Antioxidants have reactive oxygen species (ROS) scavenging ability with great relevance in the prevention of oxidative stress. The present study aimed to examine the antioxidant and ROS scavenging activities of 70% methanolic extract of Tinospora cordifolia. The plant was found a significant source of carbohydrate, alkaloid, ascorbic acid, tannin, phenolic and flavonoid compound. The extract wa...

It is well known that the intake of antioxidants with increased consumption of fruits and vegetables and medicinal herbs contributes towards reduced risk of certain diseases including cancers. This study aims to evaluate the broad-spectrum antioxidant and antimutagenic activities as well as to elucidate phytochemical profile of an Indian medicinal plant Murraya koenigii (curry) leaves. Leaves o...

The essential oil compound, fatty acid composition and the in vitro antioxidant activity of the root and aerial of Glycyrrhiza echinata L., a medicinal plant growing in Turkey, have been studied. The antioxidant capacity tests were designed to evaluate the antioxidant activities of methanol extracts. Total phenolic and flavonoid concentrations of each extract were also determined by using both ...

The well known medicinal plant, Cichorium intybus L. (Asteraceae) contains dietary oligofructose compounds which have beneficial effect on carbohydrate and lipid metabolism, other compounds e.g. polyphenol type derivatives could be responsible for the antioxidant properties reported in several studies before. Male Fischer rats were kept on normal and lipid rich diet supplemented with chicory ex...

The 2,2'-diphenyl-1-picrylhydrazyl (DPPH(•)) method is commonly applied for the estimation of antioxidant activity of single compounds and plant extracts. In this method, the amount of disappeared DPPH(•) in the examined system, determined spectrophotometrically, is a measure of the antioxidative (hydrogen-donating) activity of compounds. The present paper discusses the influence of buffer comp...

objective(s) the objective of this study was to determine the effect of aqueous extract of origanum vulgare l. ssp. viridis (org) on discrimination learning and long term potentiation (ltp) in ca1 region of the rat hippocampus. materials and methods a group of adult male wistar rats weighing 275±25 g received aqueous extract of org (150, 300, 450 mg/kg/day) by intraperitoneal injection for one ...

BACKGROUND Phyllanthus debilis (Elapitawakka) is a medicinal plant used in traditional systems of medicine in Sri Lanka. Present study was carried out to evaluate in-vitro anti-oxidant and anti-proliferative activity of the water extracts of aerial parts (AP) and roots (RP) of P.debilis plant and the role of polyphenolic compounds in view of its medicinal use. METHOD Total polyphenols, flavon...

BACKGROUND Albizia adianthifolia is used traditionally in Cameroon to treat several ailments, including infectious and associated diseases. This work was therefore designed to investigate the antioxidant and antimicrobial activities of ethyl acetate extract, fractions and compounds isolated from the stem bark of this plant. METHODS The plant extract was prepared by maceration in ethyl acetate...
