By the data shown in the table 6 as can be seen, compare with the normal control group, high fat control animals serum and liver L PO content obviously raise (P<0.05 or P<0.01), and active obviously reduce (P<0.05 or P<0.01) of SOD shows that hyperlipidemia rats is with the free radical lipid peroxidation injury.With high fat matched group relatively, the oral big or middle dosage multiplieronion extract of animal (50,100mg/kg) can make hyperlipidemia rats serum and liver L PO content obviously reduce (P<0.05 or P<0.01), SOD activity then obviously raise (P<0.05).

By the data shown in the table 7 as can be seen, the normal control group relatively, the whole blood of high fat control animals is low to be cut, in cut and height is cut viscosity and all obviously increased (P<0.05), show that hyperlipidemia rats is with hemorheological change.Compare with high fat matched group, heavy dose of multiplieronion extract (100mg/kg) can obviously reduce whole blood lowly cut, in cut and height is cut viscosity (P<0.05 or P<0.01), in dosage multiplieronion extract (50mg/kg) can reduce obviously that whole blood is low to be cut and height is cut viscosity (P<0.05), and low dose of multiplieronion extract (25mg/kg) only can reduce the whole blood height and cuts viscosity (P<0.05).

At last, inventor's using-system method has been observed the influence of multiplieronion extract to hyperlipidemia rats hepatic tissue lipidosis.
Respectively organize the fixing section of liver specimens back row fat stains, observe hepatic tissue lipidosis situation.The result as seen, the hepatocyte of 10 animals of normal control group there is no steatosis (0/10); The all visible steatosis (10/10) of the hepatocyte of 10 animals of high fat matched group, and the hepatic cell fattydegeneration of taking each treated animal of big, the little multiplieronion extract of neutralization and taking the lovastatin treated animal is respectively 6/10,4/10,3/10,4/10, and fat vacuole obviously reduces.Through X
2Check, three dosage groups of multiplieronion extract and lovastatin group and high fat matched group comparing difference be (p<0.05 or p<0.01) significantly, shows that the multiplieronion extract can obviously suppress the deposition of hyperlipidemia rats liver fat.
