“…Some DES ingredients might also be affected by the pH themselves, changing their polarity or general behavior, with beneficial or undesirable results. The form of the target (a result of the pH) may completely change the design of the extraction, given that a solvent with a completely different polarity would be extracted by a different DES than originally planned [50,51].…”

The present review article attempts to summarize the use of deep eutectic solvents in the extraction of flavonoids, one of the most important classes of plant secondary metabolites. All of the applications reviewed have reported success in isolation and extraction of the target compounds; competitive, if not superior, extraction rates compared with conventional solvents; and satisfactory behavior of the extract in the latter applications (such as direct analysis, synthesis, or catalysis), wherever attempted.

“…In recent years, deep eutectic solvents (DESs) have been regarded as a green solvent alternative to toxic organic solvents due to their low cost, easy preparation, nontoxic, biodegradable, and eco‐friendly properties [11–13], which have been widely used to prepare and extract various natural bioactive ingredients from plants [14,15]. One of the attractive features of these novel solvents is the possibility to generate a huge number of eutectic mixtures with different physicochemical properties by simply changing one or both components [16,17].…”

Taxanes are natural anticancer constituents, and the sample preparation from matrix normally depends on organochlorine solvents. In this study, green and natural menthol-based aqueous deep eutectic solvent was synthesized and used for sample preparation for taxanes. Five key parameters were optimized and the optimal preparation conditions were as follows: menthol/1-propanol ratio 1:1 (mol/mol), solid-liquid ratio 1:30 g/mL, extraction time 30 min, ultrasonic power 250 W, and water content 80%. Under the above conditions, the total extraction efficiency of seven main taxanes was 1.25-to 1.44-fold to the conventional methods. In addition, a high-performance liquid chromatography method with C 18 column was established for quantitation of seven main taxanes in <25 min, which had excellent linearity (R 2 > 0.9986), precision (relative standard deviation < 3.00%), repeatability (relative standard deviation < 3.69%), and recovery (90.26-109.00%). This method performed the extraction, and enrichment processes simultaneously, and it had advantages such as high extraction efficiency, simple operation, low cost, and eco-friendliness. This work indicated that the natural menthol-based deep eutectic solvent aqueous could be an excellent alternative to the sample preparation from Taxus or other plants.

“…The charge delocalization occurring through hydrogen bonding between, for instance a halide ion and the hydrogen-donor moiety, is responsible for the decrease in the melting point of the mixture, in relation to the melting points of the individual components [ 19 , 20 ]. Since 2001, many scientists around the globe pursed the utilization of DESs and published a variety of studies [ 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ].…”
