Antihyperlipidemic effect of Scoparia dulcis (sweet broomweed) in streptozotocin diabetic rats.
We have investigated Scoparia dulcis, an indigenous plant used in Ayurvedic medicine in India, for its possible antihyperlipidemic effect in rats with streptozotocin-induced experimental diabetes. Oral administration of an aqueous extract of S. dulcis plant (200 mg/kg of body weight) to streptozotocin diabetic rats for 6 weeks resulted in a significant reduction in blood glucose, serum and tissue cholesterol, triglycerides, free fatty acids, phospholipids, 3-hydroxy-3-methylglutaryl (HMG)-CoA reductase activity, and very low-density lipoprotein and low-density lipoprotein cholesterol levels. The decreased serum high-density lipoprotein cholesterol, anti-atherogenic index, and HMG-CoA reductase activity in diabetic rats were also reversed towards normalization after the treatment. Similarly, the administration of S. dulcis plant extract (SPEt) to normal animals resulted in a hypolipidemic effect. The effect was compared with glibenclamide (600 microg/kg of body weight). The results showed that SPEt had antihyperlipidemic action in normal and experimental diabetic rats in addition to its antidiabetic effect.
