On the other hand, the amount of carnosic acid extracted with ethanol is of the same order (70–80 mg/g dried extract) of that extracted by PLE, and higher than that extracted by longer ultrasonic proce- dures, 14 mg/g in 15 min, using ethanol as solvent a 50 C and a slightly higher solvent to leaves mass ratio (8:1) (Albu et al.,2004). Proestos and Komaitis (2008) also used MAE to extract anti- oxidants from rosemary and other aromatic plants, finding that water was a better solvent and its mixtures (60:40 v/v) with organ- ic solvents (acetone, methanol, ethyl acetate). They used dried and grinded rosemary obtaining an extract with a total phenol content of 20 mg GAE/g rosemary
