Objectives: to evaluate the lipid lowering effect on the blood lipid profiles of three standardized natural extracts on rat. In the study were took male Wistar rats, weighting 200±10 g, using a hyperlipidemic model using Triton WR, 10 mg/kg b.w., intraperitonealy. After 20 hours the rats were treated with 1 mL suspension of standardized extracts of Alii sativi bulbus, Hippophae fructu, Squalus achantios, 1 ml/100 g b.w., orally. The controls received NaCl 0,9%, 10 ml/kg b.w. orally. After two hours blood samples were took and we determined the total lipid profile, blood cholesterol, HDL-c, LDL-c, plasma triglycerides. The statistical evaluation of the results was made by the “t” student test. According to the blood test results the total blood lipids increased with 23,75% after the treatment with Triton WR, 10 mg/kg b.w., intraperitoneally. After the administration of the natural standardized extracts the total lipid profile decreased with values between 2,13% and 17,32%. The total cholesterol profile increased on the hyperlipidemic model with 21,90% and decreased after the treatment with 33,58% for the combination of the natural extracts containing Alii sativi bulbus, Hippophae fructu, Squalus achantios  and the LDL cholesterol decreased with 51,18% compared with untreated control Triton batch.

Conclusions: the combination of the standardized extracts of Alii sativi bulbus, Hippophae fructus, Squalus achantios has lipid lowering properties, reducing the total triglycerides, cholesterol, LDL-cholesterol and increases the HDL cholesterol levels.
