[0025] Preparation of the reference substance solution: Accurately weigh an appropriate amount of the dehydrodrycodine reference substance, and dissolve it in methanol to make a reference substance solution with a concentration of 126.88 μg / mL;
[0026] Preparation of the test solution: take 10 mg of the composition, accurately weigh it, dissolve it with 80% methanol and set the volume in a 10mL measuring bottle, as the test solution;
[0027] Determination method: Precisely draw 10 μL each of the reference substance solution and the test solution, inject it into a liquid chromatograph, measure it, and obtain it.
[0028] A method for determining the total alkaloids of the quaternary ammonium corydalis of the pharmaceutical composition containing dehydrodrytidine as described above, which utilizes the following ultraviolet colorimetric method for determination, comprising:
[0029] Preparation of the reference substance solution: Take an appropriate amount of dehydrodrycodine,...

[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 ...
