The invention relates to a 
medicine composition containing dehydrogenated corydaline as well as a preparation method and a measurement method. The 
medicine composition is a composition which is mainly prepared by a method for extracting a medicinal material of 
corydalis tuber through the thermal refluxing of 
ethanol and purifying the 
corydalis tuber by macroporous adsorptive resin, and comprises dehydrogenated corydaline, total 
quaternary ammonium hydroxide, columbamine, 13-methyldehydrocorydalmine, dehydrocorybulbine and 
palmatine, wherein the content of the dehydrogenated corydaline, which is measured by using a high-efficiency liquid 
chromatography method, is not lower than 10 percent; the content of the total 
quaternary ammonium hydroxide in the composition, which is calculated according to the dehydrogenated corydaline, is not lower than 50 percent; and the measurement method comprises a measurement method to the dehydrogenated corydaline and a measurement method to the total 
quaternary ammonium hydroxide of the 
corydalis tuber. The 
medicine composition containing the dehydrogenated corydaline as well as the preparation method and the measurement method have the characteristics of simple production process, short production period, high safety, no 
pollution to the environment, low cost, high yield and the like, and are especially suitable for industrialized 
mass production; and the medicine composition containing the dehydrogenated corydaline can be used for lowering the degree of 
myocardial infarction and has the functions of obviously resisting 
myocardial ischemia and obviously prolonging the anoxia-proof time of a rat.
