Abstract

The invention discloses a method for determining concentration of licorice glycoside C2 in blood plasma. A liquid chromatography-mass spectrometry system is adopted for determination, firstly, a to-be-determined sample is taken, a certain quantity of organic solvent protein precipitation solutions are added, a chromatographic column is used for separation after pretreatment, and a mass spectrometry detector is used for detection. The method is rapid, accurate, high in sensitivity, simple and convenient to operate and suitable for determining the concentration of licorice glycoside C2 in the blood plasma.

Description

technical field [0001] The invention belongs to the technical field of biological detection, and in particular relates to a method for measuring the concentration of liquiritin C2 in blood plasma. Background technique [0002] Licorice glycoside C2 is a new flavonoid compound isolated from the dry root and rhizome of Glycyrrhiza uralensis Fisch., a perennial herb of the genus Licorice. In vitro experiments have proved that liquiritin C2 has significant anti-ulcer, anti-AIDS, anti-inflammatory and other biological activities, and is a new drug source compound with good development prospects. Its structural formula is as follows: [0003] [0004] There is no literature report on the in vivo assay method of liquiritin C2. The invention establishes a method for measuring liquiritin C2 in rats, and conducts exploratory research on drug metabolism of liquiritin C2 through the method. Contents of the invention [0005] Purpose of the invention: Aiming at the problems exist...
