Problems solved by technology

However, there are many types of preparations with similar functions on the market, and it is difficult to guarantee their quality. Therefore, special preparation methods and quality inspection methods are needed to ensure their quality.
[0005] At present, the TLC identification method of Clematis clematis and the content determination method of ephedra have been recorded, but the content determination method adopts TLC scanning method, the technology is relatively lagging, the method is relatively rough, and the reproducibility is not ideal, and the TLC scanning method is in the It has been rarely used in the current drug detection technology. Although the prior art has reported the use of high performance liquid chromatography to detect ephedrine hydrochloride in traditional Chinese medicine preparations containing ephedra, the method is relatively cumbersome

Abstract

The invention discloses a traditional Chinese medicine preparation containing herba ephedra and a quality detecting method for ephedrine hydrochloride thereof. The traditional Chinese medicine preparation is prepared from radix clematidis and the herba ephedra. The method is capable of qualitatively detecting the ephedrine hydrochloride in the preparation by using a thin-film chromatographic analysis method, and has the advantages of strong separating power, high sensitivity, rapid separating speed, convenient color development, and simpleness and convenience in operation. The high performanceliquid chromatography is used for assaying the content of the ephedrine hydrochloride in the preparation, wherein a detection wavelength is 272 nm, at this moment the absorption of an ephedrine hydrochloride reference substance is maximum and blank liquid has no interference, so a detecting result is accurate and reliable, and the quality of a product can be accurately controlled; acetonitrile-methyl alcohol-0.1% glacial acetic acid of which a volume ratio is (0.5 to 2) : (3 to 5) : (93 to 96.5) is used as a mobile phase for preparing a reference substrate solution and a test example solution, and the peak shape and a separation degree of the ephedrine hydrochloride are good. The traditional Chinese medicine composition can be further prepared into multiple preparations, and the administration and carrying needs of a patient in different illness states are satisfied.

Description

technical field [0001] The invention relates to the field of compound medicinal preparations and analysis, in particular to a traditional Chinese medicine preparation containing ephedra and a quality detection method for ephedrine hydrochloride thereof. Background technique [0002] Ephedra is the dry herbaceous stem of Ephedra sinica Stapf, Ephedra intermedia Schrenk et C.A.Mey. or Ephedra equisetina Bge. Also known as Sedaoma, Jieligen, etc. Ephedra pungent, slightly bitter, warm. Return lung, urinary bladder channel. Ephedra can produce sweat and dispel cold, ventilate the lung and relieve asthma, promote diuresis and reduce swelling, and is used for anemofrigid cold, chest tightness, wheezing and coughing, feng shui edema; bronchial asthma. Honey ephedra nourishes the lungs and relieves cough. It is mostly used for symptom resolution, asthma and cough. [0003] Clematis chinensis Osbeck, Clematis hexapetala Pall. or Clematis manshurica Rupr. dry roots and rhizomes o...
