The processes of deep oxidation during the reaction of rutin and quercetin with HAuCl4 under anaerobic conditions at temperatures of 30, 60, and 100 °C were studied. The formation of CO and CO2 was revealed by mass spectrometric analysis to occur at temperatures ≥30 °C. Since the processes of oxidation of quercetin and rutin are similar, it was concluded that, on the one hand, the sugar residue of...
A new procedure for the preparation of biocompatible gold nanoparticles using bioflavonoids: rutin, quercetin, and luteolin as reducing agents and stabilizers was proposed. On varying the bioflavonoid concentration, nanoparticles of different size are formed. By the combined use of spectroscopy and atomic force microscopy, the nanoparticle size was estimated (40–50 nm). Uniform and highly dispersed...
