Optimization of Ultrasound-assisted Extraction of Carnosic Acid from Rosemary Leaves
摘要
Abstract
Carnosic acid, the key bioactive component, was extracted from leaves of roesmary ( Rosmarinus officinalis L.) using ultrasound-assisted extraction.The different factors such as ethanol concentration, variety of acid stabilizer, acid stabilizer dosage, ultronic 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.关键词
