Optimization and kinetic study of ultrasound assisted deep eutectic solvent based extraction: A greener route for extraction of curcuminoids from Curcuma longa

Study the impact of ultra-sonication and pulsed electric field on the quality of wheat plantlet juice through FTIR and SERS

“…The rise of TPC and TFC ultimately increases antioxidant attributes beneficial for health [29] . During the US, the increase in TPC might be due to the discharge of the bound form of phenolics through the cell membranes ruptured due to the cavitation process [30] , [31] . A similar increment in TPC was also recorded in PEF applied apricot juice [32] and the US-treated sugarcane juice [6] .…”

Microwave-assisted Natural Deep Eutectic Solvents Pretreatment Followed by Hydrodistillation Coupled with GC-MS for Analysis of Essential Oil from Turmeric (<i>Curcuma longa</i> L.)

“…Additionally, pretreatment is indispensable to overcome the natural recalcitrance of plant cell walls 13,14 , and enhance the release of intracellular compounds. Recently, deep eutectic solvents DESs have emerged as a class of novel green fluids, which are composed of hydrogen bond donors HBD and acceptors HBA 15,16 to form a new solvent mixture with lower melting point than those of the individual components 17 . They show many favorable properties including negligible vapor pressure, nonflammability, low toxicity, biocompatibility and the possibility of being made from renewable materials; at the same time, their physico-chemical properties can be tuned by modifying the HBA/HBD structures or by changing the molar ratio of these components 18 .…”

Latest Insights on Novel Deep Eutectic Solvents (DES) for Sustainable Extraction of Phenolic Compounds from Natural Sources

“…Patil et al [ 76 ] described a DES-based UAE of curcuminoids from turmeric. Herein, nine ChCl-based DESs were prepared and screened for curcuminoids extraction using glycerol (1:2), ethylene glycol (1:1), 1,4-butanediol (1:3), lactic acid (1:1), malic acid (1:1), citric acid (2:1), xylose (1:1), glucose (2:1), and fructose (2:1) as the HBDs.…”
