The invention discloses a detection method for hydroxysafflor yellow A metabolic products. The method includes the steps of: 1) performing intravenous injection to an SD rat with a
safflower extract and
aceglutamide injection, performing orbid
blood sampling, and centrifugally separating the blood sample to obtain
plasma; 2) sucking the
plasma with a micro sample
injector, adding
acetonitrile with volume ratio of
plasma to
acetonitrile being 1:3-3.5, uniformly mixing the substances with vortex and centrifuging the mixture to obtain a supernatant, blow-
drying the supernatant with
nitrogen gas, dissolving the dried substance in
acetonitrile, and centrifuging the solution to obtain a supernatant as a detection sample; and 3) detecting and analyzing the sample through
high performance liquid chromatography-triple quadrupoles linear
ion trap
tandem mass spectrometry, and analyzing the metabolic products in a p-MRM-IDA-EPI mode. In the invention, a p-MRM method is employed in the
mass spectrum with combination of Light
Sight software to quickly identify and analyze the sample for tracing
metabolic change of component change and structure change in the plasma; 11 hydroxysafflor yellow A metabolic products are found in the result. The method can be used for obtaining a time change curve of the hydroxysafflor yellow A and the metabolic product thereof in plasma, and successfully deduces and identifies the molecular structures of seven metabolic products and isomers of the hydroxysafflor yellow A. The method, compared with a
chemical structure analytic method, is more quick and sensitive.
