the reaction of bis[4-hydroxy-3-methoxyphenyl]-1,6-heptadiene-3,5-dione (curcumin) and two novel ligands of bis[4-tetrabenzylglucose-3-methoxyphenyl]-1,6-heptadiene-3,5-dione (bis(tetrabenzylglucose)curcumin) (btbgc) and bis[4-tetraacetylglucose-3-methoxyphenyl]-1,6-heptadiene-3,5-dione (bis(tetraacetylglucose)curcumin) (btagc) with vanadium in methanol, in a 2:1 molar ratio, which yield the co...

understanding the physiological processes associated with drought stress lead to an understanding of the basic mechanisms of resistance, maintaining yield potential and contribute to the identification of drought tolerant cultivars. for this purpose, the effects of drought stress in cowpea genotypes was evaluated using five different genotypes with different yield potential in a pot experiment ...

Costus speciosus (Koen) J.E. Sm. plant and its extracts are used for treatment of fever, snake bites, jaundice, and as a purgative, astringent and antibacterial agent. In the present study, an attempt has been made to evaluate in vitro antioxidant activity of different extracts of this plant by DPPH radical scavenging activity, total antioxidant capacity, nitric oxide scavenging activity, ion c...

Medicinal plants have attracted global attention due to their high levels of antioxidant components for prohibiting or improving various diseases including brain and memory disorders. This study was designed to investigate if the antioxidant effect of Sidr (Zizyphusspina-christi) extract can help to improve the scopolamine induced impairment of memory in Wistar rats. Animals were randomly...

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...
