In this study, Shatian pomelo peel was used as the raw material for extracting polysaccharides using hot water extraction (HW) and ultrasonic-assisted enzyme (UVE) methods, respectively. The optimal parameters extractingShatian (StPP) ultrasound-assisted enzymatic method were determined response surface methodology (RSM). conditions of StPP follows: ultrasound power 350 W, time 50 min, digestion compound addition 1.5%, temperature 55 °C. yield found to be 30.1310% under these conditions. Comparing physicochemical properties antioxidant activity extracted different it observed that resulted in higher yield, sugar content glucuronic acid compared traditional extraction. Additionally, by showed better activity. These results suggest is an effective enhance natural polysaccharides.

Ultrasonics Sonochemistry, Год журнала: 2024, Номер 108, С. 106948 - 106948

Опубликована: Июнь 12, 2024

In this study, the process conditions, physicochemical properties, structural composition and activity of polysaccharides isolated from leechee peel (LPP) by ultrasound-assisted extraction (UAE) with enzyme alkali solution (ASE) were compared. The results showed that total sugar content LPP extracted UAE accounted for 75.65 %, which was significantly higher than solution. optimum conditions as follows: temperature 68.78 ℃, ultrasonic enzymolysis time 39.68 min, pectinase dosage 4.03 solid–liquid ratio 1:30 g/mL, power 360 W. antioxidant activities structure polysaccharide prepared under different It found UAE-LPP an α-type containing 15.83 % uronic acid. Moreover, strong in anti-lipid peroxidation reducing ability. Ultrasound-assisted enzymatic method is effective means to improve natural plant polysaccharides, has advantages short time-consuming, simple easy operation, can greatly utilization rate lay a theoretical scientific basis development LPP.

Ultrasonic-assisted extraction, analysis and properties of purple mangosteen scarfskin polysaccharide and its acetylated derivative

Ultrasonics Sonochemistry, Год журнала: 2024, Номер 109, С. 107010 - 107010

Опубликована: Июль 31, 2024

Purple mangosteen scarfskin polysaccharide has many important physiological functions, but its preparation method, structure, and function need further exploration. A was obtained from by ultrasonic-assisted extraction purified. On this basis, structure physicochemical properties were investigated. The Congo red experiment used to determine whether it a triple helix conformation. of purple analyzed infrared spectroscopy nuclear magnetic analysis. antioxidant activities the above three polysaccharides studied related experiments. It found that monosaccharide composition mainly contained large amount arabinose, small rhamnoose very galacturonic acid, core main chain composed 1,4-α-arabinose. did not have spatial configuration. After acetylation polysaccharide, acetylated derivative with degree substitution 0.33 obtained. they had certain scavenging inhibiting effects on hydroxyl radicals lipid peroxidation, their concentration polysaccharides. Meanwhile, activity significantly enhanced after modified treatment acetylation, which indicated chemical modification could effectively improve some polysaccharide. studies provided reference value for research development
