Conformational analysis of delphinidin, pelargonidin and malvin was performed.
class="glyphImg imgLazyJSB">OH and class="glyphImg imgLazyJSB">NO antiradical activity was examined theoretically and experimentally.
EPR measurements proved Dp, Pg and Mv was selective towards hydroxyl radical.
EPR measurements proved Dp, Pg and Mv was not selective towards nitric oxide.
Molecules investigated reacted with hydroxyl radical via HAT and SPLET mechanisms.
