The method of biochemical synthesis of metals nanoparticles in inverse micelles
using natural biologically active compounds, from flavonoids groups as reductants has been
substantiated. An extraction of rutin from green tea and onion peel was carried out. Quantitative
content of rutin in investigated objects was determined by photocolorimetric method. A synthesis of
copper nanoparticles in inverse micelles by biochemical method has been carried out.
