Oxidative stress is developed due to susceptibility of biological substrates to oxidation by generation of free radicals. In degenerative diseases, oxidative stress level can be reduced by antioxidants which neutralize free radicals. Primary objective of this work was to screen four medicinal plants, namely, Andrographis paniculata, Costus speciosus, Canthium parviflorum, and Abrus precatorius,...

Aegle marmelos, Bilwa (AM) and Psidium guajava, Guava, (PG) leaves were screened for phytochemicals by sequential extraction using a series of solvents. The antioxidant components such as β-carotene, α-Tocopherol, glutathione, ascorbic acid, total polyphenols and flavonoids were also analyzed. In addition, the leaves were extracted with methanol (ME), ethanol (EE) and water (WE) and the polyphe...

Background Diabetes mellitus type 2 (DM2) is associated with increased oxidative stress and oxidative damage to DNA. An appropriate intake of antioxidants via the diet can improve this disturbed oxidative status [1]. Apples are the most widely consumed fruits in Europe and represent a major source of antioxidants due to their high polyphenol content [2]. Apple pomace as a polyphenol-rich byprod...

Polyphenols, ubiquitously present in the food we consume, may modify the gut microbial composition and/or activity, and moreover, may be converted by the colonic microbiota to bioactive compounds that influence host health. The polyphenol content of fruit and vegetables and derived products is implicated in some of the health benefits bestowed on eating fruit and vegetables. Elucidating the mec...

The development of the parameters of ozone decontamination method assuring the least possible losses of biologically active substances (essential oils and polyphenols) and their activity in common juniper (Juniperus communis (L.)) berries was studied. Ozone treatment in dynamic bed was conducted 9 times. The process was conducted under different ozone concentrations (100.0; 130.0; 160.0 g O3/m3...

This work reports the application of a voltammetric electronic tongue system (ET) made from an array of modified graphite-epoxy composites plus a gold microelectrode in the qualitative and quantitative analysis of polyphenols found in wine. Wine samples were analyzed using cyclic voltammetry without any sample pretreatment. The obtained responses were preprocessed employing discrete wavelet tra...

to study the effect of salinity on physiological and morphological traits of chickpea in 2010 at faculty of agriculture and natural resources, university of tehran with seven chickpea genotypes. two experiments design was rcbd with 3 replications and 5 levels of salinity stress (ctrl, 200, 150, 100, 50 mm) for laboratory experiment on germination indices and greenhouse experiment on physiologic...

We determined the foliage yield, polyphenol content, and yield of weekly greenhouse-cultivated major varieties sweet potato with aim to utilize as a source. The two-year study was conducted using five from May November 2012, Kokei No. 14, Koganesengan, Murasakimasari, Tamaakane, Suioh, three October 2014, Beniharuka. Koganesengan Beniharuka in 2014 significantly higher than other varieties. con...
