Extraction assisted by Ultrasound Bath and Chemical Characterization by 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.
