英文摘要	The interactions of carotenoids (bixin, P-carotene and lycopene) with CCl3OO. in aqueous and i-propylalcohol solution saturated with air have been studied by pulse radiolysis. For bixin and beta-carotene reaction products from forming process, absorbing in the region of 650 nm, is observed with concomitant carotenoid bleaching (bixin at 500 nm, beta-carotene at 450 nm). Their rate constants from forming process are 1.78 X 10(8) and 7.8 X 10(7) mol(-1) . L . s(-1) respectively. However, in the case of lycopene, no such a forming process of reaction as bixin and beta-carotene can be observed although there is the bleaching reaction (rate constant 4 X 107 mol(-1) . L . s(-1)). The results suggest that the carotenoid radical cation and an additional radical are produced in the case of bixin and-p-carotene, whereas lycopene undergoes electron transfer with CCl3OO., forming cation radical.
