Abstract
Volatile compounds from the berries of common juniper (Juniperus communis L.) were isolated by hydrodistillation, hexane extraction and supercritical CO2 extraction. The hydrodistillation yield was 2.17%, the hexane extraction yield 5.31 % and supercritical CO2 extraction yield 0.96%. Their compositions were compared using GC/M S as the method of analysis. Analyses reveal that samples differ quantitatively and qualitatively. The concentrations of monoterpene hydrocarbons (α-pinene, sabinene, myrcene) were higher in the hydrodistilled oil, while some less volatile compounds were present in extracts, especially in the hexane extract.
