Ultrasonic extraction of procyanidins from common buckwheat hull and antioxida-tion properties was studied in this paper .With the yield of procyanidins as index ,ultrasonic extraction of procyanidins from common buckwheat hull was optimized by the orthogonal ex-periments .Under the best conditions ,the antioxidation properties were illustrated by DPPH · .The results showed that under the best conditions of extraction temperature 60 ℃ ,etha-nol volume fraction 70% ,ultrasonic time 70 min ,solid-liquid 1∶30 ,ultrasonic power 200 W , the yield of procyanidins was 1 .311% .The results of antioxidant properties showed much better the antioxidant ability of procyanidins in common buckwheat hull on DPPH · scaven-ging ,and the antioxidant ability is strong than VC .
