METHOD OF ANTIVIRAL PREPARATION GIPORAMINE PREPARING (VERSIONS)

摘要

FIELD: medicine, pharmacy. SUBSTANCE: invention relates to preparing preparation form sea buckthorn (Hippophae rhamnoides L.) leaves with content of gallo-elago-tannins > 20% by method of pre-extraction of vegetable raw with polar organic solvent followed by extraction of end compounds with aqueous organic extractant. From sea buckthorn depleted raw with content of gallo-elago-tannins > 20% active substances are extracted with anhydrous polar extractant, then with aqueous polar extractant followed by additional purification from by-side substances by extraction of aqueous vat residue after removal of extractant with binary mixture of solvents containing aliphatic alcohol and aliphatic hydrocarbon solvent of hexane type. Invention ensures to obtain standard preparation from raw of different types. EFFECT: improved method of preparing. 2 cl, 1 tbl
