Abstract

Flowers of Hypericum PerforatumL.plant (Hypericum SP genus , Hypericaceae family), was collected from two different regions of Tartous: Qadmus region (900m), Einaza region (450m),and the essential oil was extracted by Hydrodistillation using the Cleveger apparatus ,where the weight percentage of extracted essential oil stood at: (0.39%), (0.26%) forQadmus, Einaza region respectively.

The Chemical composition of essential oil obtained from flowers of Hypericum Perforatum L. was analyzed by gas chromatography technique associated with the mass spectrometry GC/MS.

The results of the analysis showed that the essential oil of Qadmus area contained 26 components,which accounted for (99.98%) of total essential oil. The main component was :   exo 6-carbonyl methoxy tricycle [2.2.1.0(2,7)] heptane, by 21.89%.

The results of the analysis showed that the essential oil of Einaza area contained 55 components, which accounted for (99.96%) of total essential oil. The main component was :

Trispiro(2.1.2.1.2.1)dodecane -4,8,12-trione, by 11.38%.
