Supercritical CO2 (scCO2)extraction, with methanol as modifier, was applied to the determination of ubiquinones and menaquinones in activated sludge. Four ubiquinones and 12 menaquinones species were identified based on retention time and UV spectrum in 0.1 g dried activated sludge. The optimum extraction conditions were at a pressure of 25MPa, a temperature of 55 .C, and 10
