ABSTRACT
This study was designed to address the synergistic effect of tincture of Crataegus (TCR) and Mangifera indica L. (MNG) extracts on the lipid and antioxidant parameters in the development of aortic lesions in diet-induced atherosclerosis in rats. TCR, is an alcoholic extract made from the berries of Hawthorn, Crataegus oxyacantha with flavanoids as the main constituent. MNG, is an alcoholic extract made from the stem bark of Mangifera indica L. with polyphenols as the main constituent. Simultaneous oral administration of these two extracts (0.5 ml/100 g body weight) to rats fed with an atherogenic (4% cholesterol, 1% cholic acid, 0.5% thiouracil) diet prevented the elevation of lipids in the serum and heart and also caused a significant decrease in lipid accumulation in the liver and aorta reverting the hyperlipidaemic condition of these rats. These extracts significantly restored the activity of antioxidant enzymes such as superoxide dismutase, catalase, glutathione peroxidase, and glutathione, thereby restoring the antioxidant status of the organism to almost normal levels. This effect could be attributed to the synergistic activity of flavonoids in TCR and polyphenols of MNG.
