ethanolic extract of leaves of elaeocarpus ganitrus was analyzed for their total antioxidant capacity, reducing power, metal chelating, abts+ (2, 2-azinobis-(3-ethylbenzothiazoline-6-sulphonate) radical scavenging and hydroxyl radical scavenging activities. the extract at 500 ?g/ml showed maximum iron chelating activity (76.70%) followed by the scavenging of the abts+ radical (55.77%) at the sa...

total phenolic contents (tpc) of five different extracts (petroleum ether, dichloromethane, ethyl acetate, ethanol and ethanol-water) of artemisia biennis willd were measured in this work. the antioxidant activity was investigated by three different methods: β-carotene bleaching (bcb) test, 2,2-diphenyl-1-picrylhydrazyl (dpph) radical scavenging method and ferrous ion chelating (fic) assay. amo...

plants are almost reach sources of phenolic compounds such as flavonoids which are the most importantnatural antioxidants. antioxidant compounds are essential for protecting human body against oxidativestress. however use elicitors could increase the antioxidant activity of plant. the purpose of this studywas to evaluate the effects of chitosan on the content of phenolic and flavonoid compounds...

background and objectives: lamiaceae members have long been used in iranian traditional medicine (itm) for their various medicinal properties. the main objective of this study was to evaluate the antioxidant capacity and antimicrobial activity as well as the total phenolic content (tpc) of the various extracts and fractions of two iranian endemic micromeria (m. persica and m. hedgei). methods: ...

the aim of this study was to evaluate the antibacterial effects of thymus vulgaris, thymus caramanicus, zataria multiflora, ziziphora clinopodioides and ziziphora tenuior against four foodborne and four other bacteria including staphylococcus aureus, shigella dysenteriae, salmonella typhimurium, escherichia coli, staphylococcus epidermidis, bacillus subtilis, mrsa and pseudomona aeruginosa and ...

conclusions due to phenolic content, methanolic extract of m. piperita has moderate antibacterial and antifungal properties against the aforementioned gram positive and gram negative bacteria and fungi strains. materials and methods the methanolic extract was prepared by standard procedure, and total phenol, total flavonoid, and total anthocyanin content were determined using a spectrophotomete...

Olive oil phenolic compounds are potent antioxidants in vitro, but evidence for antioxidant action in vivo is controversial. We examined the role of the phenolic compounds from olive oil on postprandial oxidative stress and LDL antioxidant content. Oral fat loads of 40 mL of similar olive oils, but with high (366 mg/kg), moderate (164 mg/kg), and low (2.7 mg/kg) phenolic content, were administe...

Soluble and bound phenolic compounds were extracted from different varieties of millet types namely, finger millet, foxtail, and proso millet cultivated at dry and intermediate climatic zones in Sri Lanka. The extracts were examined for their total phenolic content (TPC), total flavonoid content (TFC), and proanthocyanidin content (PC). The antioxidant activities were meassured by reducing powe...

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...
