Abstract

The invention relates to the field of medicine detection, in particular to a high-performance liquid chromatography detecting method for measuring the content of flavonoid compounds and terpene lactone compounds in ginkgo leaves (or ginkgo leaf extract) or preparations of the ginkgo leaves at the same time. The HPLC-DAD-ELSD method is set up, the method can measure the eight flavonoid compounds and three terpene lactone compounds in the ginkgo leaves (or the ginkgo leaf extract) or preparations of the ginkgo leaves at the same time, the measurement result is analyzed, and a new analysis method and a basis are provided for quality control over the ginkgo leaf extract and the preparations of the ginkgo leaf extract.

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 flavonoids and terpene lactones 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 ...
