Recommanded Product: 6381-59-5In 2017 ,《Using Ionic Liquids To Tune the Performance of Aqueous Biphasic Systems Based on Pluronic L-35 for the Purification of Naringin and Rutin》 was published in ACS Sustainable Chemistry & Engineering. The article was written by e Silva, Francisca A.; Carmo, Rui M. C.; Fernandes, Andreia P. M.; Kholany, Mariam; Coutinho, Joao A. P.; Ventura, Sonia P. M.. The article contains the following contents:
Aqueous biphasic systems (ABS) based on Pluronic L-35, a (EO)x-(PO)y-(EO)x triblock copolymer, were determined and applied in the separation of two structurally similar flavonoids (naringin and rutin). Two sets of phase formers were paired with Pluronic L-35, one comprising conventional salts/buffer and other including cholinium-based ionic liquids (ILs). It is shown that while the conventional salts induce an unbalanced and strong salting out leading to complete extraction of flavonoids to the same phase in most of the cases (84.7 ± 0.6% ≤ RNAR ≤ 100% and 53.2 ± 0.5% ≤ RRUT ≤ 99.7 ± 0.1% with selectivities ranging from 1 to 11.8), the cholinium-based ILs provide an enhanced extractive performance. Indeed, these novel cholinium ILs/Pluronic L-35-based ABS allowed the manipulation of the affinity of both naringin and rutin to opposite phases, thus yielding a selective separation The best results were achieved for the system using [Ch][Bic] as phase former (RNAR = 89.6 ± 0.3 and RRUT = 32 ± 2 with a selectivity of 18.9). An integrated approach based on the sequential implementation of Na2SO4/Pluronic L-35- (step 1) and [Ch][Bic]/Pluronic L-35-based (step 2) ABS was designed to purify the flavonoids from a complex synthetic mixture simulating natural extracts Remarkably, glucose (the main contaminant) was removed during step 1 with an extraction efficiency of 60 ± 4% to the Na2SO4-rich phase, while step 2 has enabled the efficient separation of naringin from rutin.
