objectives: consumption of fruits, such as plums and prunes, is useful in treating blood circulation disorder, measles, digestive disorder, and prevention of cancer, diabetes, and obesity. the paper presents a description of antioxidant and antiradical capacity of plum (prunus domestica l.) in both fresh and dried samples. materials and methods: samples were mixed with methanol and ethanol (as ...

dorema aucheri boiss. (apiaceae) is an endemic plant growing in iran. this plant is used as food and its extracts are recommended for the treatment of a wide range of diseases. to conduct this study, leaf, stem, and flower of d. aucheri were collected from near yasouje, iran. antioxidant and antimicrobialeffects of methanol extracts were measured. further, total phenolic,flavonoid, anthocyanin,...

germination is one of the most effective processes to improve the quality of legumes. vitamins and some other compounds that might be considered beneficial as antioxidants, often change dramatically during the course of germination. antioxidants might be defined as compounds which are capable of preventing, delaying or retarding the development of rancidity or other flavor deterioration in food...

background & aim: strawberry (fragaria vesca l.) is a plant belonging to the rosaceae family with medicinal properties, including antioxidant activity. the present study aimed at investigating the antioxidant properties of strawberry. experimental method: to examine the antioxidant effect, fruit extracts at two phonological stages of growth (ripe and unripe strawberry) were prepared. in add...

The antioxidant activity and phenolic composition of six in vitro cultured blueberry seedlings were determined. Extracts were prepared in 85% ethanol from 30 days old in vitro cultured plants and used to evaluate the antioxidant capacities that included Ferric reducing antioxidant power (FRAP) and 1,1-diphenyl-2-picrylhydrazin (DPPH•) scavenging ability, total polyphenols (TP) and the partial p...

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...

Chokeberries (Aronia melanocarpa) are nowadays believed to exhibit potential cardioprotective and antidiabetic effects principally due to their high content in bioactive phenolic compounds. The stability of the phenolic compounds was studied during different stages of a juice production line and a method for the valorization of pomace was evaluated. Samples were taken from a commercial juice pr...

BACKGROUND The phenolic contents and antioxidant activities of fruits could be underestimated if the bound phenolic compounds are not considered. In the present study, the extraction efficiencies of various solvents were investigated in terms of the total content of the free and bound phenolic compounds, as well as the phenolic profiles and antioxidant activities of the extracts. METHODS Five...

The variation of antioxidant activity and total phenolic content of some plants commonly used as home remedies were screened on the basis of air drying time of (short term and long term air) the dried plant Ocimum sanctum (leaf), Cucumis sativus (Seed), and ethanolic extracts of Capsicum frutescens (Seed) and Coriandrum sativum (Seed). Antioxidant activities and total phenolic content values we...

The effects of guava leaves extracted using solvents of water, ethanol, methanol, and different concentrations of hydroethanolic solvents on phenolic compounds and flavonoids, and antioxidant properties have been investigated. The antioxidant capability was assessed based on 2,2-diphenyl-1-picrylhydrazyl radical and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) radical-scavenging abili...
