A method for complex processing of medicinal herbs by sequential extraction of air-dry grounded raw materials with solvents with different dielectric constants, such as water and hydrophilic and hydrophobic organic solvent, and at each stage of extraction from the second one, meal is extracted after removing from it of previous solvent and extraction is carried out in 6 stages sequentially with water at a temperature of 90-95 ° C, the dielectric constant of the solvent under 75-51, 50-26, 11.25, 10-1 at a temperature of 18-25 ° C and acidified and salted or alkali aqueous solution at a temperature of 60-80 ° C. |
