Abstract
OBJECTIVE
To study the effects of Cydonia oblonga Miller (COM) total flavonoids (TF) from leaves and fruit on the blood lipid and antioxidant potentials using hyperlipidaemic rat models.
METHODS
Hyperlipidaemic rat models were created with high-lipid emulsion. Rats were distributed into normal controls, hyperlipidaemic models, and daily high (160mg/kg), medium (80mg/kg) and low (40mg/kg) TF from leaves and fruit and simvastatin (5mg/kg) groups. After four weeks, serum total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), alanine aminotransferase (ALT), aspartate aminotransferase (AST), as well as hepatic superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and malondialdehyde (MDA) were measured.
RESULTS
Compared with the hyperlipidaemic model group, TF significantly reduced serum TC, TG, LDL-C (P<0.01), ALT and AST (P<0.01 or P<0.05) and increased HDL-C (P<0.05 or P<0.01). TF also reduced MDA (P<0.01 or P<0.01).
CONCLUSION
COM total flavonoids can effectively regulate the metabolism of lipids, and remove oxygen free radicals. This confirms its potential value in the prevention and treatment of hyperlipidaemia.
