Comprehensive evaluation on tailor-made deep eutectic solvents (DESs) in extracting tea saponins from seed pomace of Camellia oleifera Abel

Quinoa (Chenopodium quinoa Willd) Bran Saponins Alleviate Hyperuricemia and Inhibit Renal Injury by Regulating the PI3K/AKT/NFκB Signaling Pathway and Uric Acid Transport

“…42 The stretching vibration at 950−700 cm −1 was caused by the sugar in the carbohydrate or aglycone ring skeleton. 43 Identification of Saponins in Quinoa Bran by UHPLC−MS. By integrating the ion flow spectrum data in Figure S1, 11 saponins were screened in the QBS4 fraction of quinoa bran (Table 1), and their chemical structures are shown in Figure S2A The remaining six saponins (compounds 5−7 and 9−11, Table 1) were tetracyclic triterpene saponins representing <23% of the total, with individual compounds representing as much as 5.25 ± 0.43% (momordicoside G) to as low as 0.39 ± 0.09% (ginsenoside Rb1) of total saponins.…”

“…The strong response value at 1074 cm –1 was the absorption peak of the C–O–C vibration, indicating that the stretching vibration might be caused by the bond linking the glycosides and aglycones . The stretching vibration at 950–700 cm –1 was caused by the sugar in the carbohydrate or aglycone ring skeleton …”

Ultrasound-assisted deep eutectic solvents extraction of glabridin and isoliquiritigenin from Glycyrrhiza glabra: Optimization, extraction mechanism and in vitro bioactivities

“…3 A, the extraction yields of GLA and ISL changed irregularly with the change of molar ratio. Different molar ratios of HBA and HBD can change the physicochemical properties of the DES such as pH, polarity, viscosity, and density, which affect the interactions between the target products and DES [34] . A maximize extraction yield was obtained when the molar ratio of CHLa was 1:1, indicating that this molar ratio was most suitable for the simultaneous extraction of GLA and ISL.…”

Utilization of natural deep eutectic solvents and ultrasound-assisted extraction as green extraction technique for the recovery of bioactive compounds from date palm (Phoenix dactylifera L.) seeds: An investigation into optimization of process parameters

“…3a .The improvement in the recovery of the bioactive compounds when utilizing UAE is generally due to the acoustic cavitation which generate bubbles and cause a rise in pressure and temperature as the bubbles collapse there is a disruption in the date seed cell wall matrix permitting the release of the bioactive compounds [8] The effect of using UAE includes cell wall disruption, facilitate solvent penetration and allow the release of bioactive compounds effectively [8] , [51] . Also, the ability of NADES to extract bioactive compounds is related to its physicochemical characteristics such as viscosity, pH, polarity, and the type of interactions between the hydrogen bond donor and acceptors [52] . The NADES utilized in the study are the ChCl-based NADESs comprising of carboxylic acid-based HBD, sugar-based, and polyalcohol-based HBD as presented in Table 1 .…”
