Abstract

The invention discloses a quality control method of Sijunzi (Chinese name) decoction. The content of ginsenoside Rg1, ginsenoside Re, ginsenoside Rb1 and glycyrrhizic acid is measured at the same time by the high performance liquid chromatography; the content measurement method of the four ingredients comprises the following steps of: preparation of a reference solution, preparation of a test solution and content measurement, wherein the ginsenoside Re, the ginsenoside Rg1, the ginsenoside Rb1, and glycyrrhizic acid in the ammonium glycyrrhetate content in set values respectively are 12.0mg, 10.0mg, 18.0mg and 28.0mg. The quality standard is simple, and the quality of a drug can be better controlled. The quality control method disclosed by the invention is strong in specificity and good in reproducibility, so that the security, effectiveness and quality control of the drug are really reflected.

Description

technical field [0001] The invention relates to the field of quality control of traditional Chinese medicine preparations, in particular to a quality control method for Sijunzi Decoction. Background technique [0002] Sijunzi Decoction is derived from "Taiping Huimin Mixture Bureau Prescription", which is used to treat spleen and stomach qi deficiency. It is the basic prescription for treating spleen and stomach qi deficiency. In the prescription, ginseng is the king, which is sweet, warm and invigorating, invigorating the spleen and nourishing the stomach. Atractylodes macrocephala is bitter and warm, invigorates the spleen and dries dampness, strengthens the power of invigorating qi and assisting transportation, and is a ministerial drug. Poria cocos is sweet and light, invigorating the spleen and expelling dampness, and it is an adjuvant drug; cocoons and rhizomes are used together to invigorate the spleen and eliminate dampness. Roasted licorice is sweet and warm, nour...
