Abstract

The invention relates to a detection and analysis method for a component containing salvianolic acid A. The component containing salvianolic acid A is selected from the medical material of salviae miltiorrhizae, the raw material of salvianolic acid A or pharmaceutic preparations containing the salvianolic acid A. According to the detection and analysis method, high performance liquid chromatography is utilized for detecting and analyzing, so that the accuracy of the content of the salvianolic acid A is ensured and the stability and the no degrading of the salvianolic acid A in the detection can be ensured. Meanwhile, the defects of serious toxicity, harm to human body and high price caused by overuse of acetonitrile are overcome.

Description

technical field [0001] The invention relates to a detection and analysis method containing salvianolic acid A component. Background technique [0002] Salvianolic acid A (Salvianolic acid A), also known as salvianolic acid A, is a water-soluble phenolic acid compound contained in the dry roots and rhizomes of Salviamiltiorrhiza Bunge, a plant of the Labiatae family. Embolism has obvious pharmacological effects, and the effect is better than that of salvianolic acid B (Zhang Hengai. The effect and mechanism of salvianolic acid A on cerebral microvascular embolism in rats [D]. Beijing: Graduate School of Peking Union Medical College, 2011], Salvianolic acid A is formed by the condensation of danshensu and caffeic acid. It contains multiple active groups such as phenolic hydroxyl groups, hydroxyl groups, and ester bonds. It is unstable to light and heat. It is easily oxidized into salvianolic acid C and isodan Due to the above physical and chemical properties of salvianolic ac...
