AbstractThe photo-physical and photo-chemical properties of melatonin (ML) were studied by 266 nm laser flash photolysis (LFP). ML undergoes photo-ionization to produce radical cation of ML (ML center dot+) and hydrated electrons (e(aq)(-)), while excited triplet state (ML)-M-3* is also formed during photolysis. The oxidation via one electron transfer from ML to SO4 center dot- and the triplet state of riboflavin ((RF)-R-3*) has been also investigated and the rate constants for the process have been determined to be 8.0 x 10(9) and 1.4 x 10(9) L.mol(-1).s(-1) respectively. The radical cation of 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid)(ABTS(center dot+)) scavenging capacities of melatonin and other antioxidants are compared in this paper.
