Salinity is an important environmental factor that limits plant growth and production. Grape is classified as salt sensitive plants. The object of this study was to evaluate effects of salinity on membrane lipid peroxidation, antioxidant components, and antioxidative enzymes activity in ten grape genotypes native to the regions around Urmia Salt Lake.Malondialdehyde content and protective enzym...

Decoction and 75% ethanolic extracts from the leaves of Acanthopanax trifoliatus (AT) and Toddalia asiatica (TA) were spectrophotometrically examined for antioxidant activity and phenolics content. Phytochemical characteristics of the decoction extracts were also investigated by thin layer chromatography (TLC). The leaf decoction extract of AT significantly exhibited the highest in vitro antiox...

The present work describes the phytochemical study on Ferula lutea flowers. Total phenolics and flavonoids of the n-butanol and ethyl acetate extracts were quantified (phenolics [40.68-52.29 mg gallic acid equivalent/g of dry weight], flavonoids [12.38-14.72 mg quercitin/g dry weight]). Two diastereoisomers were isolated and identified using spectroscopic techniques (1D, 2D NMR and GC-MS). The ...

We have investigated the electrochemical oxidation of a number natural phenolics (salicylic acid, m-hydroxybenzoic acid, p-hydroxybenzoic acid, protocatechuic acid, o-coumaric acid, m-coumaric acid, p-coumaric acid, caffeic acid, quercetin and rutin) using cyclic voltammetry. The antioxidant properties of these compounds were also studied. A structural analysis of the tested phenolics suggests ...
