  • This study was carried to develop the new material of functional food which antioxidant of natural substances of sprouts. We compared antioxdiative activity and antioxidant substances exist in sprouts. Antioxidaive activities of sprouts were measured by total polyphenolic acid contents, electron donating activity(EDA), SOD-liked activity and hydroxyl radical scavenging ability. Total polyphenolic acid content was very higher in Rape sprouts extract(Rap) than other sprout extracts. Also Rape extract was showed the most excellent antioxdiative activity in SOD liked activity at 86.94%. The EDA was ordered Rape sprouts extract(Rap)>Tatsoi sprouts extract(Tat)>Broccoli sprouts extract(Bro)>Alfalfa sprout extract(Alf). Hydroxy radical scavenging ability was the most effective in Rape sprouts extract(Rap). Therefore we could be certain that Rape sprouts extract(Rap) was the most effective in antioxidative activity from sprouts.

  • Antioxidative activities of ethanol extracts of seed, branch, leaves, and aerial part of Crotalaria sessiflora L. were compared using in vitro experimental model. Solid contents of each extracts were 12.68, 16.28, 13.04, and 18.59 g/ 100 mL, and phenolic acid contents were $0.082{\pm}0.003,\;0.099{\pm}0.010,\;0.071{\pm}0.002,\;and\;0.094{\pm}0.011\;mg/mL$ in branch, aerial part, seed, and leaves, respectively. Extracts prepared from leaves showed highest electron-donating ability toward DPPH. SOD-liked activities were 78.95, 70.85, 74.65, and 87.49% in aerial part, branch, seed, an leaves respectively. Extracts prepared from leaves showed 59.39% inhibitory effect on peroxidation of egg yolk lecithin.
