FIELD: medicine, pharmaceutics.
SUBSTANCE: invention relates to pharmaceutical industry, in particular to obtaining luteolin 7,3'-disulphate. Method of obtaining luteolin 7,3'-disulphate, by extraction of sea grass of family Zosteraceae by ethylene at defined conditions, extract is evaporated, obtained concentrate is solved in distillated water, filtered or centrifuged, filtrate is acidified by hydrochloric acid, stood for a day, sediment is removed, then solution is applied on column with polychrome-1, sorbent is washed with distillated water, and target product is eluted with water solution of ethylene, then alcohol is removed from eluate, target product is dried on spray-type or lyophilic dryer.
EFFECT: method makes it possible to extend spectrum of biologically active substances from available, common sea raw material.
