영문 초록

Apple and pear are popular fruits consumed in Korea and are common fruit in daily diet. In order to compare theantioxidant activity of the apple and pear peels, total polyphenol contents, total flavonoid contents, ABTS+ free radicalscavenging activity, and DPPH free radical scavenging activity were measured from hot water, ethanol, and methanolextracts of the two fruit peels. The total polyphenol and flavonoid contents were highest in 95% methanol extracts of theapple peelsand 70% ethanol extract of the pear peels, respectively. Total polyphenol contents of the pear peels were higherthan that of apple peels, and total flavonoid contents of the apple peels were higher than that of pear peels. The apple andpear peels had the highest ABTS+·and DPPH free radical scavenging activity in 95% methanol extracts and 70% ethanolextracts, respectively. ABTS+·and DPPH free radical scavenging activity of pear peels was higher than that of apple peels,and the DPPH free radical scavenging activity of apple and pear peels were detected in hot water, 95% methanol, and 70%ethanol extracts, respectively. Ascorbic acid, a synthetic antioxidant used as positive control, had significantly higherscavenging activity than the apple and pear peels. In conclusion, the apple and pear peelshave great potential as naturalantioxidants. Therefore, above results should be considered to provide the possibility for the development of high functionalantioxidants.
