Extraction of essential oils of olive flowers

Hydrodistillation of dried flowers of selected olive varieties was performed in a Clevenger apparatus (for two hours and 30 minutes) in the laboratory of the Institute for Adriatic Crops and Karst Reclamation, The essential oils obtained by the hydrodistillation process were dried with anhydrous sodium sulfate. Samples of essential oils prepared in this way are stored in glass bottles at a temperature of 4┬░C. These essential oils will determine the profile of volatile substances, which could be responsible for attracting the olive moth (Prays oleae Bern.).
