ANALYSIS OF TERPENOIC COMPOSITION OF CONIFER NEEDLE OILS BY STEAM DISTILLATION/EXTRACTION, GAS CHROMATOGRAPHY AND GAS CHROMATOGRAPHY MASS SPECTROMETRY

摘要

The essential oils of Estonian spruce and pine needles have been analysed by a combination of steam distillation/extraction, GC and GC-MS. According to their monoterpene composition Estonian pines belong to a high carene chemotype with monoterpenes representing up to 85 % of total oil. Estonian spruce needle oil contains up to 70 % of oxygenated terpenes and more limonene and 1,8-cineole than the same spruce species [Picea abies (L.) Karst.] from other localities. A total of 60 components were identified. Coefficients of variation describe the range of component contents in individual trees within the population. [References: 17]
