The ultrasonic-assisted enzymatic extraction, characteristics and antioxidant activities of lychee nuclear polysaccharide

Ultrasonics Sonochemistry, Journal Year: 2024, Volume and Issue: 110, P. 107038 - 107038

Published: Aug. 23, 2024

A response surface methodology (RSM) and one-factor method were established to investigate the optimum conditions for extraction of lychee nuclear polysaccharides (LSP) by ultrasonic-assisted pectinase. The content basic components in was determined. antioxidant activity well determined compared differences activities extracted water (LSP-HW) those at ultrasound-assisted enzyme (LSP-UAE). polysaccharide increased with increase concentration. anti-hydroxyl radical anti-lipid peroxidation abilities more excellent, LSP-HW slightly better than LSP-UAE terms activity, but difference not significant. In solubility; without deproteinization best, followed LSP-UAE, worst after deproteinization. higher glycoprotein content, solubility its polysaccharide. Compared existing methods, this experiment greatly improved rate further enriched polysaccharides.

Ultrasound-assisted enzyme extraction of Dendrobium Officinale polysaccharides: Extraction process, characterization, immunomodulatory effects

Ultrasonics Sonochemistry, Journal Year: 2025, Volume and Issue: 114, P. 107248 - 107248

Published: Feb. 1, 2025

Dendrobium Officinale is a traditional Chinese medicinal and edible herb, polysaccharides being its principal active components. We employed ultrasonic-assisted enzymatic extraction to obtain from (DOP) optimized the process using GA-BP method. Subsequently, DOP was characterized HPLC, SEM, HPGPC. Finally, an immunocompromised mouse model induced by cyclophosphamide adopted evaluate immunomodulatory effects. The results showed that optimal of ultrasound-assisted enzyme method 102 min ultrasonic time, 48 °C temperature, 1:80 material-liquid ratio, 1600 U/g additions. predicted polysaccharide yield 29.64 %, actual 29.71 ± 0.31 %. white powder with pore-like structure, whose content 90.66 2.47 composition D-mannose, glucose, galactose, arabinose in molar ratio 74.17: 47.80: 9.03: 1. has demonstrated ability improve general condition mice cyclophosphamide-induced immunosuppression. It mitigates damage thymus spleen tissues, increases blood cell counts, regulates T lymphocytes levels related factors, enhances macrophage phagocytic function nonspecific immune responses, boosts immunoglobulins IgA IgG enhance specific function. Therefore, can alleviate immunosuppression cyclophosphamide.

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.
