Potato (solanum tuberosum L. cv Katahdin) tuber discs treated with arachidonic acid become necrotic and accumulate sesquiterpenoid phytoalexins. The arachidonic acid also causes increases in both phenylalanine ammonia lyase and lignin, but no change in total alcohol-soluble phenols. Linoleic acid does not alter any of these parameters. A high concentration of nonanoic acid promotes both necrosi...

Alternaria solani was a potential leaf spot pathogen of Azadirachta indica L, was isolated from diseased Azadirachta indica L leaves from Nashik and used for the present study. Pathogen was grown on the Czapek-Dox liquid medium substituting or adding different carbon, nitrogen to study phenol production. Considerable variation in the production of total phenol was observed when different carbon...

A modular strategy for the synthesis of hexacyclic dimeric resveratrol polyphenolic benzofurans is reported. The developed synthetic technology was applied to the total synthesis of malibatol A, shoreaphenol, and other biologically relevant poly-phenols.

boraginaceae family is known as a medicinal plant classified in dicotyledons.  it is originated from asia (middle east). the aim of this study was to evaluate ingredient between 4 species of boraginaceae family based on physiological & phytochemical traits as well as seed fatty acid contents.  4 species (e. russicum, e. italicum, e. amoenum, and b. officinalis ) were evaluated carefully. all se...

background and objectives: the seeds of securigera securidaca (l.) deg. & dorf. (fabaceae) are used as anti-diabetic remedy in iranian folk medicine. the aim of the present study was to establish the callus and suspension culture of s. securidaca seeds for the first time and to determine the major secondary metabolites including cardiac glycosides and total phenols. methods: the culture of s. s...

Phenols (phenol and p-cresol) are amino acid metabolites produced by intestinal bacteria. Some reports have demonstrated that the accumulation of phenols in the serum has toxic effects in renal failure patients. In this study, we found that phenols accumulated in the serum of rats given a tyrosine diet, and that dietary intake of a galacto-oligosaccharide mixture (GOS) suppressed the accumulati...

Decomposition of three leaf species (Alnus glutinosa, Eucalyptus globulus and Quercus robur) were examined in a headstream. During two months decomposing leaves were periodically analysed for nutrient content, soluble sugars, phenols, protein precipitation capacity, total fiber, weight loss, microbial and macroinvertebrate colonisation. The leaves of the three species showed similar patterns in...

INTRODUCTION Certain phenols and phthalates are used in many consumer products including personal care products (PCPs). AIMS We aimed to study the associations between the use of PCPs and urinary concentrations of biomarkers of select phenols and phthalates among Californian adults and their children. As an additional aim we compared phenols and phthalate metabolites concentrations measured i...

The effect of delactosed whey permeate (DWP) treatment on antioxidant and phyto-chemical components of canned Irish plum tomatoes were investigated. Tomatoes were sterilised for 5 min (F(0)) at 120 °C and stored for 6 months. The DWP treatment retained significantly (p<0.05) higher levels of ascorbic acid and lycopene of tomatoes. The antioxidant activity of DWP treated tomatoes was higher (7%)...

Pesticides are known to interfere with the biochemical processes of plants, lowering their food quality. The effects of imidacloprid insecticide (a very commonly used pesticide on vegetables) on some biochemical quality control parameters and some enzyme systems (CAT, PPO and POD) were studied. Estimation of imidacloprid residues in potatoes was done by HPLC. It was observed that insecticide tr...
