Ethanol extract of Momordica tuberosa tubers protects liver in paracetamol-induced damage

Abstract

The study assessed the in vivo antioxidant and hepatoprotective activity of an ethanol (70%) extract of Momordica tuberosa Cogn. (Cucurbitaceae) (TMT) tubers in experimentally induced liver damage by paracetamol (2 g/kg, po.) in albino rats. The degree of protection was ascertained by estimating the levels of biochemical markers like SGPT, SGOT, bilirubin (total and direct), ALP, and triglycerides. Tissue GSH and lipid peroxidation were also determined. The ethanol (70%) extract of tubers in an oral administration of 20 and 40 mg/kg doses produced significant protection by decreasing the activity of serum enzymes, bilirubin, cholesterol, triglycerides and tissue lipid peroxidation, while it increased tissue GSH at 40 mg/kg dose. The effects of the extract were comparable to the standard drug silymarin (100 mg/kg). Results suggested that an ethanol (70%) extract of the tubers of the plant at 40 mg/kg possesses potential hepatoprotective activity against paracetamol-induced hepatic damage and significant antioxidant activity in rats.
