Extraction and identification of some metabolites from three Algerian Sahara medicinal plants
Abstract

Metabolites are widely distributed in plant kingdom and have an ample range of biological properties. Several investigations have reported the medical and insecticidal activties.Thus, the objective of this study is to identify and qualify metabolites of 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 chemical study revealed the main metabolites which have biological activities as a part of an alternative to synthetic insecticides, including the presence of N-Butylbenzensulfonamide and Sulfoxycaprylicacid in the three plants. Both N-Carboxy-methionineresidue, butanoicacid and valine were found in Cotula cinerea and Caroxylon imbricatum (Forssk.). While, Artomunoxanthentrione, Glycoaldehyde, Indoline, Benzensulfonamide and Oxoproline were detected in extracts of Caroxylon imbricatum (Forssk.) and Tetraena alba (L.f.). Furthermore, Pyrroline is the only compound common in Cotula cinerea and Tetraena alba (L.f.). A fundamental and applied study on the active compounds of the analyzed plants leads to chemical entities that enter the strategy of a biological control.
