Abstract:

In order to develop an optimal process for the ultrasonic-assisted extraction of flavonoids from Artemisia rupestris L., some crucial process conditions, namely ethanol concentration, material/liquid ratio and length of ultrasonic treatment were optimized using response surface methodology. Ethanol concentration of 76%, material/liquid ratio of 1:1 and length of ultrasonic treatment of 32 min were found optimum. Under the optimized conditions, the yield of flavonoids was 4.50%, with a 34% increase than before optimization.

Key words: Artemisia rupestris L., ultrasonic-assisted extraction, total flavonoids, response surface methodology
