Изучение экстрагирующей способности одно- и двухфазных систем экстрагентов для извлечения флавоноидов из травы клевера лугового

We have studied the extraction of Trifolium pratense L. herbs using aqueous ethanol solutions of various concentration and biphase systems, containing volatile solvents. Dependences of the yield of the active substances on the extractant composition and technological factors have been studied. It is established that the maximum total yield of biologically active substances from Trifolium pratense herbs is reached with the use of biphase solvents systems.
