Here, we test the dissolution of Rhodiola granules (RG) in vitro, draw dissolution curves of salidroside, gallic acid, and ethyl gallate in ultrapure water, and fit the curves to different mathematical models. This protocol provides information and guidance for in vivo bioequivalence and in vivo-in vitro correlation studies of RG.
