Ultrasonic-Assisted Extraction of Chlorogenic Acid from Capillary Artemisia with Natural Deep Eutectic Solvent-Functionalized Cellulose

초록

Ultrasonic-assisted extraction methods have been applied in many fields in recent decades. In this study, chlorogenic acid was isolated from capillary artemisia ultrasonically using the designed poly (natural deep eutectic solvents-ethylene glycol dimethacrylate) cellulose. The actual quantity of chlorogenic acid extracted was 62.83 mg g(-1 )dry powder using the following optimal conditions: raw material to liquid ratio of 1:40 g mL(-1), extraction temperature of 80 degrees C, ultrasonic power of 160 W, and extraction time of 40 min. The limit of detection for chlorogenic acid in capillary artemisia was 0.14 mu g mL(-1), and the intraday and interday precision values as the relative standard deviation (n = 6) after spiking with 5, 100, and 500 mu g mL(-1)were both less than 4.21%. This paper reports an effective method that provides facile operation, is low cost, and has excellent selectivity for chlorogenic acid in capillary artemisia.
