Fig. 5From: Protocol: a fast, comprehensive and reproducible one-step extraction method for the rapid preparation of polar and semi-polar metabolites, lipids, proteins, starch and cell wall polymers from a single sampleUPLC-MS base peak chromatograms of polar to semi-polar metabolites extracted from Arabidopsis rosette leaves. Relative abundances of eluted peaks versus retention time (min) are shown. The region of each eluted compound class is indicated according to its elution window either in positive or negative ionization modes. The number of detected compounds for every class is indicated in brackets (for details see Additional file 1: Table S4)Back to article page
