The invention discloses a method for preparing a rhizoma corydalis decumbeutis total alkaloids acid salt freeze-drying substance, which comprises the following steps: a) using supercritical CO2 total alkaloids extract of rhizoma corydalis decumbeutis as a raw material, adding acid water solution into the raw material to dissolve the raw material so as to obtain acid water solution of rhizoma corydalis decumbeutis total alkaloids; and b) filtering the acid water solution of the rhizoma corydalis decumbeutis total alkaloids obtained in the step a) or filtering the acid water solution after centrifugating, and freeze-drying the clarified solution to obtain the rhizoma corydalis decumbeutis total alkaloids acid salt freeze-drying substance. The obtained rhizoma corydalis decumbeutis total alkaloids acid salt freeze-drying substance has the characteristics of good water solubility, easy operation, high effective component content and the like, and is in powder shape. The invention also discloses application of the
