Dietary Phenolic Acids of Macrotyloma uniflorum (Horse Gram) Protect the Rat Heart Against Isoproterenol-Induced Myocardial Infarction.

The present study investigates the cardioprotective activity of the Macrotyloma uniflorum seed extract (MUSE) and its phenolic acids (p-coumaric acid and ferulic acid) in isoproterenol (ISO)-induced myocardial infarction in rats. The previously mentioned phenolic acids were isolated and quantified from MUSE by HPLC. Pretreatment of gemfibrozil (reference standard), MUSE (250 and 500 mg/kg) and the phenolic acids for 30 days to rats treated with ISO (85 mg/kg) on the last 2 days resulted in a significant attenuation of the ISO-elevated levels of serum marker enzymes (aspartate aminotransferase, lactate dehydrogenase and creatine phosphokinase MB), total cholesterol, triglycerides, uric acid, C-reactive protein and malondialdehyde and a restoration of the levels of the ISO-depleted marker enzymes, reduced glutathione and the antioxidant enzymes-superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase in heart.

Antioxidant and hepatoprotective effect of Garcinia indica fruit rind in ethanol-induced hepatic damage in rodents.

The protective effects of aqueous extracts of the fruit rind of Garcinia indica (GIE) on ethanol-induced hepatotoxicity and the probable mechanisms involved in this protection were investigated in rats. Liver damage was induced in rats by administering ethanol (5 g/kg, 20% w/v p.o.
