영어 초록

This study was performed to investigate the antioxidant effects of 4 citrus fruits including Hallabong,Cheonhyehyang, Cheonggyeon, and Jinjihyang. In this study the citrus fruits were separated in three parts of peel, pulp segment membrane (PSM), and pulp and extracted with methanol, then concentrated using a rotary vacuum evaporator. Total polyphenol contents ranged 23.497~42.341 mg/g in peel, 13.285~21.872 mg/g in PSM and 6.333~11.627 mg/g in pulp of the citrus fruits. The total polyphenol contents were highest in the peel and PSM of Jinjihyang and in the pulp of Cheonhyehyang. 1,1-diphenyl-2picryl hydrazyl (DPPH) radical scavenging activities were highest in the peel and PSM of Jinjihyang and in the pulp of Cheonhyehyang. 2,2’-Azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging capacities were also highest in the peel and PSM of Jinjihyang and in the pulp of Cheonhyehyang. Reducing powers were highest in the peel of Cheonggyeon, in the PSM of Jinjihyang,and in the pulp of Cheonhyehyang. There were significant correlations in between total polyphenol contents and the radical scavenging activities, and reducing power each other. These results indicate that the 4 citrus fruits (Hallabong, Cheonhyehyang, Cheonggyeon, and Jinjihyang) evidently have antioxidant capacities and their peel parts have the highest antioxidant activities.
