Aplicação de LC-SPE/NMR na rápida identificação de compostos orgânicos em fitoterápico

Le résumé fourni par la source

This article describes the analysis of the chemical profile of a phytotherapeutic supplement of \nIlex paraguariensis that was rapidly conducted by using the LC-SPE/NMR hyphenated technique providing \nthe rapid separation and identification of eight organic compounds in a single experiment. Therefore, bench \nisolation methods were not necessary. The high selectivity achieved in the chromatographic separation \ncombined with adequate retention by SPE and the application of cryogenic technology of high magnetic field \nNMR (14.1 Tesla) allowed to reach conclusive data on the structure of the substances found, thus the use of \nmass spectrometry was unnecessary.
