Abstract: To increase the extraction ratio of procyanidins from pueraria, the cellulase and pectase was used.The effects of amount of cellulase, amount of pectase, enzyme time and enzyme temperature on the yield of procyanidins were investigated. The results showed that the optimum conditions were as follows: the amount of cellulase was 0.40%, the amount of pectase was 0.69%, enzyme time was 92min, enzyme temperature was 65℃.Under the conditions, the yield of procyanidins was 5.02mg /g.The extract was then separated, and the antioxidant activities of procyanidins were evaluated, and the result showed that the procyanidins had high antioxidant activities.
