    Annotation Ultrasound-assisted micellar extraction of phenolic antioxidants from spices has been developed for the first time. The effect of the surfactant nature and its concentration on the extraction efficiency has been evaluated. Electrogenerated hexacyanoferrate(III) ions have been used as coulometric titrants owing to their selectivity towards phenolic antioxidants. The best recovery of phenolic antioxidants has been obtained using nonionic 0.1 mol L-1 Brij? 35 micellar medium by single extraction for 10 min with ultrasound treatment. The spice/extractant ratio that provided maximum recovery of phenolic antioxidants was found for 20 spices. Comparisons with ethanolic and methanolic extracts have been performed. Micellar extracts show significantly higher recovery of phenolic antioxidants. The antioxidant properties of the spices' micellar extracts have been estimated using total antioxidant capacity (TAC), ferric reducing power (FRP) and ceric reducing/antioxidant capacity (CRAC).
