摘要：
The composition of the volatile oil of the common juniper (Juniperus communis L.) from Estonia was analyzed by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). The yield and composition of the oil obtained by different methods (micro-distillation and extraction, SDE, and supercritical carbon dioxide extraction, SFE) from various parts of juniper (berries, needles) were compared. The oil yield ranged from 0.7 to 2.1%. The content of alpha-pinene of juniper-berry essential oil was 47.9, that of juniper needleoil, 36.4%. The oil yields and composition obtained by SDE and SFE from juniper needles were similar. The oil obtained by SFE from juniper berries contained more sesquiterpenes and high boiling compounds than that obtained by SDE.
