Honey is a good source of several important chemical compounds and antioxidants and is harvested throughout the year. However, no study has determined how their contents change over the years. The aim of the present research was to investigate the changes in the phenolics, flavonoids and antioxidant properties, as well as other physicochemical properties, of Malaysian acacia honey collected dur...

the present study is conducted in order to investigate the antioxidant capacity of echinophora platyloba dc (duncan) essential oil (eo), growing wild in west azerbaijan, iran, with four different assays. the aerial parts of echinophora platyloba dc were provided from maraghe city district, northwest of iran and its phytochemicals were determined using gc-ms analysis. in order to evaluate and co...

Abstract Phytochemical and antioxidant activity of quinoa flour was evaluated after subjected to gamma irradiation processes at dose 3 6 kGy. Both non-irradiated irradiated samples were successive extractions in ethanol solvent. The treatment investigated via Ferric reducing power (FRAP) radical-scavenging (RSA) using 2,2-diphenyl-1-picrylhydrazyl (DPPH).Total phenolic flavonoid content analyze...

Most of the biological properties myrtle (Myrtus communis L.) are linked to antioxidant activity phenolic compounds present in extracts. In this study, content total phenols, tannins, and anthocyanins acidified ethanol extracts berries leaves five cultivars was quantified during whole fruit development. some development stages, (AA) both tissues evaluated with FRAP, ABTS, DPPH, ?-carotene assay...

Anti-aging cosmetics are often sought after in order to slow down the aging process. Free radicals one of main causes skin aging, and therefore antioxidants used anti-aging cosmetics. The aim this study was investigate which method is most suitable for determining antioxidant capacity these products. Having samples extracted, extracts obtained determined by following spectrophotometric methods:...

The green bean is an important crop worldwide, because it rich in protein, dietary fiber, vitamins, and minerals, as well bioactive compounds that provide with functional properties; however, the composition of many landraces still unknown. purpose this project was to characterize Phaselus vulgaris coccineus L. landrace beans on pH, titratable acidity, total soluble solids, sugars, color parame...

Proanthocyanidins in Chinese bayberry leaves (PCBLs) were qualitatively analyzed. NMR data suggest that PCBLs are mostly composed of (epi)gallocatechin gallate units. Matrix-assisted laser desorption time-of-flight MS data indicate 95 possible prodelphinidin structures, ranging from dimers to tridecamers. Preparative normal-phase HPLC and further analysis by reverse-phase HPLC together with ele...

The objective of this study was to characterize the non-enzymatice and enzymatic antioxidants of E. littorale Blume grown under wild condition. Aerial and sub-aerial parts of the plants exposed to different heat stress was analyzed for the non enzymatic antioxidants such as Tocopherol, Phenols, DPPH, FRAP and enzymatic antioxidants such as Polyphenol oxidase, Peroxidase, Catalase, Super Oxide D...
