EXTRACCIÓN ASISTIDA POR BAÑO DE ULTRASONIDOS Y CARACTERIZACIÓN QUÍMICA POR HPLC-ESI-UV-MS/MS

Resumen

A sample of petals from the flowers of Talipariti elatum (Sw.) dried at shadow at room temperature
was extracted with ethanol 95 % using for the first time an Ultrasound Bath after 3 hours. Liquid
chromatography (LC) coupled with UV detection and electrospray ionization (ESI) tandem mass
spectrometry (MS/MS) was used for the generation of chemical fingerprints and the identification of phenolic compounds in Blue Mahoe from Martinica Island. Fifty seventh compounds were detected by HPLC and among them, 21 of these detected by MS after base peak filtration. The structures of eleven compounds found in this hydroethanolic extract were suggested mainly by MS data conjugated with the UV spectra, reference compounds and available mass spectra data in literature. To the best of our knowledge, with exception of gossypetin-3’-O-glucoside found in the petals of the flowers, nothing has been published about the chemical composition of T. elatum in Martinica.
