The antioxidant and hepatoprotective activities of hot aqueous extract from Asparagus albus (A. albus) leaf against CCl4-induced liver damage in rats were investigated. The total phenolic, flavonoid, and condensed tannin contents of hot aqueous extract from A. albus leaf were determined. The antioxidant activity of hot aqueous extract from A. albus leaf was evaluated using the antioxidant capacity, DPPH free radical-scavenging ability and reducing power assays. Different polyphenolic compounds, namely gallic acid, vanillic acid, 3,4 dimethoxybenzoic acid, catechin, rutin, and quercetin were identified. Oral administration of hot aqueous extract from A. albus leaf to male Wistar, intoxicated with CCl4, demonstrated a significant protective effect by lowering the levels of hepatic marker enzymes (aspartate and lactate transaminases) and by improving the histological architecture of the rat liver. The hot aqueous extract from A. albus leaf attenuated oxidative stress by restoring the activities of superoxide dismutase, catalase, and glutathione peroxidase. This study demonstrated that the hot aqueous extract from A. albus leaf protects rat liver from CCl4-induced injury and suggests a potential therapeutic use for A. albus plant.
