PROCESS FOR PREPARING EXTRACT FRACTION ENRICHED WITH GINSENOSIDE RG3 FROM GINSENG RADIX

摘要

A method of preparing a ginseng radix extract fraction enriched with ginsenoside Rg3, the method including: enriching with ginsenoside Rg3 a ginsenoside Rb1-containing Ginseng Radix ethanol extract by reacting the ethanol extract with a mixture of water and acetic acid; adsorbing the ethanol extract enriched with ginsenoside Rg3 to an adsorption resin; allowing distilled water to go through the adsorption resin to elute components that are not adsorbed; adding 30 to 50 v/v% ethanol to the adsorption resin to remove non-saponin components and triol ginsenosides except for ginsenoside Rg3; and adding 50 to 100 v/v% ethanol to the adsorption resin to obtain an eluate.
