Abstract
The present invention relates to a method for selectively producing compound K and compound Y, which are originally present in ginseng in a trace amount, from saponins of ginseng, and more specifically to a method capable of obtaining desired target compounds, that is, compound K and compound Y, in high yields, by treating saponins, obtained from ginseng, with particular enzymes to structurally convert the saponins.
Claims7
A method for producing compound K of the following Chemical Formula 1 and compound Y of the following Chemical Formula 2 from ginseng saponins comprising Rb1, Rb2, Rc and Rd, said method comprising converting the ginseng saponins to compound K and compound Y by contacting the ginseng saponins with enzymes, said enzymes comprising;
- a) pectinase obtained from Aspergillus aculeatus;
- and
- (b) pectinase obtained from Trichoderma reesei,
- to produce a reaction mixture comprising compound K and compound Y as conversion products:
- Compound K, where Glc is β-D-glucopyranosyl;
- Compound Y, wherein Glc is β-D-glucopyranosyl and Arap is α-L-arabinopyranosyl.
