Abstract

The invention discloses a method for measuring the content of polysaccharides in a glossy privet fruit and astragalus membranaceus healthy energy-strengthening preparation. The method takes anhydrous dextrose as a reference substance and can be used for measuring the content of the polysaccharides in the glossy privet fruit and astragalus membranaceus healthy energy-strengthening preparation at the wavelength being 480-490nm by using a phenol-sulfuric acid method or at the wavelength being 600-625nm by using an anthrone-sulfuric acid method. The method is simple and convenient to operate, good in quick reproducibility, high in recovery rate and sensitivity and accurate in measurement result, and can be used for effectively controlling the quality of the glossy privet fruit and astragalus membranaceus healthy energy-strengthening preparation so as to ensure a clinical treatment effect of the glossy privet fruit and astragalus membranaceus healthy energy-strengthening preparation.

Description

technical field [0001] The invention relates to a method for determining the content of polysaccharides in Zhenqi Fuzheng preparation, belonging to the technical field of traditional Chinese medicine quality detection. 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 dosage forms of Zhenqi preparation for clinical selection include tablets, capsules, granules and dropping pills. [0003] Astra...
