Abstract

The present invention discloses a quality control method of asthma tablets, which includes the flowing steps: (1) chromatography conditions and system suitability experiment; (2) preparation of control solution; (3) preparation of test solution is as following: taking the product, removing the coating, porphyrizing, taking about 1g, placing into a 50ml volumetric flask, adding 1ml of ammonia test solution and 25ml of chloroform precisely, weighing the weight, carrying out the ultrasonic treatment with the power of 260w and the frequency of 40KHz for 30 minutes, cooling, weighing the weight, using the chloroform to supplement the loss weight, shaking evenly, filtering, sucking 5ml of filtrate precisely, adding 2ml of 2 percent hydrochloric ethanol anhydrous, shaking evenly, drying up by evaporation in a water bath, adding 10ml of 0.1percent hydrochloric acid in the residual slag, full dissolving by ultrasound, filtering, and taking the subsequent filtrate; (4) weigh and suck the control solution and the test solution precisely and respectively to inject to an HPLC instrument for determination. The method adopts the HPLC to carry out the content determination of morphine, codeine phosphate and ephedrine hydrochloride in the prescription under a same system, which can not only ensure the efficacy of the products, but can also enable the quality of the products to be stable.

Description

technical field [0001] The invention belongs to the field of quality control of traditional Chinese medicine preparations, in particular to a quality control method of asthma tablets. Background technique [0002] Asthma tablets are composed of poppy shell, bellflower, ephedra, and licorice four herbs, which have the effect of relieving cough and relieving asthma, and are used for cough and asthma. Poppy shell and ephedra are the main medicines in the prescription, mainly used to treat cough and asthma. Morphine in poppy shell is one of the active ingredients in the prescription, but it is also highly addictive. Codeine phosphate in poppy shell and ephedrine hydrochloride in ephedra are also active ingredients in the prescription. These three indicators The amount of the content directly affects the curative effect of the product. Platycodon grandiflorum and licorice as raw materials, if not identified, will affect the quality of the product. However, the original standar...
