Physicochemical properties and in vitro bioactivities of polysaccharides from lotus leaves extracted by different techniques and solvents

Exploring carbohydrate extraction from biomass using deep eutectic solvents: Factors and mechanisms

“…For example, treating Panax quinquefolius with DES (20% water) yielded 87.02% sugar. 131 However, the carbohydrates from lotus leaves treated with 30% moisture was 83.20%, 133 while the sugar yield of lotus leaves treated with 61.0% moisture content was only 5.38%. 134 The xylose yield from herbal residues of Heteropogon contortus was only 6.17% treated with ChCl- p -coumaric acid without water, while the yield increased to 82.50% when DES: water = 2: 1.…”

“…For instance, when extracting OPEFB using DES (ChCl-U), the glucose production rate increased from 59.12 mg/mL to 61.96 mg/mL with an increase in extraction time from 1 h to 4 h. 107 On the other hand, when treating lotus leaves with DES (ChCl: Ethylene chloride), the yield of carbohydrates obtained after 6.5 min (83.20%) was higher than that obtained after 3 h (77.89%). 133 The liquid-solid (L/S) ratio is another parameter affecting carbohydrates extraction using DESs. While Table 2 lists the L/S ratio parameters as L/S = 10:1 mL/g, L/S = 20:1 mL/g, and L/S = 30:1 mL/g, the optimal ratio for extracting various biomass polysaccharides using DES must be determined through experimentation.…”

The Most Potent Natural Pharmaceuticals, Cosmetics, and Food Ingredients Isolated from Plants with Deep Eutectic Solvents

“…Polysaccharides extracted from lotus leaves were examined in terms of their antioxidant capacities. Through extraction with DESs, the antioxidant properties of compounds were more intense compared to the extracts isolated with water . Other interesting natural chemicals are alkaloids with potential anti-inflammatory bioactivities.…”

“…Through extraction with DESs, the antioxidant properties of compounds were more intense compared to the extracts isolated with water. 236 Other interesting natural chemicals are alkaloids with potential anti-inflammatory bioactivities. This group of compounds has many possible applications, such as the improvement of immunological defense and the treatment of cardiovascular and liver diseases.…”

“…This group of compounds has many possible applications, such as the improvement of immunological defense and the treatment of cardiovascular and liver diseases. − Carotenoids are chemicals that are commonly present in edible plants, but due to their hydrophobic nature, the recent literature focuses on applying hydrophobic DESs in their extraction Table presents a brief review on other chemicals extracted using DESs. ,,− …”
