Stevia rebaudiana B. extracts as a low-calorie sweetener have gained worldwide approval. Synthesized nanoparticles by plant were used in different programs such as medical, pharmaceutical and agricultural filed. Here, we report the increase of the main glycosides of stevia plant with silver nanoparticles (AgNPs) treatment. This fact has stimulated the research on the analysis and comparison of ...

Antioxidants are compounds which can prevent biological and chemical substances from oxidative damage by reactive oxygen species. Flavonoids are the most important class of polyphenolic compounds that because of their antioxidant characters possess biological activities and pharmacological effects. Chrysin-6-C-fucopyranoside and chrysin-3-malonyl-6-C-fucopyranoside are mono C-glycosyl derivativ...

Whether hydrolytic or synthetic, glycosyl transfer is, simply in terms of quantity, one of the most important biological reactions on earth. The formation and cleavage of glycosidic bonds are catalysed by glycosyltransferases and glycoside hydrolases which are crucial for a number of biological pathways (biosynthesis and degradation of structural and storage polysaccharides, cellular signalling...

Wild and fantastical animals climb, fly, scamper, prance across pictorial stone carvings decorating Eastern Han tomb doors in northern Shaanxi. Alongside dragons other mythical animals, bears felicitously dance, tigers grin opening their mouths to roar, wild frolic swirling cloudscapes. While the same can be found reliefs mortuary art regions, frequency, emphasis on plasticity movement, combina...

      Tribulus terrestris L. var. orientalis (Kerner) G. Beck is widely used in the traditional medicine of many countries. Several flavonoides are identified from the plant material. Aerial parts which collected from northeast of Iran are used in this study. Three flavonoid glycosides were isolated and characterized. The flovonoids were found to be based on quercetin...
