Abstract
The essential oils in fresh needles and green and mature berries of Juniperus oxycedrus L. (Cupressaceae) were analyzed by GC–MS. A total of 36 compounds were identified from needles, representing 94.91% of the total oil. 15 compounds were identified in the green berry oil and 22 in the mature berry oil, which accounted for 94.33 and 90.94% of the total oil composition. The major component was α-pinene. The glycosidically bound volatile compounds amounted to 21 mg kg −1 in needles and 4 mg kg −1 from green berries. Only traces of aglycones were identified in mature berries. Sixteen volatile aglycones were identified in needle sample with 2-hydroxy-5-methylacetophenone as major component. A total of nine aglycones were identified in green berries. The major aglycones were 3-phenyl-2-propen-1-ol and myrtenol. There was no similarity between the glycosidically bound aglycones and the corresponding free compounds found in the essential oil.
