Abstract
The invention discloses a method for producing ginsenoside Rh4 by utilizing panaxatriol ginsenoside through large-scale conversion, belonging to the field of biochemical industry. The method comprises the following steps: dissolving the panaxatriol ginsenoside in deionized water in a fermentation tank, introducing N2 for protection, then carrying out online sterilization, adding an organic acid solution and a heteropoly acid HxYW12O40-nH2O catalyst with a Keggin structure and a certain catalytic amount, wherein Y is selected from the group consisting of P, Si, Fe or Zn, and x is 3 or 4 and n is a positive integer of 0 to 30, then carrying out a directional conversion reaction under the protection of N2 at a constant temperature and in a constant pressure, and finally collecting a reaction product and carrying out purifying so as to obtain high-purity ginsenoside Rh4, wherein the condition of online sterilization is at 121 DEG C for 20 min; N2 is introduced for protection before online sterilization; and added organic acid is a combination of one or more selected from the group consisting of lactic acid, malic acid, citric acid, alpha-ketoglutaric acid, succinic acid, trans-butenoic acid and pyruvic acid. The method provided by the invention has the advantages of simple and practicable process, fewer side reactions, high product purity and facilitation to industrial production.
