Associations of flavonoids and natural dyes in the control of lipidic metabolism.

Abstract

The present work evaluates the effects of rutin and naringenin, isolated and in association with anthocyanin and monascus, on lipidic metabolism of rats. These compounds were dissolved in propylene glycol and administered by intraperitoneal route in two doses of 5mg/kg of body weight. The first dose was administered together witli the Triton, compouiid responsible for induction of hyperlipidaemia, and the second, twenty hours later. After fourty three hours of the first dose aiid Triton administration, the blood was retreat and cliolesterol, HDL-cholesterol, and triacylglycerols were dosed. Results evidence the largest percentual reduction of cholesterol for naringenin + monascus, naringenin + anthocyanin, rutin + monascus and rutin + anthocyanin . On the other hand, for HDL-cholesterol, the best results were obtained with naringenin alone. Finally, the best reduction of triacylglycerols levels was showed for naringenin, naringenin + monascus and rutin + anthocyanin associations.
