A combination of GC and MS was used to identify 40 different compounds in the essential oil of Thuja occidentalis L. foliage samples collected from mid-Michigan (USA). The essential oils were obtained by three different methods: pilot scale steam distillation, cool hexane solvent extraction, and laboratory steam microdistillation. By all three methods the major compounds identified were alpha-thujone (39-56%), fenchone (6.0-15.0%), beta-thujone (7.2-11.0%), sabinene (2.1-8.9%), beyerene (1.30-5.95%), bornyl acetate (1.20-4.38%) and camphor (1.5-3.3%). Fifteen diterpenes were found, eight of which were identified for the first time in the oil of T. occidentalis foliage. Variations in the oil composition as a function of isolation technique are also reported.
