Hyperoside or Isoquercitrin in Ethanolic Extracts from the Petals of Talipariti elatum S.W

Abstract

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 four solid samples extracted and isolated from the red petals of Talipariti elatum utilizing Soxhlet extraction with ethanol at 95 % during 20 hours. Three compounds were detected and two of them were identified as flavonoid glycosides while another one, is supposed to be and alkaloid with impair molecular weight. The compound with m/z of 464 after MS/MS analyses in both positive and negative ion mode is suggested to be Isoquercitrin. The mentioned compound has been identified in T. elatum for the first time in Cuban and Martinican flowers.
