Mesembryanthemum edule (Aizoaceae family) is an edible halophyte widely used as a food ingredient and in traditional medicine. This study was intended to characterize the phenolic compounds of M. edule fresh and stone stems. The approach consisted to establish the phenolic composition through LC-DAD-ESI/MS consisted of an Acquity UPLC (Waters, Milford, MA) coupled with DAD and a Brucker Daltonics Ion trap mass spectrophotometer. The UPLC analysis revealed that the main phenolic compounds were catechin, epicatechin and procyanidin (4.9% yields) in the fresh stems, while catechin,epicatechin, procyanidin and propelargonidins (5.06% yields) were the most abundant phenolics in the stone stems.
