Chemical profiling and quantification of ShenKang injection, a systematic quality control strategy using ultra high performance liquid chromatography with Q Exactive hybrid quadrupole orbitrap high‐resolution accurate mass spectrometry

ShenKang injection is traditional Chinese medicine used to treat chronic renal failure in China. It is a compound preparation that consists of four herbs: Rhubarb, Salvia miltiorrhiza, Safflower and Radix Astragali . We developed an ultra high pressure liquid chromatography coupled with Q Exactive hybrid quadrupole‐orbitrap high resolution accurate mass spectrometry tandem mass spectrometry method to analyze its chemical compositions, and a...
