Organic solvents with different polarities were used to extract jujube polyphenols with high antioxidant activity.The extraction rates,total phenolic contents and antioxidant activities of the obtained extracts were compared.The results indicated that liquid-liquid extraction was a successful method for separating jujube polyphenols with different polarities.The stronger the polarity of organic solvent is,the higher the extraction rates,total phenolic contents and antioxidant activities of the extracts are.Most jujube polyphenols with high antioxidant activity are polar phenols.Therefore,weak polar polyphenols should be removed from crude extracts to achieve high antioxidant activity extract.
