简介 PURPOSE : A production of rare ginsenoside compound Mc, compound Y, and aglycon protopanaxadiol is provided to improve reaction speed because thermostable beta-glucosidase derived from thermostable Dictyoglomus turgidum shows stable activity at high temperature. CONSTITUTION : A composition for preparing rare ginsenosides contains beta-glucosidase as an active ingredient. Ginsenosides include aglycon protopanaxadiol, compound Y, or compound Mc. Beta-glucosidase has an amino acid sequence of sequence number 4. A method for preparing the rare ginsenosides comprises the steps of making beta-glucosidase react with ginsenosides selected among ginsenoside Rb1, Rb2, Rc, and Rd, or a mixture, or a ginseng fine root extract.
