METHOD FOR PRODUCING TOTAL SAPONINS FROM MANCHURIAN ARALIA ROOTS Russian patent published in 2016 - IPC A61K36/25 A61K125/00 B01D11/02 

FIELD: pharmaceutics.

SUBSTANCE: invention relates to chemical-pharmaceutical industry, particularly to production of sum of saponins from Manchurian Aralia roots (Aralia mandshúrica Rupr. et Maxim, Araliaceae-Araliaceae family). Method for producing total saponins from Manchurian Aralia roots, in which ground roots of Aralia three times extracted by aqueous-alcoholic mixtures with concentration of ethyl alcohol 40-70 %, evaporated to aqueous residue, acidified with 10 % solution of hydrochloric acid solution is filtered through a layer of polyamide, washed with purified water to neutral reaction, target substance is eluted with 95 % ethanol, the obtained alcohol eluate then evaporated to volume equal to half of the raw material weight, mixed with acetone and 25 % ammonia solution is added in droplets with intense mixing to pH = 7-8; Aralia saponins precipitate is filtered, washed with acetone and chloroform.

EFFECT: described above method enables to isolate sum of saponins with increased content of target substances in ready product, reduce number of producing steps and technological process duration.
