UPLC-MSE Profiling of Phytoplankton Metabolites: Application to the Identification of Pigments and Structural Analysis of Metabolites in Porphyridium purpureum

Autor: Camille Juin, Antoine Bonnet, Elodie Nicolau, Jean-Baptiste Bérard, Romain Devillers, Valérie Thiéry, Jean-Paul Cadoret, Laurent Picot

Publikováno v: Marine Drugs, Vol 13, Iss 4, Pp 2541-2558 (2015)

A fast and high-resolution UPLC-MSE analysis was used to identify phytoplankton pigments in an ethanol extract of Porphyridium purpureum (Pp) devoid of phycobiliproteins. In a first step, 22 standard pigments were analyzed by UPLC-MSE to build a data
