Abstract

The invention discloses a measurement method of a radix astragali granule fingerprint. The measurement method of the radix astragali granule fingerprint comprises the steps of preparation of a test solution, preparation of a comparison product solution, high performance liquid chromatograph measurement, and treatment of data and fingerprint. The invention further discloses the radix astragali granule fingerprint obtained by the method. Compared with the prior art, the radix astragali granule fingerprint obtained by the invention has the characteristics of more peaks, good peak form, good peak separation effect, larger peak area, easiness of verification, high similarity, accuracy and reliability. The method provided by the invention is simple and convenient, fast, accurate, stable and reliable, can be used for the quality control of a radix astragali granule sample, can be used for comprehensively, objectively and scientifically evaluating the quality of radix astragali granules, and provides the foundation and the reference for the rational drug use and further drug efficacy study of the radix astragali granules.

Description

technical field [0001] The invention relates to a method for analyzing fingerprints of traditional Chinese medicines, in particular to a method for measuring HPLC characteristic fingerprints of Astragalus granules and the characteristic fingerprints of Astragalus granules obtained by the method. Background technique [0002] Most of the traditional Chinese medicines and their preparations in my country lack strict quality standards and scientific testing methods, so it is difficult to effectively control their internal quality, cannot guarantee the safety and effectiveness of medication, and do not meet the requirements of the international pharmaceutical market, which seriously restricts the Chinese medicine industry in my country. development of. Strengthening the research on the quality control of traditional Chinese medicinal materials is a key issue in the standardization and standardization of traditional Chinese medicine. Only by carrying out scientific quality contro...
