Abstract
Deep eutectic solvents (DESs) have emerged as one of the most promising alternatives to conventional organic solvents in the 21st century. Due to their low toxicity, biodegradability, and simple preparation, DESs are increasingly recognised as sustainable and eco-friendly solvents. In the field of natural product research, they offer unique advantages, such as tunable polarity, strong solubilisation capacity, and the ability to selectively extract bioactive compounds from complex plant and algal matrices. Compared to traditional extraction techniques, DES-based methods minimise environmental impacts, reduce energy consumption, and often enhance extraction yields and selectivity. Our research group focuses on the extraction of bioactive sulphated polysaccharides and phenolic compounds from marine seaweeds. Several novel DESs were prepared using choline chloride in combination with other environmentally benign components. The molecular interactions within these newly synthesised DESs were characterised by Fourier-transform infrared (FTIR) and nuclear magnetic resonance (NMR) spectroscopy, while their physical properties (density, viscosity, and thermal behaviour) were systematically evaluated. Our multidisciplinary approach integrates green chemistry with natural products chemistry to develop sustainable extraction strategies from Egyptian marine resources. This work contributes to advancing Egypt’s scientific and technological capacity and aligns with the nation’s Vision 2030 for sustainable development.
