摘　　要：Objective:To investigate the physicochemical properties of unripe peach-Pruuns persica cv.Mibaekdo(Mibaekdo) and Prunus persica cv.Nagasawa Hakuho(Nagasawa Hakuho) as an alternative to fowl supplement while Japanese apricot(Prunus mume cv.Backaha)(Backaha) was used as a control sample.Methods:The unripe fruits were analyzed for soluble solid(Brix).titratable acidity.pH,total polyphenol content,1,1-diphenyl-2-pierylhydrazyl(DPPH) radical scavenging activity,amygdalin content,free amino acid content,organic acid content,free sugar content,and α-amylase activities.Results:Total polyphenol content of unripe peach ranged between 137.27-151.64 μg/g whereas that of apricot was 160.73 μg/g.DPPH radical scavenging activities of Rackaha was the highest189.16%.) followed by Mibaekdo(85.03%) and Nagasawa Hakuho(41.30%).The highest amount of oxalic acid 1612.8 mg/100 g) was observed in Mibaekdo while that of Nagasawa llakuho and Backaha were(184.6±18.1) and(334.8±16.1) mg/100 g,respectively.Amygdalin contents of Mibaekdo.Nagasawa Hakuho and Backaha were 486.61,548.60 and 174.28 μg/g,respectively.Conclusions:The results suggest that the unripe fruit of peach has a significant biochemical potential of using as a food supplement with potential health benefit for human health.Objective:To investigate the physicochemical properties of unripe peach-Pruuns persica cv.Mibaekdo(Mibaekdo) and Prunus persica cv.Nagasawa Hakuho(Nagasawa Hakuho) as an alternative to fowl supplement while Japanese apricot(Prunus mume cv.Backaha)(Backaha) was used as a control sample.Methods:The unripe fruits were analyzed for soluble solid(Brix).titratable acidity.pH,total polyphenol content,1,1-diphenyl-2-pierylhydrazyl(DPPH) radical scavenging activity,amygdalin content,free amino acid content,organic acid content,free sugar content,and α-amylase activities.Results:Total polyphenol content of unripe peach ranged between 137.27-151.64 μg/g whereas that of apricot was 160.73 μg/g.DPPH radical scavenging activities of Rackaha was the highest189.16%.) followed by Mibaekdo(85.03%) and Nagasawa Hakuho(41.30%).The highest amount of oxalic acid 1612.8 mg/100 g) was observed in Mibaekdo while that of Nagasawa llakuho and Backaha were(184.6±18.1) and(334.8±16.1) mg/100 g,respectively.Amygdalin contents of Mibaekdo.Nagasawa Hakuho and Backaha were 486.61,548.60 and 174.28 μg/g,respectively.Conclusions:The results suggest that the unripe fruit of peach has a significant biochemical potential of using as a food supplement with potential health benefit for human health.
