Phenolic profiles of Portuguese olive fruits (Olea europaea L.): influence of c...
Vinha, A.F.; Ferreres, F.; Silva, B.M.; Valentão, P.; Gonçalves, Artur; Pereira, J.A.; Oliveira, M.B.P.P.; Seabra, R.M.; Andrade, P.B.The phenolic compounds present in 29 samples of olive fruits were analysed by reversed-phase HPLC/DAD and/or HPLC-DAD/ ESI-MS/MS. All samples were collected during the normal picking period for olive oil production, in north and central Portugal, and were obtained from 18 different olive cultivars. Two different extraction methods were necessary for the complete quantification of phenolic compounds, a methanoli...
Development and evaluation of an HPLC/DAD method for the analysis of phenolic c...
Vinha, A.F.; Silva, B.M.; Andrade, P.B.; Seabra, R.M.; Pereira, J.A.; Oliveira, M.B.P.P.A new HPLC/DAD methodology for separating nine phenolic compounds is described. This methodology is applied to the definition of qualitative and quantitative profiles of three Portuguese olive fruit cultivars (Cobrançosa, Madural and Verdeal). Two different extraction methods were needed for the complete definition of their profiles, one of them including a Sep-pack C18 cleaning step. The chromatographic separa...
