Problems solved by technology

Although "Chinese Pharmacopoeia" records the specific content determination method of privet privet glucoside, there is no record for the content determination method of privet privet in the existing Zhenqi Fuzheng preparation, Therefore, the existing quality inspection standard of Zhenqi Fuzheng preparation is incomplete and inaccurate, and it is urgent to provide a method for the determination of the content of the specific privetin component in Zhenqi Fuzheng preparation.

Abstract

The invention discloses a method for determining specnuezhenide content in a Zhenqifuzheng preparation. Taking specnuezhenide standard as contrast, the method can determine the specnuezhenide content in the Zhenqifuzheng preparation by high-performance liquid chromatography by selecting a solution containing methanol and a mixed solution with a ratio of (20-50):(80-50) or a mixed solution containing acetonitrile and the mixed solution with a ratio of (5 to 35):(95-65), wherein the mixed solution consists of water, 0.01% to 5% of phosphoric acid water solution, 0.01% to 5% of glacial acetic acid, 0.01% to 0.5% of methanoic acid water solution. Compared with the prior art, the method provided by the invention has the advantages of high specificity, high precision, high repeatability, high yield, high stability, and accurate result by adopting high-performance liquid chromatography, and can effectively control the preparation quality, thereby ensuring the stability of product quality as well as clinical safety and effectiveness.

Description

technical field [0001] The invention relates to a method for determining the content of privetin in Zhenqi Fuzheng preparation, and belongs to the technical field of quality detection of traditional Chinese medicines. Background technique [0002] Zhenqi preparations have the effects of invigorating qi and nourishing yin, strengthening the body and strengthening the foundation. Modern pharmacological experiments have proved that it can improve the immune function of the human body, protect the function of bone marrow and adrenal cortex, and promote the production of interferon; cooperate with radiotherapy and chemotherapy of tumor patients, reduce the toxic and side effects of patients during radiotherapy and chemotherapy, and promote the recovery of normal functions. Its prescription consists of Astragalus and Ligustrum lucidum. At present, the commonly used dosage forms of Zhenqi preparations for clinical selection include tablets, capsules, granules and dropping pills. ...
