Establishment of retention index library on gas chromatography-mass spectrometry for nontargeted metabolite profiling approach

Abstract

The retention indices of metabolites expected to be in rice have been established with gas chromatography-mass spectrometry (GC-MS) after derivatization. Total 187 metabolites (59 lipids and 128 polar metabolites) including fatty acids, hydrocarbons, alcohols, steroids, sugars, sugar alcohols, organic acids, amino acids, amines, and amides were analyzed using GCMS and their retention indices were calculated. These retention indices are expected to be used for the identification of various metabolites in many types of crops. © 2013 The Korean Society for Applied Biological Chemistry.
