Problems solved by technology

However, due to the more complex components in the decoction, the separation of various chemical components is often not high during liquid phase detection; at the same time, some components in the decoction, such as sugars, will also affect the baseline Large impact, resulting in unstable baseline and poor chromatographic results
[0005] At present, there is no report of decocting Atractylodes macrocephala for HPLC fingerprint analysis

Abstract

The invention discloses a detection method for atractylodes macrocephala koidz medicinal materials. The method adopts HPLC (high performance liquid chromatography) fingerprint spectrum for detection and includes the operation steps of: (1) preparing sample solution; (2) preparing reference solution; and (3) respectively and precisely absorbing the sample solution and the reference solution to inject into a liquid chromatograph so as to elute by taking an acetonitrile-water system as a flowing phase and detect at wavelengths of 248+ / -5nm. After the atractylodes macrocephala koidz medicinal materials are decocted with water, and then the HPLC fingerprint spectrum is applied for detection, so that quality of the atractylodes macrocephala koidz medicinal materials can be reflected more truly. Moreover, chromatographic conditions such as the flowing phase are selected specifically, so that chromatogram baselines are stable and convenient to integrate, resolution of characteristic peaks is good, and similarity among different medicinal materials is high. The detection method for the atractylodes macrocephala koidz medicinal materials can be effectively used for quality control of atractylodes macrocephala koidz and provides a guarantee of medication security of the atractylodes macrocephala koidz medicinal materials.

Description

technical field [0001] The invention relates to a detection method of Atractylodes macrocephala medicinal material, in particular, it is a detection method using HPLC fingerprint spectrum. Background technique [0002] Atractylodes macrocephala is the dry rhizome of Compositae (Atractylodes macrocephala Koidz.), which tastes bitter, sweet, and warm in nature. Atractylodes macrocephala is a commonly used medicinal material in traditional Chinese medicine. However, the current pharmacopoeia for the identification of Atractylodes macrocephala only involves simple identification methods such as traits and thin layers, and cannot provide an intuitive method for identifying the authenticity of Atractylodes macrocephala. [0003] At present, high performance liquid chromatography technology is a commonly used quantitative and qualitative detection method in the quality inspection of traditional Chinese medicine, which can intuitively analyze the authenticity of medicinal materials....
