“…17 Additionally, ionic liquids in combination with more efficient extraction processes, such as microwave or ultrasound, have been successfully employed to extract various types of natural products including alkaloids, phenolic derivatives, terpenes and other metabolites. [18][19][20][21][22][23][24][25][26][27][28][29] Due to the high viscosity of the ionic liquids, usually they are used dissolved in water, which lowers the cost of the process. Finally, it is noteworthy that ionic liquids are compounds that absorb microwave very efficiently, making them excellent solvents when this technology is required.…”

This work reports the application of an ionic liquid (1-butyl-3-methylimidazolium bromide, BMImBr) in the microwave assisted extraction (MAE) of metabolites from fruits of Schinus terebinthifolius. Dried fruits were individually extracted using BMImBr:H 2 O 1:1, v/v (experiment 1) and pure H 2 O (experiment 2) by MAE (10 min at 60 °C). After partition using EtOAc, the yield to experiment 1 was about 23% while to experiment 2 was 0.1%. The EtOAc fraction obtained from experiment 1 was purified by chromatographic methods to afford 3-oxotirucalla-7,24Z-dien-27-oic acid, 3a-hydroxytirucalla-7,24Z-dien-27-oic acid, 3a-acetoxytirucalla-7,24Z-dien-27-oic acid, gallic acid, and ethyl gallate, being the first occurrence of the third compound as natural product. Cytotoxic activity was evaluated in vitro against cancer cell lines (A2058, HeLa, SiHa, HCT, SKBR-3, U87, and B16F2Nex2), being 3a-acetoxytirucalla-7,24Z-dien-27-oic acid the more active metabolite with IC 50 ranging from 10.9 ± 1.3 to 17.3 ± 1.4 µg mL -1 , lower than that determined to positive control cisplatin.

Ionic liquids (ILs) have been widely examined as solvents, additives, or catalysts in a variety of applications including organic catalysis [ 1 -5 ], inorganic and materials synthesis [ 6 ], biocatalysis [ 7 -12 ], electrochemistry [ 13 ], pharmaceutical chemistry [ 14 ], polymerization [ 15 , 16 ], and engineering fl uids [ 17 -19 ]. The physicochemical properties of ILs are tunable through a careful selection of a variety of different cations and anions and a rational combination of ion pairs. More interestingly, cations and/or anions can be further functionalized to form so-called task-specifi c ionic liquids (TSILs). The notion of TSILs carrying specifi c functionality tailored for particular applications has proven visionary, and a variety of different functional groups have been grafted onto ILs [ 20 -22 ]. In particular, there is an exponential growth in constructing new TSILs as electrolytes for electrochemical applications. This chapter focuses on a critical discussion of some major types of TSILs and their electrochemical properties and applications. Ether/Thioether-and Hydroxyl/Thiol-Functionalized ILs General Physical PropertiesOur recent review has captured some key physical properties of ether-and alcoholfunctionalized ILs [ 22 ]. The inclusion of alkyloxy or alkyloxyalkyl groups in ILs often lowers the melting points ( T m ) [ 23 -26 ]. Additionally, the lowering of the
