Isolation, In Vitro Antioxidant Capacity, Hypoglycemic Activity and Immunoactivity Evaluation of Polysaccharides from Coriandrum sativum L.

Antioxidants, Journal Year: 2025, Volume and Issue: 14(2), P. 149 - 149

Published: Jan. 27, 2025

Coriander (Coriandrum sativum) is a classical medicinal and edible herb as well spice, but the physicochemical biological properties of its polysaccharides have not been fully studied. In this study, were extracted using an ultrasonic-assisted method purified from fresh coriander, then coriander polysaccharide (CSP) fraction was separated agarose gel Q-Sepharose Fast Flow column. The total sugar content, protein content monosaccharides composition CSPs determined phenol–sulfuric acid method, Coomassie Brilliant Blue HPLC. structural characterization detected ultraviolet spectrophotometry FT-IR spectroscopy. DPPH ABTS free radicals used to explore their antioxidant activities, while inhibitory abilities α-amylase α-glucosidase evaluate hypoglycemic activity. After that, immunomodulatory antitumor activities investigated macrophage RAW264.7 HepG2 cells targets. results showed that contents 66.90 ± 1.44% 1.06 0.32%, respectively. mainly composed fucose, rhamnose, arabinose, galactose, glucose, galacturonic glucuronic acid, with molar ratio 1.13:15.11:9.60:25.98:1.55:44.33:2.29, may be acidic heteropolysaccharide containing pyran rings, α- β-glycosidic bonds acid. Results in vitro experiments IC50 for scavenging 0.759 mg/mL 1.758 mg/mL, respectively; values inhibiting 0.634 2.178 concentration 25~200 μg/mL no obvious toxicity RAW264.7, when treated 100 CSPs, relative cell phagocytosis capacity secreted nitric oxide amount 153.75 12.01% 133.56 5.37%, concentration-dependent ability inhibit growth within test 0.25–2.0 mg/mL. Summarizing results, due excellent antioxidant, anti-tumor expected show good potential comprehensive development food medicine.

Ultrasound‐enzyme‐assisted extraction of flavonoids, polysaccharides, and triterpenes from Gualou and Xiebai: optimization, bioactivity, in vitro digestive stability, and impact on lipid digestion

Journal of Food Science, Journal Year: 2025, Volume and Issue: 90(2)

Published: Feb. 1, 2025

Gualou (Trichosanthes kirilowii Maxim) and Xiebai (Allium macrostemon Bunge) have been extensively studied for their diverse active ingredients, which include flavonoids, polysaccharides, triterpenoids. This study employed a single-factor experiment alongside the Plackett-Burman design utilized response surface methodology to optimize ultrasonic-enzyme-assisted extraction (U-EAT) method functional components in (GLXB). The optimal conditions were identified as solid-to-liquid ratio of 1:11 g/mL, an alcohol concentration 55%, enzyme 1.2%, temperature 40°C. yields triterpenoids obtained 0.94 ± 0.05, 260.46 1.78, 118.69 0.71 mg/g, respectively, demonstrating increases 59.19%, 29.03%, 46.10% compared HL (HL, traditional reflux method). Furthermore, vitro digestion GLXB extract demonstrated significant lipid-lowering hypoglycemic effects. facilitated flocculation lipid droplets during exhibited capacity reduce rate fat digestion. These findings indicate that U-EAT significantly enhanced content ingredients improved activities extract, highlighting its potential further development application foods.

Ultrasound-assisted enzymatic extraction, process optimization, and antioxidant activity of polysaccharides from sugarcane peel

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Feb. 11, 2025

In this research, ultrasound-assisted enzymatic extraction of sugarcane peel polysaccharides and optimization process conditions were used to investigate their properties antioxidant activities. The effects liquid-material ratio, ultrasonic temperature, time, cellulase dosage on the rate SPP investigated by one-way experiments response surface analysis determine optimal conditions. Meanwhile, structural characterization (FT-IR NMR analyses) activity studies (DPPH hydroxyl radical scavenging rates) carried out total sugar content SPP. results showed that for method 40 mL/g 50 °C ultrasound min 5% enzyme dosage, yield was 5.38% 75.52% under these extracted some ability both DPPH radicals, 54.63% 33.91%, respectively, when mass concentration solution 4 mg/mL. present study demonstrated enzymes can effectively extract with activity, which provides a theoretical basis developing utilizing has potential application value.
