In this study, in vitro antimicrobial and antioxidant activity of Plagiomnium medium (Bruch & Schimp.), Leptodon smithii (Hedw.), Platyhypnidium alopecuroides (Brid.), Pterogonium gracile Pylasia polyantha (Hedw.) Timmia bavarica (Hessl.) was investigated. The prepared moss ethanol extracts determined using the disk diffusion method against 20 strains. DPPH (2,2-difenil-1-pikrilhidrazil) us...

The aim of this study was to determine the in vitro antioxidant activity, free radical scavenging property and the beneficial effects of extracts of various parts of Syzygium guineense in reducing oxidative stress damage in the liver. The effects of extracts on free radicals were determined on radicals DPPH, ABTS, NO and OH followed by the antioxidant properties using Ferric Reducing Antioxidan...

The phytochemical, antimicrobial activity against gram negative and positive bacteria and fungi, DPPH radical scavenging and FRAP assay antioxidant activities of aqueous and organic crude extracts of Millingtonia hortensis, Andrographis paniculata, Aegle marmelos, Coccinia grandis, Tinospora cordifolia, Achyranthus aspera was studied invitro. The phytochemical screening of crude plant extracts ...

BACKGROUND Antioxidant, antiproliferative and apoptosis inducing activities of a natural polyphenolic compound, ellagic acid, were studied. MATERIALS AND METHODS DPPH radical scavenging and lipid peroxidation inhibitory activities were observed. Activities of antioxidant enzymes, superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX) were measured in ellagic acid-treated ...

Objective: The aim of the present investigation was to evaluate the phytochemical constituents, free radical scavenging activities and antioxidant properties of the methanol extract of leaves of Artocarpus heterophyllus. Methods: The phytochemicals in the methanol extract of leaves of A. heterophyllus were determined qualitatively and quantitatively using standard methods. The antioxidant activ...

Oxidative damage has been suggested to play a role in the pathogenesis of basal cell carcinoma (BCC). This study illustrated an involvement of oxidative DNA damage and changes in antioxidant defenses in BCC by conducting a case-control study (24 controls and 24 BCC patients) and assessing urinary 7,8-dihydro-8-oxo-2'-deoxyguanosine (8-oxo-dGuo), plasma antioxidant defenses including catalase (C...

The effects of aging and food restriction on the activities and mRNA levels of antioxidant enzymes in rat livers were examined. Rats were fed ad libitum every day (AL) or ad libitum on every other weekday (FR). At 30 months of age, the catalase and glutathione peroxidase activities were lower, whereas the thiobarbituric acid (TBA) value, an index of lipid peroxidation of the AL rats, was higher...
