BACKGROUND Production of reactive oxygen species is a common cause in alcohol induced liver diseases. Decoction prepared from the whole plant of Eriocaulon quinquingulare is prescribed to treat liver disorders. The aim of this study was to investigate the hepatoprotective activity and antioxidant capacity of the water extract of E. quinquangulare in vitro. METHOD The aqueous extract of the wh...

To uncover the antioxidant and free radical scavenging activity, five different extracts of Terminalia arjuna bark were examined. In the present study, the free radical scavenging potential of five extracts of the bark of Terminalia arjuna was assessed by measuring its capability for scavenging 2, 2-diphenyl-1picrylhydrazyl (DPPH) radical, hydrogen peroxide radical, nitric oxide radicals (NO), ...

Recent studies have suggested that Mentha longifolia L. extracts (ME) have anti-inflammatory and antioxidant activities. In this paper, we attempted to determine the effect of ME in a rat stroke model. Five groups of experimental animals were used (n=14); the first and second groups (control and sham, respectively) received intraperitoneal injections of daily-distilled water; the other three gr...

The study aimed to identify the phenolic compounds present in Centella asiatica (L.) (C. asiatica) extract and evaluate the respective antioxidant potential as well as its cholesterol-lowering effects in the experimental animal model. Herein, the antioxidant potential of extracts was assessed by its free radical scavenging activity such as 2, 2-diphenyl -1- picrylhydrazyl as well as reducing ca...

The objective of the study was to investigate the in vitro antioxidation activity of lycium barbarum polysaccharides (LBP). Ultraviolet spectrophotometry was adopted to determine the capability of LBP to clear superoxide anions, hydroxyl radicals, DPPH free radicals and ABTS free radicals. The result showed that the law for LBP to clear superoxide anions, hydroxyl radicals and DPPH free radical...

In this study, the antioxidant capacity during UV exposure has been investigated by using a laser-based trace gas detector for the detection of gaseous ethylene as an indicator for lipid peroxidation. Biocream was used as a control and ascorbic acid, butylated hydroxytoluene, phloroglucinol and hydroquinone were added as antioxidants in a mixing concentration of 2.5% (w/w). The experimental res...

The physiological roles played by the tripeptide glutathione have greatly advanced over the past decades superimposing the research on free radicals, oxidative stress and, more recently, redox signaling. In particular, GSH is involved in nutrient metabolism, antioxidant defense, and regulation of cellular metabolic functions ranging from gene expression, DNA and protein synthesis to signal tran...

every firm learns through firm specific methods. this learning process is operationalized by firm’s knowledge management practices. therefore, knowledge to result in successful learning should be assisted by a combinative framework which can enhance a firms’ absorptive capability. this in turn will play a decisive role for achieving competitive advantage. current literature in strategic managem...
