Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the current quality standard of Corydalis sylvestris is relatively backward, and there are only traits and thin-layer identification items without any content measurement index, so it is impossible to accurately and effectively identify Corydalis sylvestris and control the quality of finished medicines. Provide a quality detection method of Tibetan medicinal material Corydalis cypress

Abstract

The invention provides an identification method for a Tibetan herb Saibei Corydalis. The identification method comprises the following steps: preparing a reference sample, preparing a test sample, and acquiring a fingerprint map of the Saibei Corydalis through high-performance liquid chromatography, wherein the chromatographic conditions and the system suitability test are as follows: octadecylsilane bonded silica is used as a filler; acetonitrile is used as a mobile phase A, an aqueous solution containing 0.2% glacial acetic acid and 0.5% triethylamine in percentage by volume is used as a mobile phase B, the pH value of the mobile phase B is 6.0, and gradient elution is performed; the detection wavelength is 285nm; counted by an original protopine peak, the number of theoretical plates is not be less than 3000. The identification method for the Saibei Corydalis is simple and convenient, and high in reproducibility and accuracy; as long as the selected herb has the fingerprint map specified in the application, the herb is confirmed as the Saibei Corydalis, therefore, the accuracy of herb selection is ensured and further the quality of a finished medicine is further ensured.

Description

technical field [0001] The invention relates to an identification method of a medicinal material, in particular to an identification method of a Tibetan medicinal material Corydalis sergei. Background technique [0002] There are about 320 species of Corydalis in the world, mainly produced in Asia. There are about 200 species in my country, and they are distributed all over the country. Corydalis saibei is the dried whole plant of Corydalis saibeiensis (also known as Corydalis saibeiensis), which is distributed in Qinghai, Tibet, Gansu, Sichuan and other places. It is a commonly used drug in Tibetan medicine, and the data shows that 25% It is used in the treatment of various hemorrhage, hepatitis, cholecystitis, influenza and other diseases. It is also used to treat bruises or other trauma, fever, gastroenteritis and so on. [0003] Judging from the current research results on the chemical components of this genus, this genus mainly contains prototropines, protoberberines, ...
