Pharmacological Screening of Trachyspermum ammi for Antihyperlipidemic Activity in Triton X-100 Induced Hyperlipidemia Rat Model

BACKGROUND: Mortality rate is increasing due to cardiovascular problems throughout the world. These cardiac problems are directly associated with dyslipidemia. AIM: The aim of this study was to evaluate the antihyperlipidemic effect of aqueous extract and methanol extract of Trachyspermum ammi at 1 g/kg, 3 g/kg, and 5 g/kg dose levels in rats. MATERIALS AND METHODS: For this purpose, 45 male albino rats were used and randomly divided into nine equal groups (n = 5). The lipid levels were increased after 24 h of single intraperitoneal injection of Triton X-100 (100 mg/kg) in rats. Aqueous and methanol extracts equivalent to 1 g/kg, 3 g/kg, and 5 g/kg were administered orally to the rats for 21 days. Atorvastatin (10 mg/kg) was used as standard drug. Blood samples were collected at 0, 2(nd), 9(th), 16(th), and 23(rd) day by a direct cardiac puncture in Vacuette(®) heparin tubes. Serum was separated and then analyzed for lipid profile, liver function test (LFT), and renal function test (RFT) using standard diagnostic kits. RESULTS: Results showed that extracts at 3 g/kg and 5 g/kg decreased the levels of total cholesterol, triglyceride, and low-density lipoprotein and increased high-density lipoprotein concentration in serum. T. ammi also decreased LFT and RFT parameters at the end of the study. CONCLUSION: T. ammi possessed antioxidant and antihyperlipidemic activities along with hepato- and nephro-protective effects. SUMMARY: Aqueous and methanol extracts of T. ammi were administered orally at 1-, 3-, and 5 g/kg doses to hyperlipidemic rats (Triton X-100 induced hyperlipidemia) and atorvastatin (10 mg/kg, orally) was used as standard drug. Methanol extract at 5 g/kg showed antihyperlipidemic effect that is identical to that of standard drug.
