The invention relates to a preparation method of Gandakang capsules, and belongs to the preparation method of traditional Chinese medicines. According to the invention, after a new process is determined, through study and dynamic detection of three batches of
pilot-scale products, the character identification of the product and
thin layer identification of four medical materials are determined, and an HPLC (high-performance liquid
chromatography) measuring method for peoniflorin content is also built; and according to the above quality standards, the feeding process, and
processing steps from the intermediate
processing to finished
product processing are effectively controlled in the improved production process of the Gandakang capsules, thus the product quality is guaranteed. The Gandakang capsules has the effects of obviously resisting aminotransferase increase caused by CCl4 and D-
galactosamine, relieving the degree of
liver injury caused by chemical substances, and protecting liver
cell membrane; and the Gandakang capsules also has the effects of improving
phagocytosis function of mice and the generation of
antibody for mouse
hemolysin caused by sheep erythrocyte, thus the product can better improve mouse immune function, and the new
dosage form of Gandakang capsules has good liver protection effect and has better
treatment effect if applied clinically.
