Gastroprotective activity of Parastrephia quadrangularis (Meyen), cabrera from the atacama desert
High-resolution mass spectrometry is currently used to determine the mass of biologically active compounds in plants and UHPLC-Orbitrap is a relatively new technology that allows fast fingerprinting and metabolomics analysis. In this work, several phenolic compounds including eleven phenolic acid...

UHPLC high resolution orbitrap metabolomic fingerprinting of the unique species Ophryosporus triangularis meyen from the atacama desert, Northern Chile
UHPLC/ESI/MS identification of organic compounds is the first step in the majority of screening techniques for the characterization of biologically active metabolites in natural sources. This paper describes a method for the fast identification and characterisation of secondary metabolites in Lep...
