| titleOfInvention | Ginsenoside AL-beta-di-xyloxide and its preparation method by enzymatic method |
| abstract | The present invention relates to ginsenosides Re-beta-di-xylosides and methods for their preparation. Ginseng saponins are classified as panaxanadiol (PD) saponins and panaxanatriol (PT) saponins according to the basic structural characteristics of sapongenin. Among the panaxanadiol-based saponins, there is a saponin component in which xylose is bound as a constituent sugar, but a saponin component in which xylose is bound as a constituent sugar has not been found to date.n n n The present invention relates to the preparation of two new saponin compounds in which xylose is bound to Re by reacting with ginsenoside Re, which is contained in a large amount in the root or ground of ginseng as a substrate, with an enzyme having a sugar transfer activity. In other words, when ginsenoside Re and para-nitrophenyl-beta-xylopyranoside were reacted with the enzyme cellulosease, xylose beta was added to the fourth carbon of glucose bound to the saponenin carbon 6 of Re. Xylose is bound to the sixth carbon of glucose bound to saponenin carbon 6 of Re when reacted with one of the derivatives bound to one form of enzyme, enzyme beta-galactosidase. It relates to the production of one derivative.n n n Two ginsenosides Re-beta-di-xyloside prepared by the present invention has been found to be a novel saponin, which is simple to react, can be prepared in a short time, and is not known until now. |
