Abstract

The invention discloses a method for measuring the content of ursolic acid in a glossy privet fruit and astragalus membranaceus healthy energy-strengthening preparation. The method takes an ursolic acid reference substance as a reference and can be used for measuring the content of the ursolic acid in the glossy privet fruit and astragalus membranaceus healthy energy-strengthening preparation at the wavelength being 200-220nm by using a high-performance liquid chromatography. The method is high in specificity and precision, good in repeatability, high in recovery rate and stability and accurate in measurement result, achieves the purpose of effectively controlling the quality of drugs so as to ensure the stable product quality and the safe and effective clinical treatment.

Description

technical field [0001] The invention relates to a method for determining the content of ursolic acid in Zhenqi Fuzheng preparation, belonging to the technical field 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 Zhenqi preparation can improve human immune function, protect bone marrow and adrenal cortex, and promote the production of interferon; in addition, it can also be used in conjunction with radiotherapy and chemotherapy for cancer patients to reduce the toxic and side effects of patients during radiotherapy and chemotherapy, and promote normal function. recover.
