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

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Фев. 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.

The antioxidant activity of shaddock peel polysaccharides

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Март 21, 2025

The shaddock peel polysaccharide (SPP) has various biological activities. This explored its antioxidant activity. In vitro tests, the two SPP components showed good DPPH, hydroxyl radical scavenging ability and anti-lipid peroxidation ability. At a concentration of 3.2 mg/mL, abilities polysaccharides were 21.65% 18.96%, respectively. SPP-3 had slightly stronger to scavenge radicals than SPP-2. When reached order polysaccharides' DPPH rates was SPP-2 > SPP-3. Therefore, strong activity could be used in antioxidant-related applications future.
