and calycosin. In this study, we used ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) combining multiple reaction monitoring (MRM) technique for the simultaneous determination of five isoflavones in rat plasma
and rapid ultra-performance liquid chromatography–tandem mass spectrometry (UPLC–MS/MS) method for the simultaneous determination of atractylenolide I, II, and III in rat plasma [ 1 ]. Plasma samples were processed by liquid–liquid extraction with
years, liquid chromatography–mass spectrometry (LC–MS) or liquid chromatography–tandem mass spectrometry (LC–MS/MS) has become a mature technique with many applications to various biological matrixes in cortisol and cortisone analyzing fields [ 11 – 18
use a rapid method to determine the true molecular structure of such compounds. Mass spectrometry (MS) has been widely used for the structural determination of flavonoids [ 21 , 22 ]. Liquid chromatography combined with tandem mass spectrometry (LC
chromatography–tandem mass spectrometry (LC–MS/MS). This method was successfully used in the pharmacokinetic studies of supinoxin in rats and may be useful for the development of clinical data. Experimental Reagents and
