The invention relates to an asymmetric hydrogenation method for ketone compounds, comprising the step of: under hydrogen atmosphere, in the presence of an in situ catalyst derived from a chiral ligand and a ruthenium salt, adding a ketone compound and a base into a second solvent to carry out an asymmetric hydrogenation for the ketone compound. The invention can obtain a conversion of 100% and a highest asymmetric inducement effect of 99.7% for the ketone compound. The invention has the advantages including simple procedure, high conversion and selectivity, good atom economy and good prospect of industrial application.
