Ameliorating efficacy of eugenol against metanil yellow induced toxicity in albino Wistar rats.

Metanil yellow, an azo dye, is a non-permitted synthetic food colour used extensively in India and other developing countries as food additive. Present communication reports the toxic effects of metanil yellow on hepatic and kidney tissues and its amelioration by eugenol, vitamin E and vitamin C. Oral administration of metanil yellow in albino Wistar rats for 28 days caused elevation in serum enzymes (glutamate oxaloacetate transaminase, gluatamate pyruvate transaminase, alkaline phosphatase), and total bilirubin along with decline in albumin and total protein levels.

Renoprotective effect of cinnamaldehyde in food color induced toxicity.

Present study reports the effects of metanil yellow, a non-permitted food colouring dye, on the biomarkers of oxidative stress and kidney function in blood and renal tissue of albino Wistar rats and its mitigation by cinnamaldehyde, a major phytoconstituents of cinnamon. Oral administration of metanil yellow in rats caused about 70% reduction in ferric reducing ability (FRAP 5.1 μM/L) and 50% decline in reduced glutathione (GSH 59.
