The present invention relates to a method for preparing intestinal metabolites of compound K and ginsenosides as active ingredients by treating polysaccharide degrading enzymes with ginseng, and in detail, pectinises, which are polysaccharide degrading enzymes in rice, red ginseng, red ginseng, and ginseng extracts. Treated with Pectinex or Viscozyme to break down the glycosides of saponins in ginseng, and 20- O -β-D-glucopyranosyl-20 ( S ) -protopanaxatriol ( Ginsenoside F1, PG-1), PG-2, 20- O- [α-L-arabinopyranosyl- (16) -β-D-glucopyranosyl] -20 ( S ) -protopanaxadiol (Compound Y, PG-3) And a method for preparing 20- O- β-D-glucopyranosyl-20 ( S ) -protopanaxadiol (Compound K, PG-4) in bulk. |
