| Abstract;Peptides having strong superoxide scavenging activities were separated from a soybean protein digest by chromatographic methods such as ion-exchange and gel-filtration. The most potent fraction (SP-1) obtained by SP-Sephadex C-25 chromatography was further separated into peptide components using ODS HPLC. The amino acid sequences of these peptides were: Ala-Val-Pro-Tyr-Asn-Leu (AVPYNL) and Leu-Val-Pro-Pro-Gln-Glu-Glu-Gln-Lys (LVPPQEEQK). The IC50 values of AVPYNL and LVPPQEEQK for superoxide scavenging activity were 126.MU.M and 186.MU.M, respectively, determined by the tetrazolium salt XTT method. The IC50 values of AVPYNL and LVPPQEEQK for hydroxyl radical scavenging activity were 6.1.MU.M and 9.2.MU.M, respectivity. (author abst.) |
