Phytochemical investigation and antioxidant activity of total phenols in the aerial parts of some Asteraceae family wild plants grown in western of Iraq

Noora Ibrahim issa, Zainab Yaseen Mohammed Hasan, Ashwaq Talib hameed.

In this study Phenolic compounds of aerial parts from four wild plants belongs to Asteraceae family that grown in Anbar land located western of Iraq was employed. These are: Achellia, Artemisia, Wild lettuce ( Lactuca ), and Silypum .Extraction was carried on by the method of cold maceration with 75% Ethanol. Qualitative estimation was done using thin layer chromatography technique (TLC) to detect types of simple phenols that these plants rich with. While total phenols of all these plants were estimated quantitatively through Gallic acid standard curve applied from Folin- ciocalteu colorimetric reaction for total phenols estimation. An investigation for the antioxidant activity using DPPH free radical scavenger was employed in this study. Qualitative results indicated that these plants may contained some important phenolic compounds such as Pyrogallole, cinammic acid, gallic acid and Hydroquinone in different range in each of the corresponding plant included in this study. Quantitatively; the result concluded that wild Artemisia possess the major content of total phenols reach to about 1.5% of plant dried leaves. The less phenolic content was about 0.224% found in wild Silypum.The antioxidant activity for the phenolic extract of the four plants was showed that Wild lettuce ( Lactuca ) extract possessed the potent activity , while the lowest activity was showed by wild Silypum.

Key words: Achellia, Artemisia, gallic acid, Lactuca, and Silypum.
