In this study, plasma samples were collected from 28 health volunteers and 66 lung cancer patients. Ultraperformance HILIC/Q-TOF MS-based metabonomic techniques were employed to compare the highly polar metabolites (HPMs) in the plasma of patients with lung cancer and those in the plasma of healthy volunteers. High separation efficiency and good repeatability of the HILIC/Q-TOF MS method were observed...
Highly polar metabolites are abundant in human plasma. Analysis of these compounds by standard reverse-phase chromatography is difficult. Highly polar metabolites were extracted by a two-step method. They were analyzed by ultra-performance hydrophilic interaction chromatography (HILIC) coupled to quadrupole-time of flight mass spectrometer detection technology. The middle and low polar fraction were...
