Abstract

At present, only a few papers reported in literature are focused on the evaluation of the phenolic content of Solid Olive Residues (SOR).This work is a continuation of a preliminary study1 focused on the chemical characterisation of verbascoside analogues from SOR of Coratina, a wide spread cv in the south of Italy. Many interesting activities attributed to this class of compounds are reported in literature, in particular they act as antioxidant, neurosedative, anti-inflammatory 2, antiviral3-4 and anticancer agents. Thus, the possibility to recover an extract enriched with these bioactive molecules, obtained from a low cost and widely diffused by-product in the Mediterranean basin, was evaluated. The research was developed in four steps: 1) a selection of the richest matrix, 2) an optimisation of all the extraction procedures to obtain a raw extract enriched in phenyl propanoids; 3) a fractionation phase by a treatment with Sephadex LH-20 and a purification of the target molecules using semi preparative HPLC; 4) the structural elucidation of the isolated compounds by HPLC/DAD/MS analysis and 1D-2D- homo and hetero-correlated NMR experiments.
