WebDec 18, 2024 · Based on our success with a computational approach, in this study, the methylperoxyl radical scavenging activity of 12 natural stilbenes was evaluated based on kinetic and thermodynamic calculations. The results suggest that for stilbenes hydrogen atom transfer (HAT) is a main mechanism for the ROO˙ radical scavenging in the gas. Webz' radical scavenging by the carotene lycopene, and the xanthophylls lutein, zeax-anthin, astaxanthin, and canthaxanthin have been investigated by pulse radiolysis. The mechanism(s) and rates of scavenging are mainly dependent on the nature of the oxidising radical species but much less dependent on the carotenoid structure. 2. Materials and ...
