Preparation method of ginsenoside Rg1

[0068] The Panax notoginseng total saponins obtained by the extraction of Panax notoginseng were dissolved in water, filtered, the filtrate passed through the HPD-400A macroporous adsorption resin column, washed with water, the eluent was discarded, eluted with 20% ethanol, the eluate was collected, concentrated, and dried. Dissolve the dry matter in water, filter, and pass the filtrate through the HPD-400A macroporous adsorption resin column, wash with water, discard the eluent, then elute with 10% ethanol, discard the eluent, elute with 20% ethanol again, collect The eluate was concentrated and dried to obtain ginsenoside Rg 1 The crude product is extracted by adding organic solvent acetone, the extract is filtered, the filtrate recovers the solvent to dryness, and the residue is dried to obtain ginsenoside Rg 1 .

[0069] The method for extracting total saponins from Panax notoginseng is prepared according to existing patent documents or scientific documents.
