“…Then an increase in the amount of ionic liquid causes an increase in the volume of the upper phase and a decrease in the volume of the lower phase. Therefore, the extraction efficiency begins to decrease [24]. The highest recovery was obtained with 200 µL of ionic liquid for three MILs.…”

An aqueous two-phase extraction system was constituted using magnetic ionic liquid-nonionic surfactant for phenolic acids and the developed method was applied to apple, grape, pear, and banana samples. Ionic liquids based on imidazolium containing butyl, allyl, and benzyl groups were used for extraction. The parameters influencing the extraction efficiency such as volume of ionic liquids, type and amount of surfactant and salt, ultrasound extraction time, temperature, and sample pH were optimized. The extraction efficiencies of ionic liquids were compared for phenolic acids under optimized conditions. Limits of detection and limits of quantification were in the range of 1.34-1.56 µg L −1 and 4.33-4.68 µg L −1 , respectively. The interday and intraday precision (RSD%) for the phenolic acids at 5 and 25 µg L −1 were in the range of 4.48%-5.69% and 3.02%-4.51%, respectively. The spiked recoveries of phenolic acids were between 70.78% and 99.97% in real samples.

“…MILs have found some applications in the plant field, in particular in the extraction of sinomenine from Sinomenium acutum (Thunb.) Rehder & E.H.Wilson [17] and in the extraction, adopting an ABS approach, of berberine from the rhizome of Coptis spp [18]. They also have been used for the isolation of DNA from Arabidopsis thaliana (L.) Heynh.…”

Analyses in the plant field have to cover a wide range of topics, starting from metabolomics to the quali-quantitative determination of a single or a class of metabolites, often dealing with very complex matrices. The development of an appropriate sample preparation method is fundamental to obtain complete information, because downstream analyses will detect only the metabolites previously extracted. The choice of the proper extraction phase is therefore of utmost importance and the most critical parameter to be considered. Although most of the studies on plants still mainly adopt traditional extraction techniques, a wide number of new phases with improved features in terms of tunability, selectivity and, most important, sustainability have been developed in the past decades and applied to the study of natural products. This review provides an overview of the new extraction phases developed and adopted for the study of plant endogenous and exogenous metabolites.

“…However, due to their high affinity for water, these ILs are usually studied in combination with polyethylene glycol (PEG) or polypropylene glycol (PPG) to form ABS [ 23 , 24 , 25 , 26 , 27 ]. On the other hand, there is only a limited number of reports about choline-based ILs applied to develop ABS with inorganic or organic salts [ 28 , 29 , 30 , 31 ].…”

Phase Behavior of Aqueous Biphasic Systems with Choline Alkanoate Ionic Liquids and Phosphate Solutions: The Influence of pH

2021

Aqueous biphasic systems (ABS) composed of the choline alkanoate ionic liquids (ILs) choline acetate [Cho][OAc], choline propanoate [Cho][Pro], choline butyrate [Cho][But], and choline hexanoate [Cho][Hex], mixed with K3PO4 solutions at pH 7.2 and 14.5, were prepared and their phase diagrams were compared. The ability to form ABS with alkaline K3PO4 solutions decreased in the order [Cho][OAc] ≈ [Cho][Pro] > [Cho][But] > [Cho][Hex], while with neutral K3PO4 solutions, [Cho][OAc] could not form an ABS, and the other three ILs performed similarly. All of the biphasic regions of the ABS decreased with the increase in pH. 1H-NMR data indicated anion exchange between phases in ABS at neutral pH. The ABS at neutral pH were evaluated to extract the triazine herbicides simazine, cyanazine, and atrazine, and the ABS formed by [Cho][Pro] and the pH 7.2 K3PO4 solution has shown extraction recoveries higher than 90%.
