Background and Aims: To evaluate the effect of temperature on wheat streak mosaic virus (WSMV) resistance phenotype, through total protein, phenol, and peroxidase activity in bread wheat, a factorial experiment was conducted using Adl-Cross (resistant) and Marvdasht (susceptible) cultivars. Materials and Methods: Results showed that incubation at 32C changed the gene expression for resistance ...

Mosses contain active constituents that exhibit various biological activities. This study provides additional information on the potentials of mosses as natural sources of biologically active compounds that can be used as medicines. The antioxidant potential of Bryum billardieri Schwaegr. (Bryaceae) is herein studied by analyzing its total phenol content and its radical scavenging activity. Eth...

as sorgoleone (Einhellig and Souza, 1992; Einhellig et al., 1993; Weston et al., 1997) and phenolic acids (BenThe total phenol pool (kg ha21) of the aerial parts and roots of Hammouda et al., 1995; De Raissac et al., 1998) to the sorghum (Sorghum bicolor L. cv. CE145266) crops and their relationships to dry matter and total phenol concentrations (g kg21) were soil by decomposing crop residues (...

objectives this study was designed to determine the chemical composition, in vitro antioxidant activity, and total phenol content of various extracts of s. chloroleuca. materials and methods dried aerial parts of the plant were crushed, then sequentially extracted with n-hexane, ethyl acetate, and methanol. the fractions of s. chloroleuca were subjected to silica gel column chromatography and s...

inflammation is a part of the non-specific immune response which occurs in reaction to any type of injury. medicinal mushrooms have had application in various disorders including cancer, liver injuries, inflammation and diabetes. in the present study, the anti-inflammatory effects of the aqueous extracts of medicinal mushrooms (fomes fomentarius, ganoderma applanatum and trametes hirsuta) were ...

Iron-containing materials have been prepared following several strategies of synthesis and using different silica supports (amorphous, zeolitic and mesostructured materials). Activity and stability of these materials was evaluated on the wet peroxide oxidation of phenol under mild reaction conditions (100 degrees C, air pressure of 1MPa and stoichiometric amount of hydrogen peroxide for the com...

The nitro phenol compounds are the largest and widely known group of industrial chemicals in use today. These compounds are organic molecules that contain at least one –NO2 group attached to the aromatic ring [1]. Nitrophenols are commonly used in pharmaceuticals, wood preservatives, rubber chemicals, dyes, pigments, explosives and industrial solvents [2]. O-nitrophenol (ONP) and m-nitrophenol ...

Seaweed has potential as a source of bioactive compounds, food and medicine. One the seaweeds that to be used for its compounds is brown seaweed Sargassum plagyophyllum. Fractionation technique separating grouping chemical content extracts based on their polarity. This study aims determine components (secondary metabolites) flavonoids, alkaloids, steroids/terpenoids, saponins phenols qualitativ...

Phenol and phenolic compounds are environmental pollutants present in industrial wastewaters such as coal tar, oil refineries and petrochemical plants. Phenol removal from industrial effluents is extremely important for the protection of environment. Usually, phenol degradation is carried out by physicochemical methods that are costly and produce hazardous metabolites. Recently, phenol biodegra...
