Total biflavonoids extraction from Selaginella chaetoloma utilizing ultrasound-assisted deep eutectic solvent: Optimization of conditions, extraction mechanism, and biological activity in vitro

Are Bio-Based Solvents Helpful in Controlling Environmental Pollution? Insights from The BRICS Countries

“…The results demonstrated that the combination of proline-lactic acid extracts robusta flavone and amentoflavone perfectly. The DESs-UAE approach achieved a high extraction rate, outperforming conventional techniques under optimised conditions and consuming less time [42].…”

“…Thirty various DESs consisting of proline, lactic acid, betaine and choline chloride as HBDs with different HBAs such as malic acid, urea, sorbitol and glucose were synthesised by Liu et al [42] in order to extract robusta flavone and amentoflavone from S. uncinata. Additionally, to improve efficiency and reduce energy wastage and time consumption, the DESs-UAE based on ultrasound extraction techniques (DESs-UAE) were suggested over conventional extraction methods such as percolation, reflux and maceration.…”

Green and highly effective extraction of bioactive flavonoids from Fructus aurantii employing deep eutectic solvents-based ultrasonic-assisted extraction protocol

“…Deep eutectic solvents (DESs), a breakthrough environmentally benign solvent that has the potential to replace organic solvents, have been receiving considerable attention in recent years [11] , [12] , [13] . Usually, hydrogen bond donors (HBDs) and acceptors (HBAs) are combined and heated in the proper mole ratio to create DESs, which then react based on hydrogen bond interaction [11] , [12] , [13] , [14] , [15] . In comparison with conventional organic solvents, DESs are not only non-toxicity, inexpensive in cost, environmental friendliness, biodegradable, nonflammable and stable, but they also have a series of benefits including quick and easy synthesis, availability and high-efficiency [16] , [17] , [18] , [19] , [20] , [21] , [22] .…”

Deep eutectic solvent extraction of myricetin and antioxidant properties

“…Compared to conventional extraction methods, the extraction efficiency of this method increased by 10.74%. Wang et al , 19 used ultrasonic-assisted extraction (DES-UAE) with deep eutectic solvent to extract the Selaginella chaetoloma total biflavonoids (SCTB). Tetrapropylamonium bromide-1,4-butanediol (Tpr-But) was used as the extractant for optimisation.…”
