1.  Investigations Regarding the Antioxidant Character of Some Flavonols

Authors: R. Pop, M. Medeleanu and M. Andoni


Abstract:

The antioxidant character of three flavonols (azaleatin, kaempferide and isorhamnetin) has been evaluated at HF/6-31+G level of theory. Thermodynamic parameters like BDE (bond dissociation enthalpy) have been computed, as well as frontier charge density indices. Based on these results, a hierarchy of the antioxidant capacity of OH groups within the three investigated flavonols has been proposed. Also, the atomic charges were computed by using three different approaches.


Keywords: flavonols, atomic charge, bond dissociation enthalpy, ab initio
