30 components have been identified in the essential oil of Altingia siamensis Craib. resin from Vietnam by a combination of high resolution GC and GUMS. The major compounds were found to be a-copaene (9.6%), a-humulene (8.5%), junenol (6.8%), P-caryophyllene (6.6%), P-bisabolene (5.5%) and (E,E)-a-farnesene (5.0%). The oil consisted for more than 52% of sesquiterpene hydrocarbons.

KEY WORD INDEX: Altingia siamensis, essential oil composition, sesquiterpenes.

PLANT NAME: Altingia siamensis Craib. (Syn. Altingia gracilipes Hemsl.), Hamamelidaceae R. Br.

SOURCE: Wild plants from the Gungr6 area in the Di Linh &strict, L2m D6ng province. Specimen have been deposited in the Botanical Garden Herbarium of H6 Chi Minh City and in the Herbarium of the DB Lat University.

PLANT PART: Resin of this plant, collected in 1992. Steam &stillation produced an oil in 15% yield.

PREVIOUS WORK Reports on the chemical composition of the volatile oils from this plant have not been found by the authors.

528 JOURNAL OF ESSENTIAL OIL RESEARCH

PRESENT WORK: The resin oil obtained from the aerial parts of A. siainensis Craib. was analyzed by a combination of capillary GC and G U M S as described previously (1). The constituents were identified by library searching their 70 eV EI mass spectra and retention indices. Quantitative data were obtained by Flame Ionization Detection and electronic integration, neglecting FID response factors. The compounds identified in the oil of A. siainensis Craib. resin from Vietnam are (listed in the order of elution from an OV-1 column):

a-thujene (trace) a-pinene (4.1%) P-fenchene (0.5%) camphene (1.8%) P-pinene (2.2%) p-menth-2-ene (0.3%) p-cymene (3.6%) limonene (0.1%) acetophenone (0.2%) camphor (0.7%) borneol(O.l%) terpinen-4-01 (0.3%) a-terpineol (trace) myrtenol(O.2%) a-cubebene (0.3%) a-copaene (9.6%) P-bourbonene (1.7%) P-cubebene (1.8%) trans-a-bergamotene (1.4%)

P-carophyllene (6.6%) cis-a-bergamotene (4.7%) unknown MW 206 (3.8%) a-humulene (8.5%) (Z)-p-farnesene (2.0%) y-muurolene (1.0%) a-curcumene (1.5%) (E)-P-farnesene (1.6%) a-muurolene (0.5%) (E,E)-a-farnesene (5.0%) P-bisabolene (5.5%) calamenene (0.5%) unknown MW 206 (3.5%) 6-cadinene (1.4%) spathulenol (1.0%) caryophyllene oxide (4.6%) unknown (3.2%) junenol(6.8%) other compounds (9.3%)

This result shows that the oil of A. siamensis Craib. resin is a promising source for fixative components.

ACKNOWLEDGMENTS: The authors would like to thank Dr. D. Q. Huy (EDC International fellow at the Eindhoven University) for the quantitative analysis, and Dr. J. A. Rijks (chairman of the EDC International Foundation) for supporting this work.
