| Abstract | Sylvatesmin (SYL) and lantbeside (LAN) are two lignans, isolated from a Chinese folk medicinal herb, Lancea tibetica. Their abilities of scavenging oxidizing free radical models, (OH)-O-., SO4.- and N-3(.), were investigated in aqueous solution by pulse radiolysis techniques. The OH-adduct radicals with small amount of oxidized products were formed by the reaction of SYL or LAN with (OH)-O-. radical. SYL undergoes one-electron oxidation either by SO4.- or N-3(.) radicals, LAN can only be detected to react with stronger oxidant SO4.- radical anion. No reaction between LAN and N-3(.) radical was detectable. The relationship of structure with the abilities of scavenging free radicals was discussed. The reaction rate constants were determined by analysis of the build-up trace of the radical products. (C) 2003 Elsevier Ltd. All rights reserved. |
