The invention discloses an enzymatic synthesis method of ginsenoside Rh2. The method comprises the following steps: ginsenoside Rg3 is used as a substrate, glucosidase derived from Terrabacter ginsenosidimutans is added in order to carry out a catalytic reaction for forming ginsenoside Rh2; the temperature of the catalytic reaction is 25-50 DEG C; the pH value is 6.5 to 9.5. The method for producing ginsenoside Rh2 is simple, the reaction selectivity is high, and the by-products are few. The glucosidase and a mutant thereof are easily obtained by fermentation of Escherichia coli, the production cost and product quality are superior to those of a chemical method, and the method is suitable for industrial production. The reaction conditions are mild and the method belongs to an environmentally friendly production process, which accords with the national green environmental protection industry standards.
