| Abstract: | Partitioning of anthocyanins contained in the crude extract ofSyzygium cuminifruit was investigated in aqueous two-phase systems (ATPS) made up of isopropa-nol and Na2SO4/(NH4)2SO4.Na2SO4induced ATPS formation more effectivelythan (NH4)2SO4. The increase in temperature enhanced phase separation in the(NH4)2SO4ATPS, while the opposite occurred in the Na2SO4ATPS. The higherthe overall mixture concentration or temperature, the higher the values of tie-linelength and slope. In all systems and conditions, anthocyanins preferentially parti-tioned to the top phase. The partition coefficient and theoretical recovery yield inthe top phase varied in the ranges 1.14–1.77 and 53.31–63.87 % in the (NH4)2SO4ATPS, and in the ranges 1.94–21.50 and 65.90–95.55 % in the Na2SO4ATPS. |
