Abstract
was the most efficient. The washing of coca leaves with the organic solvents (acetonitrile, methanol, toluene, and dichloromethane) tested did not improve the performance of the ionization process. Finally, a tissue section, 50 μm thick, was used to study the inner part of the leaf tissue, where alkaloids and flavonoid molecules were detected.
