Laser Desorption Low-Temperature Plasma Mass Spectrometry Imaging (LD-LTP MSI) of San Pedro cactus

<p>Mass spectrometry imaging (MSI) data set in imzML format, obtained from San Pedro cactus (<em>Echinopsis pachanoi</em>) cross-section using&nbsp;Laser Desorption Low-Temperature Plasma ionization. Mapping the ion that corresponds to mescaline shows a star-like distribution of this interesting&nbsp;alkaloid.</p> <p>The experiment is described in:</p> <p>Elucidating the Distribution of Plant Metabolites from Native Tissues with Laser Desorption Low-Temperature Plasma Mass Spectrometry Imaging,&nbsp;Abigail Moreno-Pedraza,&nbsp;Ignacio Rosas-Rom&aacute;n,&nbsp;Nancy Shyrley Garcia-Rojas,&nbsp;H&eacute;ctor Guill&eacute;n-Alonso,&nbsp;Cesar&eacute; Ovando-V&aacute;zquez,&nbsp;David D&iacute;az-Ram&iacute;rez,&nbsp;Jessica Cuevas-Contreras,&nbsp;Fredd Vergara,&nbsp;Nayelli Marsch-Mart&iacute;nez,&nbsp;Jorge Molina-Torres, and&nbsp;Robert Winkler,&nbsp;Analytical Chemistry&nbsp;<strong>2019</strong>&nbsp;<em>91</em>&nbsp;(4), 2734-2743</p> <p>DOI: 10.1021/acs.analchem.8b04406</p> <p>&nbsp;</p>
