Effet du séchage sur le rendement des huiles essentielles de la plante Teucrium polium ssp. aurasianum Labiatae

Abstract

In the context of the exploitation of medicinal plants Algerian renowned for their therapeutic virtues, we are interested in the study of the plant Teucrium polium ssp. aurasianum Labiatae. The present work is devoted to the study of the effect of the drying of aerial parts on the yield of extraction, we have proceeded to the extraction of the essential oils of the plant by the technique for hydrodistillation. The plant is put to dry in the laboratory at ambient temperature for 8 day periods. The optimum yield is obtained at the 2th day of drying which gives an extraction efficiency of 0.585 %
