Four essential oils obtained from the aerial parts of Baeckea frutescens harvested in three provinces of Vietnam were analysed using GC, GC–MS and NMR spectroscopy. Forty‐seven components, which represented 90–97% of the global composition, were identied. Two samples were characterized by the pre‐eminence of tasmanone, a non‐terpenic triketone, which accounted for 22.9% and 24.3%, respectively, of the chemical com‐position and which was fully characterized using two‐dimensional NMR spectroscopy. The two remaining samples were respectively characterized by high contents of p ‐cymene, α ‐thujene and 1,8‐cineole for one sample and β ‐pinene, 1,8‐cineole and α ‐pinene for the second sample. From these results and the literature data, it appears that B. frutescens essential oil exhibits high chemical variability. Copyright © 2004 John Wiley & Sons, Ltd.
