Zaid M. Najah* and Najla A. Algaw

ABSTRACT

The chemical composition and antioxidation ability of Scorzonera Undulata plant was investigated. Phytochemical screening tests of ethanolic extract of aerial part of the plant revealed the presence of all known phytochemical compounds; alkaloids, carbohydrates, glycosides, saponins, phytosterols, phenols, tannins, flavonoids, proteins, terpenes and quinones. The plant showed moderate antioxidation ability with IC50 of 33.37 μg/ml. GC-MS technique was also used for chemical composition analysis, the results showed presence of fiftyone compounds with very diverse chemical classes including fatty acids and their esters, long chain hydrocarbons, long chain alcohols and heterocyclic compounds. The most abundant compounds were: 17-Octadecynoic acid, (E)-9-Tetradecen-1-ol, acetate, E-7-Tetradecenol, (Z,Z)-9,12-Octadecadien-1-ol, 4,9-Tetradecadien-1-ol, Deoxyspergualin, Undecane, 6,6-Methyl-2-Methylundecane-6,6, Trans-3-Cyclopentene-3,5-Diol.

Keywords: Scorzonera Undulata, GC analysis, Fatty acid esters, Bioactive compounds.
