METHOD OF ALLOCATION OF SECOISOLARICIRESINOL AND DIHYDROQUERTICIN FROM WOOD (VERSIONS) Russian patent published in 2009 - IPC A61K31/15 A61K31/85 A61K31/352 B01D11/02 

FIELD: medicine, pharmaceutics.

SUBSTANCE: invention concerns a method of wood processing, in particular to a method of secoisolariciresinol and dihydroquerticin allocation from wood of screen zone of larch or fir. The method of secoisolariciresinol and dihydroquerticin allocation from wood in which the crushed wood from the screen zone of larch (Larix) or fir (Abies) is extracted using an antifloating admixture of an organic dissolvent with water, at the certain content of dissolvent, with reception of the extract containing secoisolariciresinol and dihydroquerticin, an extract is processed for removal of the dissolvent with reception of the final admixture containing secoisolariciresinol and dihydroquerticin. Method of secoisolariciresinol and dihydroquerticin allocation from wood, as it is described above, thus an admixture containing secoisolariciresinol and dihydroquerticin subject to a selective extraction and crystallisation with allocation of secoisolariciresinol and dihydroquerticin. The method of allocation of secoisolariciresinol and dihydroquerticin from wood as it is described above, thus an extract containing secoisolariciresinol and dihydroquerticin, is processed for excision of non-polar components, a supernatant liquid is removed, and the obtained remainder is chromatographed on a silica gel layer with the subsequent excision of column effluent, receiving a dry admixture of secoisolariciresinol and dihydroquerticin.

EFFECT: possibility reception to obtain secoisolariciresinol and dihydroquerticin simultaneously from larch or fir wood in the form of their admixture or separately.
