[0059] The HPLC fingerprint spectrum assay method of embodiment one Shuanghe decoction standard decoction

[0060] 1.1 Instruments and reagents

[0061] instrument:

[0062]

[0063] Reagent:

[0064]

[0065] 1.2 Sample preparation:

[0066] 1.2.1 Preparation of samples and sample solutions for testing

[0067] (1) Preparation of samples: Weigh nine medicinal materials according to the prescription ratio, crush them, and sieve them through a 10-40 mesh sieve to obtain coarse powder; take three times the prescription amount of coarse powder into a fully automatic decoction pot, accurately measure 900mL pure water and pour Put it in, soak for 30min, decoct for 75min, stir three times during decoction, filter it with 300 mesh filter cloth while it is hot, the volume of filtrate is about 500mL, mix the filtrate evenly, take one-third of it and dilute it into a 250mL volumetric flask with pure water It is the stock solution of the standard soup, and it is for later use. ...

Abstract

The invention provides a HPLC fingerprint spectrum measurement method for standard double-harmonizing decoction, belonging to the technical field of traditional Chinese medicine. The method comprises the following steps: (1) preparing a test sample solution; (2) preparing a mixed reference solution; (3) preparing a single medicine negative reference solution; (4) precisely absorbing the test sample solution, the mixed reference solution and the single medicine negative reference solution respectively and injecting into a high performance liquid chromatograph and measuring to obtain the liquid chromatogram of the test sample solution, the mixed reference solution and the single medicine negative reference solution; and (5) performing data matching on the liquid chromatogram of the test sample solution, the mixed reference solution and the single medicine negative reference solution by use of the traditional Chinese medicine chromatographic fingerprint spectrum similarity evaluation system formulated by the Chinese committee of pharmacopeia to obtain a standard fingerprint spectrum. According to the invention, the quality of standard granules of double-harmonizing decoction is effectively controlled, the curative effect of the drug is guaranteed, and more formal quality control is realized on the classical famous prescription.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicines, in particular to an HPLC fingerprint determination method of Shuanghe decoction standard decoction. Background technique [0002] Shuanghe Decoction was first recorded in Volume 5 of "Taiping Huimin Hejiju Prescriptions" in the Southern Song Dynasty. It is a new prescription for Baoqing to treat all deficiency. The original prescription is recorded as white peony (seven and a half), angelica (washed, soaked in wine), astragalus (honey-roasted), Chuanxiong, rehmannia glutinosa (cleaned, wine-steamed, three liang each), licorice (broiled), cinnamon (removed Skin, no fire, two and a half cents each). The above is fine powder, two qian per serving, one and a half cups of water, three slices of ginger, one jujube, decocted for six minutes, hollowed out, and taken before eating. Treat men and women with five fatigues, six extremes, and seven injuries, with deficiency of heart an...
