Carnosic acid, the key bioactive component, was extracted from leaves of rosemary (Rosmarinus officinalis L.)using ultrasound-assisted extraction. The different factors such as ethanol concentration, variety of acid stabilizer, acid stabilizer dosage, ultrasonic frequency, ultrasonic power, ultrasonic extraction time and the solid-liquid ratio were studied. The content variations of carnosol, rosmarinic acid, oleanolic acid and ursolic acid were also examined.The experimental results for 5.0 g rosemary leaves showed that the optimum ultrasonic extraction conditions at room temperature were: ethanol solution concentration 75 %, acid stabilizer 3 g hydrochloric acid, ultrasonic frequency 28 kHz, ultrasonic power 200 W, ultrasonic extraction time 40 min, solid-liquid ratio(g: g)1: 16. The extraction rate of carnosic acid reached 18.64 mg/g under the above extraction conditions.
