Embodiment 1

[0047] Example 1: Example 1 provides a liquid chromatography mass spectrometry detection method for sterol hormones, liquid conditions: WatersUPLC BEH C8 1.7um2.1mm × 10mm, the aqueous phase is 0.5mM ammonium fluoride aqueous solution, and the organic phase is pure methanol . The program of the gradient system is: 0-0.5 minutes, the water phase is 60%; the 4th minute, the water phase is reduced to 45%; the 7.5 minute, the water phase is reduced to 25%; the 8.2 minute, the water phase is reduced to 10%; At 8.3 minutes, the water phase is 2%, and at 9-10 minutes, the water phase is 60%. Mass spectrometry conditions: ion source temperature 600°C, desolvated gas 1100L / Hr, using multiple reaction monitoring mode.

[0048] In Example 1, the ion source temperature of the liquid chromatography tandem mass spectrometer in step 02 was set to 600°C.

[0049] In Example 1, the desolvation gas of the liquid chromatography tandem mass spectrometer in step 02 is adjusted according to the t...

Abstract

The present invention proposes a method for separating multiple groups of isomers and detecting 29 kinds of steroid hormones. By optimizing the mobile phase and elution conditions of ultra-high performance liquid chromatography, multiple groups of isomers can be separated , by optimizing the liquid phase conditions and mass spectrometry parameters, different steroid hormones with a content span of ng to pg levels can be detected simultaneously, and the simultaneous detection of the content of 29 steroid hormones including multiple groups of isomers in the sample is realized.

Description

technical field [0001] The invention relates to the technical field of steroid hormone detection, in particular to a method for separating multiple groups of isomers and detecting 29 steroid hormones. Background technique [0002] Steroid hormones mainly include adrenocortical hormones and sex hormones. Among them, adrenal cortex hormones include mineralocorticoids and glucocorticoids, and sex hormones include progesterone, androgen, and estrogen. [0003] Steroid hormones are obtained from cholesterol through a series of enzyme catalysis, which are all cyclopentane polyhydrophenanthrene derivatives in structure, with many structural similarities and even isomers (such as 17-hydroxyprogesterone and 11- Deoxycorticosterone, 11-deoxycortisol, 21-deoxycortisol and corticosterone, testosterone and epitestosterone, androsterone and epiandrosterone, etc.), and the hormone content in the human body is widely distributed in ng-pg level, estrogen and Aldosterone and other contents ...
