Abstract

Abstract Radiolysis of rutin was performed in aerated ethanolic solution. Two major radiolytic products (RP1, RP2) were isolated by HPLC, and their possible structures were deduced from their UV, IR and MS spectra, and elementary analysis as well. The G -values of RP1 and RP2 increase with increasing rutin concentration, and in all cases both of them equal the G -value of rutin consumption. The addition of rutin leads to the decrease of G (H 2 O 2 ) but has little effect on G (CH 3 CHO). Therefore the formation of RP1 and RP2 was proposed to be from further addition of HO%s 2 to the phenolic radical (generated from H-abstraction by HO%s 2 ) followed by fragmentation.
