Pomegranate peel polyphenol not only has significant anti-oxidation and scavenging free radical effects, but also inhibits the oxidation of low-density lipoprotein cholesterol, prevents atherosclerosis, lowers blood fat, lowers blood pressure, and reduces the incidence of gastric ulcer. Therefore, pomegranate peel polyphenols are expected to be widely used in food, medicine and cosmetics.

The macroporous adsorption resin has the advantages of high selectivity, large adsorption capacity, fast adsorption speed, easy desorption, and low cost. In recent years, it has been applied more and more in the separation and purification of pomegranate peel polyphenols, showing a good development trend.
