A partial least squares regression study with antioxidant flavonoid compounds
(Springer, 2006-06-01)
The quantitative structure-activity relationship of a set of 19 flavonoid compounds presenting antioxidant activity was studied by means of PLS (Partial Least Squares) regression. The optimization of the structures and ...
Structure-antioxidant activity relationships of flavonoids isolated from the resinous exudate of Heliotropium sinuatum
(Pergamon-Elsevier Science Ltd., 2005)
Evaluation of the Antioxidant Activity of the Flavonoids Isolated from Heliotropium Sinuatum Resin Using ORACFL, DPPH and ESR Methodologies
(Sociedad Chilena Química, 2016)
The antioxidant capacity has been determined for a number of flavonoid compounds from Heliotropium sinuatum, a plant that grows in arid areas in the north of Chile. The methodologies used were: ORAC(FL) (oxygen radical ...

Antioxidant flavonol glycosides from Nectandra grandiflora (Lauraceae)
(Editora Unesp, 2002-01-01)
O fracionamento cromatográfico do extrato etanólico das folhas de Nectandra grandiflora resultou no isolamento de dois flavonóides glicosilados que apresentaram atividade antioxidante inibindo a oxidação do beta -caroteno ...

Dimorphandra mollis: Uma Alternativa como Fonte de Flavonóides de Ação Antioxidante
(2010-03-01)
Dimorphandra mollis fruits are rich in fiavonoids rutin and quercetin, which are compounds with high antioxidant activity and can be used to prevent diseases caused by free radicals. The aim of this study was to obtain an ...
Antioxidant activity of flavonols
(2004-04-20)
In this work we use a single new electronic index to describe the antioxidant activity of the flavonols, a special class of flavonoids. We also try to predict theoretically the antioxidant activity of some yet nonisolated ...
