Abstract

The invention provides a method for quantitatively detecting naringin, aurantiamarin, neohesperidin, baicalin and wogonoside in a blood plasma sample by adopting liquid chromatography tandem mass spectrometry, and the method comprises the following steps: (1) preparaing a sample; (2) detecting. The analysis method provided by the invention has good specificity, high precision degree, high accuracy and wide linear range and can be used for in vivo pharmacokinetic determination of Chinese medicinal compositions.

Description

technical field [0001] The invention belongs to the application field of modern traditional Chinese medicines, and in particular relates to a liquid chromatography tandem mass spectrometry detection method for five flavonoid glycosides in blood plasma and an application in pharmacokinetics. Background technique [0002] Mass spectrometry is an analysis method based on the determination of molecular weight. In recent years, its combination with separation mechanisms such as high performance liquid chromatography (HPLC) or capillary electrophoresis (CE) has not only improved its ability to resist interference from impurities and saved analysis time. time, and greatly improved the sensitivity of the assay. The development of soft ionization techniques, such as electrospray ionization (ESI), has expanded the range of molecular weight detection. In addition, electrospray ionization technology can be carried out under atmospheric pressure, which is convenient to connect with liqu...
