Abstract

The invention relates to a method for preparing traditional Chinese medicine preparations, and particularly relates to a hyperthermic devitalization extraction method of a rhodiola rosea injection. Sofren injection has the effect of promoting blood circulation to remove stasis. According to the method, degrading enzyme in the rhodiola rosea medicinal material is inactivated in a short time in 80-90 DEG C high-temperature water by adopting an extracting technology of feeding materials in 80-90 DEG C high-temperature water, and salidroside is prevented from being decomposed by degrading enzyme in an aqueous solution in a process of heating cold water, and the product yield is improved.

Description
