BACKGROUND: Patients with high levels of total cholesterol (TCH), low-density lipoprotein cholesterol (LDL-CH), and triglyceride (TG) are at increased risk of coronary heart disease. Studies have shown that flavonoids and antioxidant compounds have beneficial effects on hyperlipidemia.
OBJECTIVES: The aim of the present study was to evaluate the effects of extract of Hypericum perforatum (EHP) on the serum lipid profile (TCH, TG, and LDL-CH), aminotransferase, alkaline phosphatase, and lipid peroxidation in hyperlipidemic rats.
MATERIALS AND METHODS: Thirty-two male rats weighting 200± 10 g were randomly divided into four experimental groups: 1) control, 2) control + EHP, 3) hyperlipidemia, and 4) hyperlipidemia + EHP. The rats in the hyperlipidemic groups were fed a high-fat diet for 60 days, and EHP (300 mg/kg) was injected intraperitoneally for 2 weeks in the rats in the second and fourth groups. At the end of the experimental period, blood samples from each group were analyzed.
RESULTS: There was a significant reduction in LDL-CH in the control + EHP group and the hyperlipidemia + EHP group (P<0.05). TCH was significantly reduced in the control + EHP group (P<0.05). There were no significant changes in the levels of TG and HDL-CH. Malondialdehyde, aspartate aminotransferase, and alanine aminotransferase were significantly reduced in the hyperlipidemia + EHP group (P<0.05), with no significant change in alkaline phosphatase.
CONCLUSIONS: EHP was able to both reduce LDL-CH and to significantly decrease markers of oxidative stress and lipid peroxidation induced by hyperlipidemia. Therefore, this herb, as a new pharmacological component, could be used to reduce certain blood lipids, lipid peroxidation, and aminotransferase markers.
