Abstract: Globally, diabetes is a serious health issue affecting one in 11 adults and consumes 12% of global health expenditure. Prevalence of dyslipidemia in diabetes is not uncommon since decades. Further, patients with type II diabetes have 2-4 folds more risk for cardiovascular disease (CVD). Plants with antioxidant potential are known to have beneficial effects in diabetes and its complications. Natural compounds, flavonoids particularly, ameliorate hyperglycemia as well as CVD. Here, we evaluated common wasteland weed Tephrosia purpurea, used traditionally as folk medicine to treat many disorders including diabetes. We studied the effect of 8-wk treatment of flavonoid-rich fraction of T. purpurea (FFTp) (40 mg/kg/day/p.o.) on various biochemical, cardiovascular and lenticular parameters on streptozotocin (STZ) (45 mg/kg, i.v.) induced type I diabetic rats. STZ administration produced significant hyperglycemia, dyslipidemia, and altered cardiac biomarkers like lactate dehydrogenase, creatinine kinase and reduced antioxidants in lenticular tissues of rats. Treatment with FFTp significantly prevented STZ-induced hyperglycemia, dyslipidemia as well as cardiovascular markers. We observed decreased rate of pressure development (+dp/dt) and decay (-dp/dt) in STZ diabetic hearts which was prevented by FFTp. Further, the soluble protein levels and the antioxidants were also elevated in the diabetic rats by the treatment. In conclusion, our data suggest that FFTp produces beneficial effects on diabetes induced cardiovascular complications and cataract. Such beneficial actions may be attributed to the antioxidant property of flavonoids, quercetin or rutin, present in T. purpurea.
