- Studies of the Antioxidative Activities of Humic Substances in Peat (1)
抄録
<p>Humic acid (HA) and fulvic acid (FA) were prepared from peat and they had high total polyphenol contents (HA: 421 mg/g and FA: 299 mg/g). Antioxidative activity assays were carried out as following; (1) scavenging activities for 1,1-Diphenyl-2- picrylhydrazyl (DPPH) radical, (2) inhibitory effect on oxidation of linoleic acid, (3) inhibitory effect on 2,2’-azobis (2-amidinopropane) dihydrochloride (AAPH)-induced hemolysis of rabbit erythrocytes in vitro, and (4) effect on Cu2+-mediated conjugated dienes formation in human low density lipoprotein (LDL). Both of HA and FA showed relative activities against (1)-(3). That is, (1) HA and FA showed about 90 % of scavenging activities for DPPH radical at the concentration of 250 μg/ml, (2) at the concentration of 81 μg/ml, HA and FA showed inhibitory effect on oxidation of linoleic acid 57 % and 27 %, respectively, (3) HA as well as ascorbic acid (AA) showed about 90 % of inhibitory effect on AAPH-induced hemolysis of rabbit erythrocytes (at the concentration of 67 μg/ml), and (4) HA inhibited Cu2+-mediated conjugated dienes formation in human LDL with the dose dependently. The inhibition mechanism by HA was suggested to be different from that of AA.</p>
