Abstract

BACKGROUND:

The present study was designed to investigate the hypolipidaemic and hypoglycaemic effects of total flavonoids from seed residues of Hippophae rhamnoides L. (FSH) in a high-fat diet fed mouse model. Consumption of a high-fat diet (HFD) for 4 weeks caused a significant rise of serum total cholesterol in mice. These hypercholesterolaemic mice then were orally administrated with different doses of FSH (50, 100 and 150 mg kg⁻¹ body weight) and simvastatin (20 mg kg⁻¹ body weight) for another 12 weeks under continuous HFD feeding.

RESULTS:

FSH administration markedly reduced total mouse body, liver, and epididymal fat pad weights. Serum total cholesterol and low density of lipoprotein-cholesterol levels were also significantly decreased by FSH treatment. Additionally, FSH significantly lowered total cholesterol and triglyceride concentrations in liver, and the results were corroborated by transmission electron microscope findings. The rise in serum glucose was significantly suppressed by FSH treatment while improving impaired glucose tolerance.

CONCLUSION:

These results suggest that FSH possesses hypolipidaemic and hypoglycaemic properties in mice fed a high-fat diet and could be developed as a supplement in healthcare foods and drugs.
