“…In recent years, ILs-based extraction techniques were used for the extraction of phenolic compounds from plant materials [ 102 , 103 , 104 ]. However, the use of ILs-based extraction of phenolic compounds from the marine resources like seaweeds is scarce [ 86 , 105 ].…”

Natural phenolic compounds are important classes of plant, microorganism, and algal secondary metabolites. They have well-documented beneficial biological activities. The marine environment is less explored than other environments but have huge potential for the discovery of new unique compounds with potential applications in, e.g., food, cosmetics, and pharmaceutical industries. To survive in a very harsh and challenging environment, marine organisms like several seaweed (macroalgae) species produce and accumulate several secondary metabolites, including marine phenolics in the cells. Traditionally, these compounds were extracted from their sample matrix using organic solvents. This conventional extraction method had several drawbacks such as a long extraction time, low extraction yield, co-extraction of other compounds, and usage of a huge volume of one or more organic solvents, which consequently results in environmental pollution. To mitigate these drawbacks, newly emerging technologies, such as enzyme-assisted extraction (EAE), microwave-assisted extraction (MAE), ultrasound-assisted extraction (UAE), pressurized liquid extraction (PLE), and supercritical fluid extraction (SFE) have received huge interest from researchers around the world. Therefore, in this review, the most recent and emerging technologies are discussed for the extraction of marine phenolic compounds of interest for their antioxidant and other bioactivity in, e.g., cosmetic and food industry. Moreover, the opportunities and the bottleneck for upscaling of these technologies are also presented.

“…In addition, it was reported that the factors influencing the extraction ability are very complicated, hydrogen-bonding ability can be the main factor influencing the extraction considering the anions [31], π-π and n-π interactions also should not be omitted in view of imidazole ring-containing cations [32]. Although [C 4 mim]BF 4 was commonly used as the extractant in IL-UAE [18,[33][34][35], some research groups had reported that tetrafluoroborate-based ILs were not water-stable as they could undergo hydrolysis in aqueous solution [36,37] …”

Abstract:Background: Ionic liquids (ILs) are considered as green solvents, and widely applied for the extraction of various compounds. Methods: The present research focuses on the extraction of flavonoids from Apocynum venetum L. leaves by ultrasound-assisted extraction (UAE). Several major influencing factors were optimized. Then, an aqueous biphasic system (ABS) was applied for further isolation of flavonoids. Results: The flavonoids were mainly distributed in the top phase, while impurities were extracted to the bottom phase. The parameters influencing the extraction, namely type and concentration of salt, temperature, and pH, were studied in detail. Under optimized conditions (72.43% IL extract, 28.57% (NH 4 ) 2 SO 4 , 25˝C temperature, pH 4.5), the preconcentration factor and extraction efficiency were found to be 3.78% and 93.35%, respectively. Conclusions: This simple and efficient methodology is expected to see great use in the extraction and isolation of pharmaceutically active components from medicinal plant resources.

“…The results showed that high amounts of phenolics compounds were obtained in the first minute of extraction and longer time did not effect on amount of extraction. Also in the other research plan Row et al performed extraction of phenolic compounds from Laminaria japonica Aresch with three kinds of 1-alkyl-3-methylimidazolium with different cations and anions [25]. The results showed that, the characteristics of both anions and cations have remarkable effects on the extraction efficiency.…”

Phenolic derivatives are one of the most important compounds that were found in secondary metabolites in plants. According to their various applications in agriculture, food, chemical and pharmaceutical industries, interests in reviewing different procedures of extraction of these compounds from plants have increased. In this chapter, we would like to have an overview on the extraction procedures that have been used in isolating phenolic compounds from plants until this time, including liquid-liquid extraction (LLE), ultrasound-assisted extraction (UAE), microwave-assisted extraction (MAE) and supercritical fluid extraction (SFE). In the following, advantages and disadvantages of these techniques and methods will be discussed and explained. In addition, in the last part of this chapter, various methods for purification and identification of phenolic compounds will be presented.
