Pimpinella anisum L. (anise) seeds have been widely used as a culinary ingredient as well as traditional remedies for the treatment of different disorders in the folk medicine systems of different civilizations. Its essential oil show many properties and is already well studied and used. The lipid fraction of the seeds has also already been investigated. Petroselinic acid was the most prevalent fatty acid in anis oil seeds. This one also presents several properties. Nowadays, fixed oils are extracted with the help of petrosolvents. This raise issues regarding environment and security, but also public health. Regulations are more and more strict and alternative more and more searched. In general, those ones consist in the use of substitution solvents. Thus, the purpose of this work was designed to evaluate the performances of a green solvent compared to n-hexane in aniseed oil extraction
