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 an alcohol extract of ginseng and then adsorbing the extract diluted in water by adding the extract to an adsorption resin passing distilled water through the adsorption resin, then eluting and removing unadsorbed ingredients and adding 30 to 40 v/v% alcohol to the adsorption resin to obtain an eluate. The method for preparing an extract fraction reinforced with ginsenoside Rb1 comprises the steps of: concentrating an alcohol extract of ginseng and then adsorbing the extract diluted in water by adding the extract to an adsorption resin passing distilled water through the adsorption resin, then eluting and removing unadsorbed ingredients and adding 50 to 80 v/v% alcohol to the adsorption resin and then eluting.
