The addition of synthetic antioxidants to oils and/or foods is one of the most efficient ways to prevent lipid oxidation. However, the safety of synthetic additives has been questioned stimulating the evaluation of naturally occurring compounds with antioxidative properties. Although there is no assurance of the safety of natural antioxidants, there is some comfort knowing that such antioxidant...

background and objectives: edible parts of pomegranate fruits are a rich source of bioactive compounds. the present research examines the effect of modified atmosphere packaging on the fruit physico-chemical and microbial properties of two commercial pomegranate cultivars grown in iran. materials and methods: the arils were packaged and stored under four different atmospheres. all of the packag...

salicylic acid (sa) and methyl jasmonate (meja) as phytohormone regulate synthesis of secondary metabolites in a wide range of plant species thereby accumulation of phenylalanine ammonia lyase enzyme (pal) and accelerate of oxygen free radicals, protein kinas and no production. the present research designed to evaluate effect of sa and meja elicitation on accumulation of phenolic compounds, fla...

Decoctions, macerations and fumigations of the stem bark and wood of Terminalia brownii 20 Fresen. are used in traditional medicine for fungal infections and as pesticides on field crops and in 21 traditional granaries in Sudan. In addition, T. brownii is commonly used for protecting wooden 22 houses and furniture. Therefore, using agar disc diffusion and macrodilution methods, eight extracts 2...

The formation of crown gall tumors by Agrobacterium tumefaciens requires that the virulence (vir) genes be induced by chemical signals which consist of specific phenolic compounds and monosaccharides, synthesized at plant wound sites. Signal transduction in the activation of these genes is mediated by the VirA-VirG two-component regulatory system, together with ChvE, a glucose-galactose binding...

Olive processing wastewaters (OPW), namely olive mill wastewater (OMW) and table-olive wastewaters (TOW) were evaluated for their antibacterial activity against five Gram-positive and two Gram-negative bacteria using the standard disc diffusion and thin layer chromatography (TLC)-bioautography assays. Disc diffusion screening and bioautography of OMW were compared to the phenolic extracts of ta...

BACKGROUND The study of phenolic compounds profiles and antioxidative activity in ginseng fruit, leaves, and roots with respect to cultivation years, and has been little reported to date. Hence, this study examined the phenolic compounds profiles and 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free-radical-scavenging activities in the fruit, leaves, and roots of Korean ginseng (Panax ginseng Meyer) a...
