Aloe vera Tannin Ameliorates Fructose‐Induced Dyslipidaemia and Oxidative Stress in Wistar Rats
Food Chemistry International, EarlyView.Aloe vera tannin (AVT) significantly enhances liver reduced glutathione and superoxide dismutase activities in rats. Fructose consumption creates dyslipidaemia in rats by significantly increasing serum cholesterol and LDL levels. AVT prevented fructose‐induced dyslipidaemia in rats by controlling the lipid profile. AVT did not affect liver, hippocampus
