The Influence of Ascorbic Acid on Free Radical Scavenging Activity of Selected flavonoids
Języki publikacji
Abstrakty
Flawonoidy obejmują liczną grupę związków fenolowych występujących w wielu roślinach i produktach roślinnych, między innymi w owocach, warzywach, kaszy gryczanej, roślinach strączkowych, herbacie, czekoladzie, czerwonym winie, przyprawach i ziołach. Stanowią zatem istotny i nieodłączny składnik naszej diety. Związki polifenolowe pochodzące z surowców roślinnych wchodzą również w skład wielu preparatów farmaceutycznych i suplementów diety. Wiele wyników badań naukowych wskazuje na odwrotny związek pomiędzy spożyciem żywności bogatej w związki polifenolowe, zwłaszcza flawonoidy, a obniżeniem zachorowalności na choroby dietozależne, głównie układu krwionośnego i choroby nowotworowe. (fragment tekstu)
Many scientific data indicate an inverse correlation between consumption of food rich in polyphenols, especially flavonoids, and incidence of diseases related to the diet, especially cardiovascular disease and cancer. These protective effects have been attributed, in large part, to the antioxidant activity of these compounds. Quercetin and rutin are flavonoids ubiquitously present in many plant materials. They are also present in many pharmaceutical preparations and diet supplements in combination with ascorbic acid and/or with other compounds. The present study is focused on interactions between ascorbic acid and quercetin or rutin, influencing their free radical scavenging activity measured using the TEAC and DPPH assays.
