Vitex doniana (West African plum or black plum) is a plant with varying phytoconstituents and biological activities across different countries. In this study, essential oils extracted from the leaves fruits of cultivated in Ghana were investigated for their antimicrobial antioxidant activities. The actions determined using hydrogen peroxide (H2O2), phosphomolybdenum, thiobarbituric acid reactiv...

In this study, we measured free radicals and thiobarbituric acid-reactive substances (TBARS) in hepatocellular carcinoma and in non-cancerous liver parenchyma. There was a higher concentration of free radicals in malignant tissue than in non-cancerous tissue. In contrast, the level of TBARS was significantly (P < 0.01) lower than non-cancerous liver parenchyma. These paradoxical results suggest...

INTRODUCTION Thiobarbituric acid-reactive substance is a marker of oxidative stress and has cytotoxic and genotoxic actions. C- reactive protein is used to evaluate the acute phase of inflammatory response. OBJECTIVES To assess the thiobarbituric acid-reactive substance and C-reactive protein levels during extracorporeal circulation in patients submitted to cardiopulmonary bypass. METHODS T...

This research work aimed to enhance the concentration of some bioactive compounds in culantro (Eryngium foetidum L.) plantlets through gamma irradiation (0.0, 10.0, 20.0 and 40.0 Gy range) treatments. Gamma irradiation at 40.0 Gy significantly stimulated total phenolic, flavonoids, tannin and saponin contents. The effect of irradiation on antioxidant properties of culantro extracts was investig...

Chlorpyrifos, O,O'-diethyl-O-3,5,6-trichloro-2-pyridyl phosphorothionate, exposure in rats caused significant inhibition of acetylcholinesterae activity in different regions of brain and generated oxidative stress as evidenced by increase in the level of thiobarbituric acid reactive substances and decrease in the ratio of reduced to oxidized glutathione in all the three regions of brain. Malond...

The effect of aqueous ethanol (1:1) extract of the calyx of Hibiscus sabdariffa on carbon tetrachloride (CCl4) induced liver damage was investigated. Oral administration of the extract following a single CCl4 dose promoted the healing of oxidative liver damage as determined by serum aminotransferases, ALT, AST, levels and liver thiobarbituric acid reactive substances levels. It appeared from th...

The essential oils, isolated by hydrodistillation from the leaves, seeds and rhizomes of Heracleum sprengelianum (Wight and Arnott), collected from the Western Ghats of Peninsula India, were analyzed by gas chromatography (GC) and gas chromatography coupled to mass spectrometry (GC–MS). The antioxidant property of these oils was tested, with and without peroxidation inducer, through the egg yol...

Introduction: The use of pomegranates in Moroccan pharmacopeia is due to their healing and nutritional properties because richness secondary molecules. following study analyses the composition aqueous extract Punica granatum peel evaluates vivo vitro antioxidant effects, hemolytic protection, acute toxicity. Methods: Quantification plant was realized by high-performance liquid chromatography (H...

to the TBARS assay. In particular, different aldehydes can be formed in the lipid peroxidation process and aldehydes other than MDA may form chromogenic complexes with TBA, which exhibit similar absorbance or emission wavelengths. Several other biological compounds, including sugars, amino acids and bilirubin, are also reactive towards TBA and form TBA reactive materials which confound the meas...
