Chemical Composition of Essential Oils of Artabotrys petelotii Merr.,Artabotrys intermedius Hassk., and Artabotrys harmandii Finet & Gagnep. (Annonaceae) from Vietnam

The chemical composition of essential oils of Artabotry spetelotii Merr., Artabotrys intermedius Hassk., and Artabotry sharmandii Finet & Gagnep. (Annonaceae) collected from Vietnam and determined by GC-FID and GC-MS, are being reported. The main compounds of the leaf of A. petelotti were elemol (19.4 %), cis-beta-guaiene (9.2 %), delta-cadinene (8.4 %) and delta-elemene (5.5 %), while the stem bark comprised mainly of elemol (32.7 %), delta-cadinene (11.9 %) and spathulenol (9.6 %) as compounds of significant quantities. On the other hand, delta-3-carene (19.1 %), alpha-gurjunene (10.7 %) and alpha-zingiberene (6.3 %) were the major constituents of the leaf oil of A. intermedius. The stem was rich in delta-3-carene (29.9 %), germacrene D (15.1 %) and alpha-amorphene (8.0 %). A. harmanddii yielded oil in which the major components were spathulenol (17.4 %), aromadendrene epoxide (12.2 %), gamma-elemene (7.1 %) and isospathulenol (5.6 %). The compositional patterns of these oil samples are being reported for the first time.
