AB - A method for preparing carbon material by carbonizing walnut shell at 700 °C is developed. The sorbent surface is negatively charged. Using scanning electron microscopy it is found that in carbonization the structuring of the sample surface occurs. A method for isolating flavonoids from the herb of St John’s wort (Hypericum perforatum L.) is optimized. The content of the sum of flavonoids in terms of rutin equivalent is 20–50 mg%. The phytocomposition is prepared and the structure of the obtained phytosorbent is studied; the degree of immobilization of biologically active substances is determined.
