Chemical composition and antifungal activity of essential oils isolated from Juniperus Oxycedrus L.

ABSTRACT

The chemical composition of essential oils isolated from the leaves of Juniperus oxycedrus by hydrodistillation was analyzed by GC-MS. 42 compounds, representing 96.73% of total oil, were identified. J. oxycedrus oil was found to be rich in α-pinene (39.63%), manoyl oxide (12.34) and z-caryophyllene (4.1%) and characterized by relatively high amounts of monoterpenes hydrocarbons and sesquiterpenes. Results of the antifungal testing by in vitro contact assay showed that the oil significantly inhibit the growth of nine plant pathogenic fungi.
