Determination of the lipid compounds of Aristolochia longa L. from Algeria.

The present work joins in an initiative, for main objective the determination and the biochemical characterization of a medicinal plant with wide use in certain regions of Algeria. Samples of Aristoloche were collected from the region of Medea (West of Algiers). By stream training we obtained essential oil and by hydro distillation concrete of the stalks, rhizomes and leaves. With theTLC we detect and confirm the presence of esters of Methyl in our samples. Besides, Gaz chromatography (CG), allowed us to determine the main group of fatty acids characterizing our essential oil and diluted concrete. An important proportion was showed by the palmitic acid with 22, 97 %, linoleic acid demonstrate a rate of 11, 50 %, oleic acid illustrate 7,24 %.
