【摘要】 [Objective]To explore the comprehensive extraction method of anthocyanin in tea and observe its antioxygenation.[Methods]Anthocyanin in tea was extracted and separated by ultrasonic-assisted acidic ethanol extraction.The optimal extraction condition was determined by single factor test and orthogonality analysis.Coarse extract of anthocyanin was obtained.[Results]High content of anthocyanin could be obtained when ethanol concentration was 80%,acid concentration was 0.6%,liquid ratio was 1∶20(g/mL)and extracted 3 times.The extraction ratio of anthocyanin reached 3.782 5 mg/g.The antioxidant abilities of anthocyanin and Jinxuan tea were compared by FRAP,DPPH and ABTS method.And as a result,it indicated that the antioxidant ability of anthocyanin was stronger and anthocyanin was a good free-radical scavenger.[Conclusions]The research could provide basis for expending source of anthocyanin,identifying components and developing tea health product.
