Abstract

The invention relates to the field of medicine detection, in particular to a method for simultaneously determining the contents of multiple components in a Shuxuening injection. By adopting the method, the contents of 14 flavonoid glycoside compounds and 2 phenolic acid compounds in the Shuxuening injection can be simultaneously determined, and the new analysis method and a basis are provided for quality control of commercially available Shuxuening injections.

Description

technical field [0001] The invention relates to the field of drug detection, more specifically, the invention relates to a high-performance liquid chromatography detection method for simultaneously determining the contents of multiple components in Shuxuening injection. Background technique [0002] Shuxuening Injection is clinically used for the treatment of cardiovascular diseases and peripheral circulatory disorders, and works through multiple targets and multiple links. It can reduce the cardiovascular risk caused by high homocysteine ​​(Hcy); reduce the pro-inflammatory factor plasma C-reactive protein (CRP) related to the occurrence, evolution and development of atherosclerosis; reduce the strong vasoconstriction and Thromboxane B2 (TXB2) that promotes platelet aggregation; reduces serum lipid peroxide (LOP), which can cause various damages to the structure and function of cells and cell membranes; reduces endogenous vasoconstrictor activity widely present in various t...
