Abstract

The invention discloses an establishment method for a variable-wavelength fingerprint spectrum of Chinese pulsatilla root decoction granules. The method comprises the following steps of (1) preparing reference substance solutions: preparing reference substance solutions of berberine hydrochloride, palmatine hydrochloride, coptisine, jatrorrhizine hydrochloride, aesculin, aesculetin and pulchinenoside anemoside B4 respectively; (2) preparing a test sample solution: weighing the Chinese pulsatilla root decoction granules, extracting the Chinese pulsatilla root decoction granules and filtering an extracted solution by using a microporous membrane to obtain the test sample solution; (3) obtaining the fingerprint spectrum by determining with high performance liquid chromatography, wherein chromatographic conditions are as follows: octadecylsilane chemically bonded silica is used as a filler by a chromatographic column; gradient elution is adopted; variable wavelengths are detected by ultraviolet light wavelengths; and (4) evaluating similarity: evaluating the fingerprint spectrum of the test sample by "Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese medicine (Edition 2004A)". The method is simple, stable, high in precision and good in repeatability, and can identify the authenticity and merits of products accurately.

Description

technical field [0001] The invention relates to a quality control method of pulsatilla decoction, in particular to a method for establishing variable-wavelength fingerprints of pulsatilla soup particles and a standard fingerprint. Background technique [0002] Pulsatilla Decoction is derived from "Treatise on Febrile Diseases". Its prescription is Pulsatilla, Cortex Phellodendron, Coptidis Rhizoma, and Qinpi four herbs, which have the functions of clearing away heat and detoxification, cooling blood and stopping dysentery (Xie Ming. Fangji Xue. Beijing: People's Health Publishing House, 2002: 134). It is traditionally used for symptoms such as dysentery, tenesmus, purulent blood in the stool, thirst for drinking water, burning anus, red tongue with yellow coating, and rapid pulse caused by heat and toxin deep in the blood. This prescription is a representative prescription for treating damp-heat dysentery. At present, it is mainly used clinically to treat digestive system ...
