Key Points

Rutin improved dioxin excretion, enhancing urine output by 30% and fecal excretion by 25%.
Control exposure involved a dioxin mixture administered at 10 µg/kg, showing significant results after treatment.
Oral administration of rutin was conducted over 30 days, revealing its modulatory role in toxicant elimination.
Potential implications include natural detoxification methods for reducing environmental toxicant exposure.

Abstract

Dioxins are persistent organic pollutants with long biological half-lives and a high tendency for bioaccumulation, posing serious toxicological risks to humans and wildlife. This study investigates the modulatory role of rutin, a naturally occurring flavonoid, in promoting the excretion and reducing the systemic retention of polychlorinated dibenzo-p-dioxins and dibenzofurans in vivo. Wistar rats were exposed to a controlled dioxin mixture (10 µg/kg body weight) and administered rutin orally (0.02 g/kg) for 30 consecutive days. Biological samples including feces, urine, and serum were collected and analyzed via high-resolution gas chromatography coupled with high-resolution mass spectrometry (HRGC/HRMS). Rutin significantly enhanced the excretion of octachlorodibenzo-p-dioxin (OCDD) by 30% in urine and 25% in feces, while reducing lipid-adjusted serum dioxin levels. Additionally, biochemical and hematological markers showed improved hepatic and renal function in the rutin-treated group. These findings suggest that rutin may facilitate dioxin detoxification through enhanced metabolic clearance and reduced tissue retention. The study contributes to understanding natural detoxification mechanisms and supports future research into bioactive compounds for mitigating environmental toxicant exposure.
