Phytochemical and antioxidant comparison of <i>Quercus ilex</i> and <i>Quercus robur</i> acorn extracts obtained by matrix solid-phase dispersion.

ABSTRACT: Oak (Quercus spp.) acorns are used in animal feed and in the treatment of specific diseases due to their nutritional value and high content of bioactive compounds. The aim of the present work is to investigate and compare polyphenolic compounds and the antioxidant activity of Quercus ilex and Quercus robur acorn extracts. This is performed using the matrix solid-phase dispersion (MSPD) extraction process, in an environmentally friendly way with different generally recognised as safe (GRAS) solvents. The GRAS solvents considered were an alcohol, a ketone, an ester and a glycol. Total polyphenolic content (TPC) and antioxidant activity (DPPH and ABTS scavenging test) were determined spectrophotometrically. The different antioxidant data obtained by two approaches are dis
