    Abstract:
    Our aim of the study was to evaluate the hypolipidemic activity of leaf juice of Catharanthus roseus (Linn.) G. Donn. in guinea pigs. Adult guinea pigs of either sex were divided into seven groups: group 1 - normal diet; group 2 - high fat diet; group 3 and 4 - normal diet plus leaf juice of Catharanthus roseus (Linn.) G. Donn. in the dose of 0.5 and 1 mL/kg, respectively; group 5 and 6- high fat diet with leaf juice of Catharanthus roseus (Linn.) G. Donn. in the dose of 0.5 and 1 mL/kg, respectively; group 7 - high fat diet plus atorvastatin (3 mg/kg). Above diet treatment was given for six weeks and drug was given during last three weeks. Serum lipid profile (total cholesterol, triglycerides, LDL-c, VLDL-c, HDL-c) was performed in each group of animals before and at the end of six weeks. Histological study of aorta, liver and kidney was done in group 1, 2, 6 and 7 and blood cell count was done in animals that were treated juice of C. roseus (Linn.) G. Donn. before and after juice administration. Simultaneous administration of leaf juice of C. roseus (Linn.) G. Donn. in the dose of 0.5 mL/kg prevents the rise of serum lipid parameters and decreases the fatty changes in the tissue induced by high fat diet, whereas in the dose of 1 mL/kg not only counteracts the elevation, but also significantly (p < 0.05) reduces the serum level LDL-c and the ratio of total cholesterol and HDL-c. Leaf juice of C. roseus (Linn.) G. Donn. possesses significant lipid lowering and anti atherosclerotic activity.
