EXTRACTION DES HUILES ESSENTIELLES DE QUELQUES PLANTES

Abstract

The richness of Algeria's flora no longer needs to be demonstrated. Like other areas, Western Algeria and in particular the Mostaganem region is characterized by a flora particularly rich in medicinal plants. The preservation of this plant biomass constitutes a crucial issue on a national scale. In this work we have a phytochemical study; as well as the extraction of essential oils from the aerial parts of Rosmarinus officinalis and Capparis spinosa; ziziphus lotus; and vegetable oils of salvia hispanica and Seseli montanum with two methods; steam entrainment and soxhlet extraction. The aim of our study is to obtain a good yield of oils extracted from different parts of plants (leaves, roots, grains). The results obtained are respectively: 0.12% for Rosemary, and 15.68% and 26.34% for salvia hispanica and seseli montanum.
