This invention discloses a ginsenoside Rg5 derivative with the molecular formula: C 42 H 74 O 12 The molecular weight is 770.5180. Furthermore, this invention also discloses the synthesis method and application of this derivative. The synthesis method of this invention is simple and safe, and the synthesized ginsenoside Rg5 derivative exhibits strong stability and superior therapeutic effect on non-alcoholic steatohepatitis (NAH). This invention is the first to combine the prepared ginsenoside Rg5 derivative with the PDE4 inhibitor (R)-(-)-Rolipram, showing significantly better efficacy than either drug alone. When the molar ratio of the two drugs is 1:1, the drug exhibits even better therapeutic effect on NHA, showing promising application prospects.
