Abstract
The objectives of this paper were to evaluate the antioxidant activity of lycopene towards the trichloromethyl peroxyl radical (CCl 3O 2 ) and to obtain a precise rate constant using a pulse radiolysis technique. Lycopene was extracted and purified from tomato paste and its purity reached 95.0% (HPLC analysis). CCl 3O 2 was generated from a pulsed aqueous air-saturated solution of 2-propanol (2 M), acetone (1 M) and CCl 4 (10 −2 M). The observed spectrum showed an intense bleaching of the lycopene ground-state absorption in the region 350–450 nm and the bleaching rate constant was determined to be 1.17×10 9 M −1s −1, which indicated a rapid interaction between lycopene and CCl 3O 2 .
