The samples of Satureja subspicata Vis. honey were confirmed to be unifloral by melissopalynological analysis with the characteristic pollen share from 36% to 71%. Bioprospecting of the samples was performed by HPLC-DAD, GC-FID/MS, and UV/VIS. Prephenate derivatives were shown to be dominant by the HPLC-DAD analysis, particularly phenylalanine (167.8 mg/kg) and methyl syringate (MSYR, 114.1 mg/...

Bu çalışmada, bal arısı kovanı ürünlerinden olan bal, arı ekmeği, poleni ve erkek larvası (apilarnil)'in toplam fenolik (TPC) flavonoid (TFC) profilleri ortaya konuldu. Bunun yanı sıra söz konusu örneklerin antioksidan aktiviteleri, 2,2′-azinobis (3-ethylbenzothiazolin)-6-sulfphonate (ABTS) assay ferric reducing antioxidant power (FRAP) 1,1-diphenyl-2-picrylhydrazy (DPPH) metotları kullanılarak...

The main intrest of this study was to evaluate the antihemolytic and antioxidant activities aqueous extracts Globularia alypum Zygophyllum album prepared by three different methods: decoction, infusion maceration. Phytochemical tests, total phenolic, flavonoid tannins contents were determined. DPPH radical scavenging assay Ferric Reducing Antioxidant Power (FRAP) employed for evaluation activit...

A series of new 4-(((4-(5-(Aryl)-1,3,4-oxadiazol-2-yl)benzyl)oxy)methyl)-2,6-dimethoxy phenol (6a-i) were synthesized from cyclization of 4-(((4-hydroxy-3,5-dimethoxy benzyl)oxy)methyl) benzohydrazide with substituted carboxylic acid in the presences of phosphorusoxy chloride.The resulting compounds were characterized by IR, 1H-NMR, 13C-NMR, and HRMS data. 2,2-Diphenyl1-picrylhydrazide (DPPH) a...

The aim of this study was to evaluate the anti-oxidant activity of the flowers of the plant Vernonia cinerea (Family: Asteraceae). Flowers extracts of V. cinerea in different four organic solvents (methanol, hexane, chloroform and ethyl acetate) and water were assayed for antioxidant activity using FRAP assay. All of these extracts were found to possess significant antioxidant activity at 5mg/m...

The black walnut, Junglas nigra, is indigenous to eastern North America, and abscission of its fruit occurs around October. The fruit consists of a husk, a hard shell, and kernel. The husk is commonly discarded in processing, though it contains phenolic compounds that exhibit antioxidant and antimicrobial properties. For this study, black walnut husks were extracted using supercritical carbon d...

Plants from Gynura family was used in this study, namely, Gynura procumbens and Gynura bicolor. Gynura procumbens is well known for its various medicinal properties such as antihyperglycaemic, antihyperlipidaemic, and antiulcerogenic; meanwhile, G. bicolor remains unexploited. Several nonenzymatic antioxidants methods were utilized to study the antioxidant capacity, which include ferric reducin...

The aim of this study was to determine the antioxidant potential of the serum and the level of lipid oxidation products in the sera of apparently healthy adult males. The "antioxidant power" of the serum, defined as the ability to reduce ferric ions by antioxidants from the serum (FRAP), was taken as the indicator of total antioxidation potential. The formation of lipid oxidation products was e...

Many health beneficial functions of dietary ingredients, including antimutagenity and anticarcinogenity, have been discussed in relation to their antioxidant properties. In this study, antioxidative mechanisms of whole-apple antioxidants (from seven varieties) were investigated using the 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) radical scavenging capacity assay, the ferric-r...

Pleurotus ostreatus better known as oyster mushroom is widely cultivated and consumed as food in Malaysia. The present study aims to assess the antioxidative potential and total phenolic content of P. ostreatus aqueous extract. The antioxidant activities were evaluated against DPPH and ABTS radical-scavenging activity, ferric-reducing antioxidant power (FRAP) and β-carotene-linoleate bleaching ...
