Cotula Cinerea

Spontaneous plants metabolites are more widespread for their properties and biological functions. Also, natural products have reminded diverse scientists to take a delight in their medical and insecticidal applications linked to the environmental. A variety of metabolites have a defensive function for the plants. Thus, three spontaneous plants: Caroxylon imbricatum, Tetraena alba and Cotula cinerea collected from two ecotypes and analyzed by two known conventional methods:Gas Chromatography‐Mass Spectrometry GC QTOF(quadrupole time of flight )_MS and Liquid Chromatography-Mass spectrometry LCQTOF(quadrupole time of flight )_MS. The investigation conducted out on the identification and quantification of metabolites revealed the main metabolites which have biological activities as a part of an alternative to synthetic insecticides. The chemical study showed the presence of N-Butylbenzensulfonamide and Sulfoxycaprylicacid in the three plants. N-Carboxy-methionineresidue, Butanoicacid and Valine were found in those of Cotula cinerea and Caroxylon imbricatum (Forssk.). Artomunoxanthentrione, Glycoaldehyde, Indoline, ,Benzensulfonamide and Oxoproline were detected in extracts of Caroxylon imbricatum (Forssk.) and Tetraena alba (L.f.) In addition, Pyrroline is the only compound common in Cotula cinerea and Tetraena alba (L.f.).
