METHOD FOR PREPARING EXTRACT FRACTION REINFORCED WITH GINSENOSIDES RG1 OR RB1 FROM GINSENG

摘要

The present invention provides a method for preparing an extract fraction reinforced with ginsenoside Rg1 or Rb1 from ginseng. The method for preparing an extract fraction reinforced with ginsenoside Rg1 comprises the steps of: concentrating a spirit extract of ginseng and then adsorbing the extract diluted in water by adding to an adsorption resin; passing distilled water through the adsorption resin, then eluting and removing unadsorbed ingredients; and adding 30-40 v/v% spirits to the adsorption resin to obtain an eluate. The method for preparing an extract fraction reinforced with ginsenoside Rb1 comprises the steps of: concentrating a spirit extract of ginseng and then adsorbing the extract diluted in water by adding to an adsorption resin; passing distilled water through the adsorption resin, then eluting and removing unadsorbed ingredients; and adding 50-80 v/v% spirits to the adsorption resin and then eluting.
