- ... Effects of extraction time and solvent polarity on antioxidant properties of Brassica oleracea leaves were optimized by response surface methodology using a central composite design. Five extraction times (12, 24, 36, 48 and 60h) and solvent polarities (dipole moment – hexane: 0.0, diethyl ether: 2.80, ethyl acetate: 4.40, methanol: 5.10 and water: 9.0D) were selected for optimization. Response su ...
