Arnebia euchroma is from Boraginaceae family. Various therapeutic effects have been reported for different species of this plant. The aim of this study was to investigate antioxidant activity of hydroalcoholic extract of the root of A. euchroma and its protective effect on hepatotoxicity induced by CCl4 in mice. In this experimental study, A. euchroma was extracted with ethanol solvent by macer...

The stem bark of Enantia chlorantha is commonly used for the treatment of malaria and other ailments of the human body such as cough and wound. The plant had been intensely studied for its antimicrobial activities and antipyretic properties. However, the efficacy and mechanisms of action of the plant remain unclear. Therefore, the objective of the present study was to determine the in vitro ant...

Background and objectives: Marrubium parviflorum Fisch. & C.A.Mey. (Lamiaceae) is a medicinal plant with documented antioxidant and analgesic effects distributed in Iran and Turkey. In the present study, the aerial parts of this species were subjected to phytochemical analysis, as well as antioxidant activity assays. Methods: Antioxidant activity of th...

BACKGROUND Plants are the natural source of antioxidants as well as antimicrobial compounds that has great potentials in pharmaceutical industry. In the present study, two medicinal plants Atropa belladonna and Matricaria chamomilla were collected from Northern areas of Pakistan. MATERIALS AND METHODS The extracts of the collected plants were obtained by microwave assisted extraction (MAE) wi...

Free radicals react with biological molecules and destroy the structure of cells, which eventually causes free-radical induced disease such as cancer, renal failure, aging, etc. In this study, 6 extracts and 4 pure compounds of Terminalia chebula RETZ. were investigated for anti-lipid peroxidation, anti-superoxide radical formation and free radical scavenging activities. The superoxide radical ...

The antioxidant activity of defatted ethanolic extract of the leaves of Blumea mollis were studied for its free radical scavenging property on different in vitro antioxidant models like DPPH radical, hydroxyl radical, nitric oxide radical scavenging activity, reducing power, superoxide anion radical scavenging activity were analyzed. The extract showed free radical scavenging property in dose-d...

Background & Aim: Free radicals play a crucial role in the development of tissue damage in various human diseases such as cancer, aging, neurodegenerative disease, malaria and arteriosclerosis, and pathological events in living organisms. Antioxidants may have an important role in the prevention of these diseases. The aim of this study is to evaluate potency of scavenging of DPPH free radicals ...

Quercetin is a typical flavonoid with diverse biological effects, attributable to its free radical scavenging activity. Bioavailability of quercetin aglycone and its glycosides is an important factor for its antioxidant activity in vivo. A severe limitation exists and is imputable to very poor absorption of quercetin when administered orally. To overcome this limitation, development of a value ...
