Abstract

The invention belongs to the technical field of traditional Chinese medicine component detection and provides a method for determining the content of nineteen components in radix stephaniae tetrandraeand astragalus membranaceus soup by ultra-high performance liquid chromatography-tandem mass spectrometry. The method comprises the following steps of pespectively preparing a test solution, a reference solution and a mixed standard solution; detecting the mixed standard substance solution by ultra-high performance liquid chromatography-tandem mass spectrometry, drawing a standard curve and a test solution, performing mass spectrometry positive and negative ion mode analysis by ultra-high performance liquid chromatography-tandem mass spectrometry, and obtaining the contents of nineteen components in the radix stephaniae tetrandrae and astragalus membranaceus soup according to the standard curve. The method is high in sensitivity and good in reproducibility; analysis accuracy and reliability, 19 chemical components in the radix stephaniae tetrandrae and radix astragali soup can be quantitatively detected at the same time; formononetin, formononetin, calycosin-7-one, calycosin-7-one, pterocarpan, pterocarpan, isoflavane, liquiritin, glycyrrhetinic acid, tetrandrine, tetrandrine, atractylodes lactone I, atractylodes lactone II I, isoflavane, astragaloside I, astragaloside II, astragaloside III and astragaloside IV.

Description

technical field [0001] The invention belongs to the technical field of detection of traditional Chinese medicine components, and in particular relates to a method for determining the contents of nineteen components in Fangji Huangqi Decoction by ultra-high performance liquid chromatography tandem mass spectrometry. Background technique [0002] Fangji Huangqi Decoction was first recorded in "Synopsis of the Golden Chamber". The whole prescription is composed of Fangji, Astragalus, Atractylodes macrocephala, licorice, ginger, and jujube. In recent years, the clinical application of Fangji Huangqi Decoction mainly focuses on chronic heart failure, cardiogenic edema, rheumatoid arthritis, chronic glomerulonephritis, nephrotic syndrome and other diseases. to receive more and more attention. However, most of the existing studies focus on the clinical and pharmacological effects, and less research on its chemical constituents. In order to better study Fangji Huangqi Decoction, e...
