تحديد تركيب الزيت العطري، و الكشف عن المستقلبات الثانوية لنبات القرصعنة المنتشر في سورية

الملخص EN

Eryngium creticum is widespread in Syria as it grows in variant environments : mountains, semidesert and saline environments.

It has a wide range of biological and pharmacological activities as well as diverse traditional uses.

Since knowledge of the chemical constituents of plants has medical and economical importance, especially essential oils, this study aimed to screen the secondary metabolites of E.

creticum and to determine its essential oil composition.

Results : Qualitative detection of the most important plant secondary metabolites was conducted, and the results showed that the plant contains flavonoids and coumarins with absence of saponins, tannins, alkaloids, and anthraquinones.

Detection of cardiac glycosides reactions was positive but it is likely to be false positivity.

The essential oil of aerial parts of E.

creticum was recovered by Hydrodistillation and the yield was 0.1 % V/W.

It was analyzed by Gas Chromatography coupled with Mass Spectrometer (GC-MS).

62 compounds were identified with Falcarinol having the highest percentage (13.5 %), then alpha-Farnesene with a percentage of (11.9 %), and finally Spathulenol (+) with percentage of (11.5 %).

Sesquiterpenes and their oxygenated derivatives came with the highest percentage of compounds.

These results show that E.

creticum is a source of some groups of plant secondary metabolites, and it contains an essential oil rich in volatile compounds with a wide range of activities.
