Embodiment
[0033] 1. Extraction and preparation of compositions containing dehydrodrycardine
[0034]Rhizoma Corydalis, pulverized, added 14 times the amount of 80% ethanol to reflux and extracted 3 times (6 times, 4 times, 4 times), each time for 4 hours, combined the extracts, filtered to remove the dregs, and recovered the ethanol from the filtrate until it had no alcohol smell. The medicinal solution is properly diluted with deionized water, passed through the X-5 macroporous adsorption resin, and the medicinal solution is adsorbed by the resin column at a flow rate of 2 ml / min. After the adsorption is completed, the non-adsorbed impurities are first washed away with 2% ammonia solution. Then elute with 50% ethanol solution, collect the alcohol eluate, concentrate the eluate under reduced pressure, and dry it in vacuum below 60°C. Compositions of dehydrodrytidine. This composition contains 57.40% of quaternary ammonium total alkaloids, including 14.05% of dehydrodrylamine, 4.06% of ...

Abstract
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.
Description
technical field [0001] The present invention relates to a kind of anti-myocardial ischemia and hypoxia-resistant pharmaceutical composition, specifically, it is dehydrodrycardine and mainly contains African tetrandrine, 13-methyl dehydrogenation cordydamine, dehydrogenation cordydine The application of bulbine, palmatine, etc. in the preparation of anti-myocardial ischemia and hypoxia-resistant drugs belongs to the field of medical technology. Background technique [0002] Corydalis yanhusuo (Corydalis yanhusuo W.T.Wang), commonly known as Yuanhu, was first recorded in "Supplements to Materia Medica". It has the effects of promoting qi and relieving pain, promoting blood circulation and removing blood stasis. The chemical components of Corydalis are mainly alkaloids, which can be divided into tertiary amine bases and quaternary ammonium bases according to the nature of its amino nitrogen. So far, most of the alkaloids found in its tubers are tertiary amine bases. , while th...
