The invention relates to the technical field of
drug metabolic
component analysis, in particular to a method for detecting in-vivo prototype components and metabolic components of a dripping
pill with a refreshing and refreshing
throat. According to the present invention, based on the GC-MS and the UHPLC / Q Exactive Plus MS technology, the detection method of the
in vivo prototype component and the metabolic component is established; wherein the non-volatile prototypes and metabolites are detected by adopting UHPLC-MS / MS (
Ultra High Performance Liquid
Chromatography-
Mass Spectrometry /
Mass Spectrometry) according to the following specific conditions: chromatographic conditions: an LC (Liquid
Chromatography)
system: Vanquishhorizon; the
chromatographic column is Hypersil gold, 2.1 * 100 mm, 1.9 [mu] m; the
column temperature is 40 DEG C; the sample size is 1 [mu] L; the flow rate is 0.3 mL * min <-1 >; the composition and gradient of a mobile phase are as follows: A: 0.1%
formic acid-
acetonitrile, and B: 0.1%
formic acid-water; the
mass spectrum conditions are as follows: an MS
system:
Orbitrap Explores 240; the scanning mode is HESI + amp; hESI <->; the taper hole
voltage is 3.5 kV (HESI-), and the taper hole
voltage is 2.5 kV (HESI-); the temperature of the
solvent removing gas is 350 DEG C; the atomization gas is 50 arb;
solvent gas removal: 10 arb; the capillary tube is 320 DEG C; the scanning range (m / z) is 100-1500; the resolution ratio (MS) is 70000; and the resolution ratio (MS / MS) is 15000. The patent develops a method for identifying in-vivo prototype
drug components and metabolites of the in-vivo prototype
drug components, and the
metabolic pathway and
excretion rule of the drug can be determined through analysis, so that a scientific basis is provided for
quality control of a preparation and fundamental research of pharmacological substances.
