Relatively few studies have been focused so far on magnesium–isotope fractionation during plant growth, element uptake from soil, root-to-leaves transport and chlorophylls biosynthesis. In this work, maize garden cress were hydroponically grown in identical conditions order to examine if the carbon fixation pathway (C4, C3, respectively) might impact Mg-isotope chlorophyll-a. The pigment was purified plants extracts by preparative reversed phase chromatography, its identity confirmed...
Abstract Objective The goal of this work was to set up a high throughput procedure for the determination fatty acid methyl esters ( FAME s) in cosmetic castor oils using flow injection–electrospray ionization–high‐resolution mass spectrometry, and demonstrate need such analysis quality control purposes. Methods sample aliquot mixed with isooctane:chloroform (1:1) submitted transesterification; obtained s were appropriately diluted water:isopropanol:acetonitrile (20:50:30) addition sodium...
