Study on Optimization of Ultrasound-Assisted Extraction of Polyphenols from Rumex Hanus and Their Effects on α-glucosidase Inhibitory Activity
This study extracted polyphenols from Rumex Hanus using ultrasound and studied their effects on α-glucosidase inhibitory activity.Based on the single factor test,the ultrasound-assisted extraction of polyphenols from Rumex Hanus were optimized by response surface method.The optimum conditions for ultrasound-assisted extraction were ethanol volume fraction content 60%,ultrasonic power 250 W,extraction time 31 min.Under these conditions,the yield of polyphenols was(12.55±0.26)%.Polyphenols from Rumex Hanus have higher α-glucosidase inhibitory activity,the IC50 was 1.73 mg/mL.The results can provide reference for the extraction of polyphenols and the development of its function.
