دراسة التركيب الكيميائي للزيت العطري و الكشف عن المستقلبات الثانوية في نبات جعبة الراعي المنتشر في دمشق

Abstract EN

Capsella bursa-pastoris is a wild herb with high nutritional value that can be eaten raw or cooked in some countries; it's also used in the traditional medicine of many countries as anti bleeding and to Relieves inflammation.

Many researchers from several countries studied its chemical composition and pharmacological effects.

However, there is no study in Syria on this plant, although it is one of the wild plants widespread in it.

Therefore, this study aimed to identify the chemical composition of its essential oil, and the secondary metabolites present in its aerial parts.

The essential oil was obtained from the aerial parts of the plant by water distillation and then analyzed by gas chromatography associated with mass spectrometry.

It was found that the oil contains thirty-eight compounds .The main compounds were Hexahydrofarnesyl acetone (Phytone) 20.2%, Diacetyl-4,4',6,6'-tetramethoxy-2,2'-biphenyldiol (8.46%), Diisopropyl methylphosphonate (6.45%) and Beta-Ionone (5.24%).

The detection reactions were applied to screen for secondary metabolites in the aerial parts of the plant.

The results showed the presence of flavonoids, coumarins and alkaloids, while the result was negative for saponins, cardiac glycosides, anthraquinones and tannins.
