| Abstract: | 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 t... |
