Antioxidant activity of lactic acid bacteria is associated with multiple health-protective effects. Traditional indexes of chemical antioxidant activities poorly reflect the antioxidant effects of these bacteria in vivo. Cellular antioxidant activity (CAA) assay was used in this study to determine the antioxidant activity of cell-free supernatants (CFSs) of 10 Lactobacillus strains. The perform...
BACKGROUND Lampaya medicinalis Phil. (Verbenaceae) is a plant used by Aymara and Quechua ethnic groups from Northern Chile as folk medicine in the treatment and cure of various diseases. The aim of this study was to investigate the in vitro antioxidant activity, total phenols content, total flavonoids content, total antioxidant activity, reducing power, brine shrimp cytotoxicity and identify th...
Composition, antioxidant capacities and cell inhibition properties of curcuminfree turmeric (Curcuma longa L.) oils from different sources were evaluated by chromatographic method, two different in vitro antioxidative activity assays (DPPH* free radical scavenging assay and reducing power assay) and two different cancer cell lines (Caco-2 and MCF-7). Turmeric oil A (TOA) contains zingiberene, t...
BACKGROUND Rhododendron anthopogonoides Maxim, a kind of traditional Tibetan medicine, has been used to remove body heat, body detoxification, cough, asthma, stomachic and swelling, eliminate abundant phlegm and inflammatory for a long time. In the present study, the total phenols and total flavonoid contents as well as antioxidative properties of the crude extract and solvent fractions of R. a...
The present work is carried out to study the antioxidant potential of ethanolic extract of Alstonia scholaris Linn. ( Apocynaceae ) using various in vitro tests including 1,1-diphenyl-2-picryl-hydrazil (DPPH . ) free radical scavenging, metal ion chelating, hydrogen peroxide scavenging, superoxide anion radical scavenging, and ferric thiocyanate reducing ability. Ethanolic ex...
Oxidative stress resulted from free radicals and reactive oxygen species (ROS) are associated with many diseases. Phytotherapy has known a great evolution all the world some medicinal plants important remedies of Myrtle (Mrytus communis L.) is plant Myrtaceae family which common in Mediterranean region, flowering, always green leaves fruit. This study aims to investigate vitro antioxidant capac...
Amalakayas Rasayana (AR) is a polyherbal formulation mentioned in Ayurveda to treat aging and age-associated diseases. Being an antiaging drug, AR may have antioxidants and free radical scavenging activity to minimize free radical-induced damage which is a key cause of aging. The methanolic extract of AR was evaluated in vitro for total phenolic and tannin content, free radical scavenging activ...
the present study was carried out to determine the free radical scavenging properties of some plants, found in malaysia. the air-dried leaves of each plant (20 g) were soaked in distilled water (1:20; w/v) for 72 h at room temperature. collected supernatants were tested for free radical scavenging activity against the dpph and superoxide anion radical scavenging assays. all extracts were found ...
Abstract When glucose and Amadori products are auto-oxidized, glycation occurs, resulting in the formation of early (Amadori) late advanced end (AGEs), as well free radicals. Glycation an increase radical activity induce diabetic complications. Antioxidant antiglycation compounds may aid prevention oxidation glycation. The goal this study was to assess antioxidant capacity C-phycocyanin (C-PC) ...
The present study was conducted to evaluate the antioxidant properties of wheat and rice flours under simulated gastrointestinal pH condition. After subjecting the wheat and rice flour slurries to simulated gastrointestinal pH condition, both slurries were centrifuged to obtain the crude phenolic extracts for further analyses. Extraction yield, total contents of phenolic and flavonoids were det...
