A successful peanut breeding to obtain genotypes with greater phenolic content requires information on type and content of phenolic compounds in parental peanut genotypes. The aim of this study was to investigate the total phenolic contents and phenolic acid profiles of 15 Valencia-type peanut genotypes both in peanut testae and testa-removed kernels (cotyledons and embryonic axes). Total pheno...

OBJECTIVES Potato (Solanum tuberosum L.), as a whole food, contains high levels of vitamins and important antioxidants including phenolic acids, carotenoids and flavonoids. The objective of this study was to determine the total phenolic content and antioxidant activities of three common potatoes (Solanum tuberosum) cultivars in Iran i.e., Savalan, Agria and Sante. MATERIALS AND METHODS Phenol...

the aim of the study was to evaluate the antioxidant and free radical scavenging properties and to determine the phenolic content of the ethanol extract from five mentha species [m. longifolia (l.) huds., m. piperita l., m. pulegium l., m. rotundifolia (l.) huds., and m. spicata l.]. the antioxidant activities of the extracts were investigated with two different methods, 2,2’-diphenyl-1-picrylh...

plant growth is often limited by low levels of soil micronutrients such as copper (cu), ‎especially in calcareous salt-affected soils of arid and semiarid regions. the aim of this ‎work was to investigate individual and combined effects of salinity and cu on growth, leaf ‎relative water content (lrwc), cell membrane permeability, lipid peroxidation, and total ‎phenolic content (tpc) of rosemary...

A total of fourteen (14) species of wild edible fruits from Burkina Faso were analyzed for their phenolic and flavonoid contents, and their antioxidant activities using the DPPH, FRAP and ABTS methods. The data obtained show that the total phenolic and total flavonoid levels were significantly higher in the acetone than in the methanol extracts.Detarium microcarpum fruit had the highest phenoli...

background: marine algae, especially brown species, produce a wide range of metabolites with various biological activities. objective: since marine algae are rich source of dietary fibers, minerals, proteins, vitamins and phenolic components with antioxidant effect, in addition to the rule of oxidative stress in pathogenesis of chronic diseases, the aim of this study was to investigate possible...

background and purpose: essential oils extracted from different plants are extensively used in perfume, beverage, and food industries and are reported to exhibit antimicrobial activities against a variety of fungi. zhumeria majdae belonging to the lamiaceae family is a rare and endemic medicinal plant species in iran, with a strong and pleasant odor. the leaves of this plant have been used for ...

*Corresponding author e-mail: [email protected] A b s t r a c t. The aim of the present study was to reveal an effective extraction procedure for maximization of the yield of steviol glycosides and total phenolic compounds as well as antioxidant activity in stevia extracts. Ultrasound assisted extraction was compared with conventional solvent extraction. The examined solvents were water (100oC/24 ...

Aqueous extracts of 30 plants were investigated for their antioxidant properties using DPPH and ABTS radical scavenging capacity assay, oxygen radical absorbance capacity (ORAC) assay, superoxide dismutase (SOD) assay, and ferric reducing antioxidant potential (FRAP) assay. Total phenolic content was also determined by the Folin-Ciocalteu method. Antioxidant properties and total phenolic conten...

Aim of the study was to evaluate antioxidant activity and total phenolic content of Achyranthes coynei; an endemic plant used in treatment of several diseases in the same lines that of Achyranthes aspera by traditional practitioners of Belgaum region. Efficiency of extraction methods was studied for aerial parts (leaves, stem, and inflorescence) extracted in methanol using continuous shaking, m...
