Antioxidant and hepatoprotective effects of Crataegus songarica methanol extract.

The protective activity of the methanolic extract of the Crataegus songarica leaves was investigated against CCl4- and paracetamol-induced liver damage. On folklore levels, this plant is popularly used to treat various toxicological diseases. We evaluated both in vitro and ex vivo antioxidant activity of C.

Antihyperlipidemic and Antioxidant Potential of Paeonia emodi Royle against High-Fat Diet Induced Oxidative Stress.

The present study was intended to evaluate the effects of Paeonia emodi rhizome extracts on serum triglycerides (TGs), total cholesterol (TC), low density lipoprotein cholesterol (LDL-c), high density lipoprotein cholesterol (HDL-c), atherogenic index (AI), superoxide dismutase (SOD), and glutathione peroxidase (GPx). The plant was extensively examined for its in vitro antioxidant activity, and the preliminary phytochemical screening was carried out using standard protocols. Male Wistar rats were induced with hyperlipidemia using high-fat diet and were treated orally with hydroalcoholic and aqueous extracts at the dose of 200 mg/kg bw for 30 days.

Hepatoprotective and antioxidant activity of rhizome of Podophyllum hexandrum against carbon tetra chloride induced hepatotoxicity in rats.

Objective: To test possible antioxidant activity of n-hexane extract of Podophyllum hexandrum under in vitro and in vivo conditions.

Methods: The in vitro antioxidant activity was evaluated by the ability of the extract to interact with the stable free radical DPPH, Superoxide (O2-), Hydroxyl (OH-), Hydrogen peroxide (H2O2) radicals, and reducing power ability of the extract was also evaluated. Under in vivo conditions the extract was evaluated for its hepatoprotective activity by measuring different biochemical parameters, such as serum alanine aminotransaminase, serum aspartate aminotransaminase and serum lactate dehydrogenase and antioxidant enzymes.

Radical scavenging and antibacterial activity of Arnebia benthamii methanol extract.

Objective: To evaluate in vitro antioxidant and antibacterial activity of methanolic extract of Arnebia benthamii (A. benthamii) whole plant.

Methods: Plasmid damage was analyzed by agarose gell electrophoresis.

Podophyllum hexandrum aqueous extract as a potential free radical scavenger.

The present study was undertaken to evaluate the effect of the aqueous extract of Podophyllum hexandrum against free radical-mediated damage and also explore its anticancer activity. The extract exhibited significant activity in scavenging 1, 1-diphenyl-2-picryl-hydrazyl radicals, (•)OH radical-mediated DNA damage, and lipid peroxide production in rat liver microsomes. The extract was also tested for its reducing abilities.

Carbon tetrachloride induced kidney and lung tissue damages and antioxidant activities of the aqueous rhizome extract of Podophyllum hexandrum.

Background: The present study was conducted to evaluate the in vitro and in vivo antioxidant properties of aqueous extract of Podophyllum hexandrum. The antioxidant potential of the plant extract under in vitro situations was evaluated by using two separate methods, inhibition of superoxide radical and hydrogen peroxide radical. Carbon tetrachloride (CCl4) is a well known toxicant and exposure to this chemical is known to induce oxidative stress and causes tissue damage by the formation of free radicals.
