This study aimed to appraise the chemical features such as total phenol (TP), total flavonoid (TF), total antioxidant capacity based on 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays of bran and grain in 10 genotypes of rice (Oryza sativa L.) grown in Iran. Based on two procedures of DPPH and FRAP, the results demonstrated that in terms of the amount of...

The influence of harvesting date on some physicochemical properties of nectarine (Prunus persica var. Red gold) fruit including fruit weight, pigment content, total carbohydrate, total phenol and antioxidant activity were studied. Fruits were harvested in four different stages; a) two weeks after fruit set, b) pit hardening, c) three weeks after pit hardening and 6 weeks after pit hardening. Re...

one-year-old seedlings of olive cultivars, zard, roghani, koroneiki and manzanilla, were transplanted to different sets of pots each pot containing 2000g of sterilized sandy loam soil. the experiment was conducted in a completely randomized design of 32 treatments, each in five replications. treatments were comprised of: control, mere nematode, mere fungus, and fungus+nematode. pots were inocul...

Cathodic hydroxylation of organoboron compounds was successfully performed under an oxygen atmosphere, producing the corresponding phenol derivatives with high selectivity and efficiency.

wheat streak mosaic virus (wsmv) causes extensive economic damage to wheat (triticum aestivum l.) in many regions of the world. the present study was conducted to find out if the variations in biochemical changes in reaction to wsmv infection in f2 generation of either potentially resistant (adl-cross) or susceptible (marvdasht) cultivars are genetically inherited. a factorial experiment was em...

In the domestic cat (FeZis catus) phenol is converted mainly to phenylsulphate with only small amounts of phenylglucuronide [l] . The cat’s ability to form the glucuronides of foreign compounds is low compared with other species [2] and it forms little or no glucuronide with phenol [I], benzoic acid [3], sulphadimethoxine [4] , or 1-naphthylacetic acid [5]. It was of interest therefore to find ...

In the present study, new Schiff's base derivatives: (Z)-4-amino-5-(2-(3- fluorobenzylidene)hydrazinyl)-4H-1,2,4-triazole-3-thiol (Y1), (Z)-3-((2-(4-amino-5- mercapto-4H-1,2,4-triazol-3-yl)hydrazono)methyl)phenol (Y2), (Z)-2-((2-(4-amino-5- mercapto-4H-1,2,4-triazol-3-yl)hydrazono)methyl)phenol (Y3) and 3-((Z)-(2-(4- (((E)-3-hydroxybenzylidene)amino)-5-mercapto-4H-1,2,4-triazol-3-yl)hydrazono)m...

We investigated the effects of phenolic and phenol compounds on 3,3',5-L-125I-triiodothyronine (125I-T3) binding to purified Xenopus laevis transthyretin (xTTR) and to the ligand-binding domain of X. laevis thyroid hormone receptor beta (xTR LBD), on T3-induced metamorphosis in X. laevis tadpoles and on the induction of T3-dependent reporter gene in a X. laevis cell line. Of the halogenated phe...
