Detection method of medicament for treating epilepsia hyperspasmia, infantile convulsions and prosopospasm

The invention provides a detection method of a medicament for treating epilepsia hyperspasmia, infantile convulsions and prosopospasm. The detection method comprises the step of identifying red-rooted salvia root in the medicament by adopting a thin layer chromatography, wherein the conditions of the thin layer chromatography are that the mixed solution of a solution A and a solution B which are in a volume ratio of (2-6):(0.5-2), preferably 4:1, is used as a developing agent, wherein the solution A is selected from petroleum ether with a boiling range of 60-90 DEG C, petroleum ether with a boiling range of 30-60 DEG C, diethyl ether, cyclohexane, methylbenzene and benzene, preferably the solution A is the petroleum ether with a boiling range of 60-90 DEG C; and the solution B is selected from ethyl acetate, ethyl formate, acetone, chloroform and methyl alcohol, preferably ethyl acetate. The detection method has the advantages of high sensitivity, good repeatability, no interference from negative control, and
