摘要
The qualitative and quantitative research on glycolipids compounds was analyzed by means of the flight time ultra-high performance liquid chromatography tandem mass spectrometry(UPLC-Q-TOF-MS) technology.The mass spectrometry was performed in reflective time-of-flight using electron spraying ionization.The components in monoglycosyldiglycerides(MGDG) and diglycosyldiglycerides(DGDG) were determined in positive ion mode,and the sulfoquinovosyl diacylglycerol(SQDG) were analyzed in negative ion mode.The results showed that each component in golycolipids can be separated effectively with gradient elution in the BEH C18 column.The proportion of each components accounts for total glycolipids can be determined by using degree elution.
