2.2.4.2. Microwave assisted extraction
Rosemary leaves were immersed into the solvent and submitted to microwave during 30 min, using a MW reactor (900 W, EOS-GR, Milestone, Italy) and a reflux apparatus. Microwave power was fixed at 210 W (1 W/g). Extraction was done at boiling temperature (78 °C) and atmospheric pressure. Each experiment was performed in triplicate.
