Abstract.The aim of the present study was to draw a comparative analysis of the content in flavones and polyphenols of the hydro alcoholic extracts obtained from two medicinal plants, namely artichoke (leaves) and respectively, licorice (root) according to the origin of the vegetal material and the method used in the preparation of the extracts.The plants used in the experiments are two indigenous medicinal plants belonging to wild and cultivated flora in Romania. Artichocke (Cynara scolymus) and licorice (Glycyrrhiza glabra) were purchased from three local companies trading medicinal plants: Plafar, Vitaplant and Franco Impex. It was evaluated the composition of the extracts in terms of the content of polyphenolic compounds expressed in caffeic acid and flavone compounds content expressed in rutin. Plant extracts were obtained by two different methods of preparation: ultrasonation and maceration with intermittent shaking.

Keywords: flavones, polyphenols, vegetal hidroalcoolic extracts
