Study of the Physicochemical Properties of Lavender Essential Oil (Lavandula Stoechas)

For many years, the quest for new medicinal molecules of natural origin has been based on medicinal plants and ethnobotanical studies, which make it possible to carry out inventories of plants in a given region, determining their qualities through phytochemical and pharmacological studies. As a result, the development of natural resources is becoming an increasingly important concern in many countries. Morocco, a country renowned for its natural resources, boasts a singularly rich and varied flora. The various natural substances derived from plants have a wide range of uses in traditional health care systems and in industries such as food, cosmetology and dermopharmacy. Among these substances are secondary metabolites such as essential oils, which are particularly well known in therapeutics. In this context, and as part of our work on medicinal plants and essential oils, we were interested in extracting and processing the essential oil of Butterfly Lavender harvested in the Oulmes area. In this way, we were able to determine physico-chemical properties such as density, refractive index, acid number and ph measurement, which gave us a great deal of information about this oil.
