Abstract

The invention discloses a method for rapidly and sensitively combined-testing Vitamin K1 by isotope dilution ultra-high performance liquid chromatography, wherein the method includes steps of (1), preparing reference substance solution of Vitamin K1 and isotope internal standard solution of Vitamin K1; (2), setup up a standard curve of the Vitamin K1; (3), sampling chromatogram of a sample solution to be tested; (4), determining the concentration of the Vitamin K1 in the sample to be tested. When the method for combined-testing Vitamin K1 by isotope dilution ultra-high performance liquid chromatography is used for test the Vitamin K1 in serum, the method is simple and rapid, high in accuracy, strong in specificity, high in accuracy, and good in sensitivity.

Description

technical field [0001] The invention relates to a rapid and sensitive determination of vitamin K by isotope dilution ultra-high performance liquid chromatography-mass spectrometry 1 Methods. Background technique [0002] Vitamin K 1 Also known as phytonadione, it is a fat-soluble vitamin and is an essential substance for the synthesis of prothrombin in the human liver, which can promote the precursor of prothrombin (factor II) and other coagulation factors (factor VIII, IX, X) Substance carboxylation reaction, and then converted into prothrombin and the corresponding coagulation factors. Clinically, it is commonly used in the treatment of skin and mucous membrane bleeding, internal bleeding, bleeding after trauma surgery, neonatal bleeding and other deep tissue bleeding. In addition, vitamin K 1 It is also involved in bone metabolism and cell growth, and has the effects of analgesia and relieving bronchospasm. Vitamin K 1 The detection method can be applied in many asp...
