Abstract

The invention relates to a method for detecting the content of effective ingredients of rhodioloside, calycosin-7-glucoside, specnuezhenide and formononetin. The method is high performance liquid chromatography by using rhodioloside, calycosin-7-glucoside, specnuezhenide and formononetin as reference substances and methanol: water / 0.01-5% phosphoric acid aqueous solution / 0.01-5% formic acid aqueous solution / 0.01-5% glacial acetic acid aqueous solution in a ratio of (5-100):(95-0) or acetonitrile: water / 0.01-5% phosphoric acid aqueous solution / 0.01-5% formic acid aqueous solution / 0.01-5% glacial acetic acid aqueous solution in a ratio of (5-100):(95-0). Compared with the prior art, the method has the advantages that the content of four effective ingredients can be simultaneously detected along with comprehensive quality representation, strong specificity, high stability and accurate measurement result, the aim of effectively controlling the quality of a modified preparation can be achieved, and stability of related product quality and clinical administration safety of the preparation can be guaranteed.

Description

technical field [0001] The invention relates to a content determination method of salidroside, calycosin glucoside, privetin and formononetin in Zhenqi Fuzheng preparation, and belongs to the technical field of traditional Chinese medicine quality detection. Background technique [0002] The prescription of Zhenqi Fuzheng preparation is composed of Ligustrum lucidum and Astragalus membranaceus, which have the effects of strengthening the body, nourishing qi and nourishing yin. It has been clinically applied and proved that it is a good immune function enhancer at present, and it can improve human immune function. Protect bone marrow, adrenal cortex and liver function, suitable for the recovery of various diseases caused by wasting, chronic illness (cirrhosis, chronic atrophic gastritis, diabetes, tuberculosis, etc.), postoperative and postpartum patients; radiotherapy and chemotherapy for cancer patients During the period, it has the effect of adjuvant therapy, which can sig...
