Detection of Active Compounds in Residues some Species of Plant, Isolation and

The research aims to the guarantee detection of some active compounds in plant residues for crops Wheat (Triticum aestivum L.), Barely (Hordeum Spp. Desf.),Corn )Zea mays L.), Sunflower (Helianthus annuus L.) using the appropriate chemical reagents, were separated and some estimate Amer M.

The results of initial qualitative statements showed presence most of the secondary metabolic compounds which includes (glycosides and alkaloids, tannins, flavonoids, terpenes, steroids, saponins, resins) in the sun flower remnants, while the results of detecting the presence of steroids in the remnants of barley and Corn did not show, as did not give turbines and steroid positive and resins when detected in the remnants of wheat, were also measured quantity (glycosides and alkaloids, tannins, flavonoids) and the results showed that the highest concentration of (alkaloids, tannins, flavonoids) was in the sun flower residues, while the highest concentration of Glycosides was in the residues of barley. 2. The results of the analysis devise chromatography High performance liquid HPLC showed presence 5 phenolic compounds, in residues of wheat (Hydroquinone, PHydroxy benzoic acid, Quercetin, Salicylic acid, Rutin), two compounds in barley residues(Hydroquinone, Caffiec acid), 5 compounds in Corn residues(Caffiec acid, Hydroquinone, Resorcinol, Rutin, Vanillin), but the sun flower residues continued(Quercetin, Resorcinol, Rutin, Vanillin).
