Abstract

The invention discloses an analysis method for detecting wogonin, chrysin, oroxylin A, naringenin, hesperetin, berberine, coptisine, jatrorrhizine and palmatine in blood plasma, and applications of the method in pharmacokinetics. The analysis method has good specificity, high precision and accuracy, and wide linear range, and can be used for pharmacokinetic detection in vivo of traditional Chinese medicine compositions.

Description

technical field [0001] The present invention relates to the fields of medicine and chemistry, in particular to liquid chromatography tandem mass spectrometry for the quantitative detection of wogonin, chrysin, melaleurin A, naringenin, hesperetin, berberine, coptisine, drug Follow the method of alkali and palmatine. 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 conv...
