“…AC made a better contribution compared with the other two. The most likely reason is that the high water contents or extraction times might affect the force between polysaccharides and DES (Meng et al 2023).…”

Effects of the different types of deep eutectic-like solvents (DESs), molar ratio, water content, extraction temperature, extraction time, and ratio of liquid to solid were studied relative to the yield of Leonurus residue crude polysaccharide (LRCP). Extraction amounts of LRCP were determined. The extraction process parameters were optimized by response surface methodology, and an optimal extraction process was achieved. The results showed that DESs comprising choline chloride and ethylene glycol (CCEG) were suitable for the extraction. The optimum extraction process was as follows: water content, 27%; extraction temperature, 62 °C; and extraction time, 48 min. With the abovementioned parameters, the predicted extraction yield of LRCP was 14.1%. It was found that with these optimal extraction conditions, a 52.9% higher extraction yield could be achieved compared with hot water extraction. Therefore, a type of DES was found to be an excellent extraction solvent alternative for the extraction of polysaccharides and has a practical value.

“…Specifically, when the water content in the DES system was increased from 10% to 20%, the polysaccharide yield increased significantly. However, further increasing the water content (20-50%) led to a decrease in the extraction efficiency, which may be attributable to the high concentration of water limiting the reaction between the polysaccharides and the DES [10]. Therefore, a water content of 20% was considered optimal and used in subsequent experiments.…”

“…Owing to their biocompatibility, low toxicity and various advantageous chemical properties, such as high thermal stability [9], high conductivity, low volatility, lack of flammability and non-reactivity with water, DESs are considered a sustainable option for extracting natural products from plants in various contexts. Moreover, they hold the potential to replace volatile organic solvents and ionic liquids [10]. Several reviews have highlighted the intriguing physicochemical properties of DESs and their applications in the fields of extraction [11], organic synthesis [12], nanomaterials [13] and sustainable pulping technology [14].…”

In this study, an ultrasound-assisted green extraction method was applied for the extraction of polysaccharides from Radix Peucedani based on deep eutectic solvents (DESs), and the result showed that a DES system composed of betaine and 1,2-propylene glycol with a molar ratio of 1:2 possessed the optimal extraction efficiency for polysaccharides. Single-factor and Box–Behnken designs were used to determine the optimum extraction conditions for the maximum yields of polysaccharides from Radix Peucedani by using DESs. The maximum yields of polysaccharides attained 11.372% within a DES water content of 19%, an extraction time of 36 min, an extraction temperature of 54 °C, a solid–liquid ratio of 1:30 and an ultrasonic irradiation power of 420 W. The physicochemical properties of polysaccharides were analyzed using ICS and FT-IR, and the structure morphology was observed by SEM. The polysaccharides extracted from Radix Peucedani exhibited general antioxidant activities in vitro including DPPH, Hydroxyl and ABTS+ radical-scavenging activity. The antioxidant mechanism of Radix Peucedani polysaccharides was investigated using network pharmacology and molecular docking methods. The result showed that the high binding activity of glucose and IL1B, galactose and CASP3 was recognized as a potential mechanism for the antioxidant effects of Radix Peucedani polysaccharides.

“…Plant polysaccharides, as highly polar macromolecules, possess the characteristic of being soluble in water but insoluble in ethanol. Therefore, they are generally extracted using the water extraction method [1] . This method is advantageous due to its simple principles and ease of operation.…”
