The present study was carried out to investigate the effects of oral administration of aqueous extract of Punicagranatum seed on Triton X-100 induced hypercholesterolemia in rats. Hypercholesterolemia was induced by single intraperitoneal injection of Triton X-100 and the rats were later treated with aqueous extract of Punicagranatum seed at different dosage levels (50,100 and 200mg/kg body weight) and 10ml/kg/day of standard drug (Astrovastatin) for seven days. Another group received 0.9% Normal saline (1 ml/kg/day). Animals were euthanize by anaesthetization at the end of the experiment to harvest serum used for the biochemical analysis. Aqueous extract of Punicagranatum seed extract prevented triton- induced increase in serum cholesterol, triglyceride (TG), low density lipoprotein (LDL) and decrease in high density lipoprotein (HDL) in a statistically significant manner (p < 0.05) and reversed the elevated serum LDL/HDL ratio comparably to Astrovastatin, The results demonstrated the amelioration of triton- induced hypercholesterolemia in rats by aqueous extract of Punicagranatum seed. Consequently, we can hypothesize that the part of Punicagranatum seed mediated therapeutic effects is associated with its antiatherogenic/hypolidemic component.
