Article Abstract
A novel approach for extraction and purification of the anthocyanins from was developed by microwave-assisted deep eutectic solvent extraction (MAE-DES) coupled to macroporous resin separation (MRS). Citric acid-based DES as the extractant was screened and characterized from 13 synthesized deep eutectic solvents due to the excellent performance. Through RSM optimization of MAE-DES process, the anthocyanin yield reached 6.442 ± 0.135 mg/g, demonstrating that MAE-DES significantly superior to that of conventional methods. With AB-8 MRS purification, the anthocyanin purity was increased by 63-fold. By UHPLC-Q-TOF-MS/MS, the anthocyanins obtained from were dominantly composed of pelargonins. Based on composition analysis, pH differential method was first modified by introducing weighting factors, avoiding serious underestimation of the anthocyanins content in . MAE-DES and the modified spectrophotometry were successfully applied for assessment of anthocyanin extraction and sample drying methods, providing an efficient alternative to development and application of the anthocyanins from .

This study aimed to develop an efficient green ultrasound-assisted extraction (UAE) method for naringin (Nar) from Exocarpium Citri Grandis (ECG) using a glycerol-based ternary natural deep eutectic solvent (NADES) and explore its biofunctional relevance. After screening and single-factor optimization, the optimal NADES was identified as glycerol:malic acid:propanedioic acid (1:1:2 M ratio, 30 % water content). Extraction conditions (liquid-solid ratio, temperature, time) were optimized via response surface methodology (RSM) and an artificial neural network-genetic algorithm (ANN-GA), with ANN-GA demonstrating superior predictive capability.

Multiple stretchable gels with conductivity have been thoroughly prepared in diverse solvents historically to modulate their superlative properties in a multitude of applications, such as soft robotics, wearable devices, and e-skins. Eutectogels are considered as an emerging class of gels that combine the best features of both hydrogels and organogels, including environmental friendliness, thermal stability and customizable nature. Eutectogels, composed of deep eutectic solvents (DES) immobilized within different matrices, not only inherit the merits of DES, but also show some additional properties derived from the special structure and compositions, which are conducive to development potential.

Nowadays, the recovery of valuable metals from waste mobile phone printed circuit boards (WMPCBs) has attracted significant attention from researchers due to their economic potential. However, improper recycling poses serious risks to both human health and the environment. This study introduces, for the first time, a deep eutectic solvent (DES) as a novel, green, and highly selective carrier within an emulsion liquid membrane (ELM) system for the recovery of gold (Au) from WMPCBs.

Polymerizable deep eutectic solvents (PDES) have recently emerged as a class of solvent-free ionically conductive elastomers and are considered among the most feasible candidates for next-generation ionotronic devices. However, the fundamental challenge persists in synergistically combining high mechanical strength, robust adhesion, reliable self-healing capacity, and effective antimicrobial performance within a unified material system capable of fulfilling the rigorous operational demands of next-generation ionotronic devices across multifunctional applications. Inspired by the hierarchical structure of spider silk, HCAG eutectogels composed of acrylic acid (AA), 2-hydroxyethyl acrylate (HEA), and choline chloride (ChCl) were successfully synthesized via a one-step photopolymerization method.

Effective removal of trace heavy metal ions from aqueous bodies is a pressing problem and requires significant improvement in the area of absorbent material in terms of removal efficiency and sustainability. We propose an efficient strategy to enhance the adsorption efficiency of carbon nanotubes (CNTs) by growing dendrimers on their surface. First, CNTs were pre-functionalized with maleic acid (MA) via Diels-Alder reaction in presence of a deep eutectic solvent under ultrasonication.
