Dosaggio dei biofenoli degli oli vergini di oliva: idrossitirosolo e tirosolo, agliconi secoiridoidi, acidi secoiridoidi, lignani e flavonoidi

In this paper we propose an innovative method for extraction and quantitative analysis of biophenols minor polar compounds (BMP) in virgin olive oil. This method utilizes a SAX SPE (anionic exchange silica cartridge) for a one step concentration and purification of BMP. The proposed procedure is no time consuming and utilizes only a few millilitres of BMP recovery solvent. Data are compared to ones obtained with the same sample by classic liquid-liquid extraction and statistic data are tabulated for both procedures.
