Abstract EN
Sulfated polysaccharides from Ulva lactuca were extracted in hot water and precipitated by ethanol then orally gavaged to rats fed on a hypercholesterolemic diet for 21 days to evaluate the antihypercholesterolemic and antioxidant actions.
Atorvastatine Ca (Lipitor) was used as a reference drug.
The intragastric administration of U.
lactuca extract to hypercholesterolemic rats caused significant decrease of serum total lipids, triglycerides, total cholesterol, LDL-cholesterol and vLDL-cholesterol levels.
Whereas, HDL-cholesterol concentration was markedly increased by 180 %.
Aqueous extract showed a significant ameliorative action on elevated atherogenic index, creatine kinase and lactate dehydrogenase activities of hypercholesterolemic group.
Furthermore, serum activities of transaminases and alkaline phosphatase were also improved.
High fat diet intake caused a highly significantly elevated serum urea, creatinine concentration.
These effects were reversed by oral administration of U.
lactuca extract.
Sulfates polysaccharides extract of U.
lactuca ameliorate hepatic enzymatic (catalase, glutathione peroxidase and superoxide dismutase), nonenzymatic (reduced glutathione & total thiol) antioxidant defenses and thiobarbituric acid reactive substances.
In conclusion, the tested U.
lactuca polysaccharides extract has potent hypocholesterolemic and antioxidant effects in experimentally-induced hypercholesterolemic animal model.
