The essential oils from seeds of nine Abies koreana specimens have been studied using GC-MS-FID and NMR methods, leading to the determination of 96 volatiles, which constituted over 99% of the oils. The hydrodistilled oils of fresh, resinous scent were isolated with yields in the range of 3.8-8.5%. The results showed that the essential oil of Korean fir seeds contained 70-95% monoterpenes and 1-20% oxygenated monoterpenes as the dominant groups. The numerous sesquiterpenes, diterpenes and their oxygenated derivatives constituted only 2-8% of the oil. The major component of the seed essential oil was limonene (41-72 g/100g); the laevorotary form of this terpene predominated. A. koreana seeds seem to be a rich source of both essential oil and (-)-limonene, whose average enantiomeric excess was above 95%.
