We investigated the enhancement of the antioxidant activities of the seeds of Prunus persica by several extraction processes: water extraction at 100℃ and 60℃, 70% ethyl alcohol at 60℃, microwave, ultrasonification at 90 KHz and high pressure at 500MPa. The extracts from high pressure extraction had the highest total phenol contents as 116.239 ㎍/㎎, which was two times higher than the extracts by water extraction at 100℃ in adding 1 ㎎/㎖. DPPH radical scavenging activity of the extracts from high pressure extraction also showed high ratio as 74.68% to ascorbic acid. DPPH of the extracts from another processes were observed as 44.56, 44.52, 47.01, 52.02, 61.42 and 63.34(%) from water extraction 100℃ and 60℃, 70% ethyl alcohol, microwave ,ultrasonification at 90 KHz, respectively. The extracts from high pressure extraction process were found to have the highest antioxidant activities among seven extraction processes because high pressure extraction could easily destruct cell membranes of hard seeds of Prunus persica and also elute high amounts of active compounds from them.
