the aim of the present study was to compare three reducing sugars (d-glucose, d-arabinose, d-mannose) with respect to the antioxidative activity characteristics of their caramelisation products (cps) prepared by monitoring uv-absorbance, browning intensity, ferric ion reducing capacity, fe2+ ion chelating activity as well as dpph radical scavenging activity. moreover, the effect of cps from d-g...

(Thiazolyl-2-yl)hydrazones (THs) are a group of organic compounds containing both hydrazone and 1,3-thiazole pharmacophores present in many approved drugs. They have been investigated greatly recent years due to potent anticancer, antibacterial, antifungal, antituberculosis, anti-inflammatory, antiparasitic activities. In this study, one pyridine-based two quinoline-based, novel THs were synthe...

the traditional extraction method was used to evaluate the antioxidant properties of nettle leaves in soybean oil. also the effects of three different solvents (water, 80% methanol and chloroform) on the extraction content of phenolic and flavonoid compounds from nettle leaves were examined. water extract had the highest extraction yield, and chloroform extract had the highest extraction conten...

We newly synthesized organic selenium compounds (5-membered ring compounds) including 2-selenoxo-1,3-thiazolidin-4-ones (compounds A) and 3-alkoxy-4,5-dihydro-5-selenoxo-1H-1,2,4-triazole-1-carboxylates (compounds B). To address whether these compounds show antioxidative effects, we also examined their superoxide radical (O(2) (-))-scavenging effects. Moreover, we examined the eff...
