FIELD: pharmaceuticals.
SUBSTANCE: invention relates to the pharmaceutical industry, in particular, to a method for fractionation of the bioflavonoids complex of sea buckthorn meal. The method for fractionation of the bioflavonoid complex of defatted sea buckthorn meal consists in isolating the flavonol fraction by the method for adsorption column chromatography of a bioflavonoid solution produced by dissolving a dry extract of the bioflavonoid complex of defatted sea buckthorn meal in ethyl alcohol 96% vol. in a ratio of 1:10 while heating to complete dissolution, with elution on silica gel for 4 hours, wherein ethyl alcohol with a decreasing concentration: 96%, 75%, 50%, 25%, is used as an eluent.
EFFECT: above invention provides a possibility of eliminating the disadvantages of the previous technology level and simplifying the technology.
