Yang, Bing published the artcileHigh-pressure ultrasonic-assisted extraction of polysaccharides from Hovenia dulcis: Extraction, structure, antioxidant activity and hypoglycemic, SDS of cas: 59-23-4, the main research area is Hovenia polysaccharide antioxidant hypoglycemic HUE; Antioxidant activity; Carbohydrate chemistry; Diabetes; High-pressure ultrasonic-assisted extraction; Hovenia dulcis; Rheological properties.

In this study, high-pressure ultrasonic-assisted extraction (HUE) technol. was used for polysaccharide extraction from Hovenia dulcis (HDPS). A maximal extraction yield (11.81 ± 0.26%) was obtained using the response surface method (RSM) with optimized HUE conditions (Ultrasound power 330 W, 68 °C, and 22 min). Results showed that HDPS mainly contained neutral sugar (47.81 ± 1.56%), uronic acid (12.52 ± 0.15%), and protein (3.64 ± 0.24%), specifically. HDPS was comprised of mannose, rhamnose, galacturonic acid, glucose, galactose and arabinose in a molar ratio of 3.20%, 20.40%, 4.81%, 11.14%, 27.37% and 33.08%, resp. And with an average mol. weight of 185.22 kDa for its major component (accounting for 90.13% for HDPS). The result obtained from the X-ray diffraction pattern confirmed a semi-crystalline nature of the sample. HUE-HDPS suggested typical shear thinning behavior and non-Newtonian properties. Addnl., HUE-HDPS exhibited better chem. antioxidant activities in DPPH, ABTS, hydroxyl radical scavenging and Fe2+ chelation activity. The in-vitro and in-vivo experiments indicated that HUE-HDPS had obviously hypoglycemic effects. Accordingly, the polysaccharides from Hovenia dulcis might serve as a natural antioxidant and hypoglycemic agent.

Zhang, Wenyi published the artcileUltrasonic-assisted enzymatic extraction of Sparassis crispa polysaccharides possessing protective ability against H2O2-induced oxidative damage in mouse hippocampal HT22 cells, Recommanded Product: (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, the main research area is Sparassis hippocampal cell ultrasonic assisted enzymic extraction polysaccharide.

Sparassis crispa polysaccharides have recently attracted considerable attention due to their excellent bioactivities. However, their extraction procedure is often tedious, time-consuming, and environmentally unfriendly; it even causes damage to their structures and reduces their bioactivities, all of which hinder their further development to some extent. Therefore, the ultrasonic-assisted enzymic extraction (UAEE) technol. was optimized to extract polysaccharides from Sparassis crispa (SCP) by the response surface methodol. The yields, physicochem. properties, and antioxidant activities of SCPs obtained from UAEE and conventional hot water extraction (HWE) were evaluated. According to the optimal parameters, the yield of SCPs extracted by UAEE reached up to 14.63%, which increased by 68.54% compared with that obtained from the conventional hot water extraction (HWE) method. Addnl., the UAEE methods affected the contents of the polysaccharides, mol. weights, and the molar percentage of the constituent monosaccharides of SCPs. SEM anal. indicated that the microstructures of the two SCPs were notably different. Antioxidant assays showed that both SCPs possessed good antioxidant activities against DPPH, ABTS +, and hydroxyl radicals in vitro. Addnl., the SCPs extracted by UAEE attenuated the HT22 cell neurotoxicity induced by H2O2 by the means of ameliorating cell viability, reducing extracellular LDH release, and decreasing the levels of intracellular ROS.

In this study, different extraction methods of polysaccharides from Crataegus pinnatifida Bunge (CPP) were compared by studying the extraction yield, structural characteristics and antioxidant activities. Firstly, polysaccharides were obtained using hot water extraction (CPPh), ultrasound assisted extraction (CPPu), enzyme assisted extraction (CPPe) and enzyme-ultrasound assisted extraction (CPPc), resp. Meanwhile, the optimum extraction conditions of enzyme-ultrasonic assisted extraction were determined by response surface method (RSM). The extraction yields, structural characteristics and antioxidant activities were investigated and compared by visual photos, gas chromatog., UV-visible and Fourier-transform IR spectroscopy. The results clearly showed that enzyme-ultrasonic assisted extraction possessed the highest extraction yield (10.39 ± 0.04%). The mol. weight of CPPh was the highest while the other polysaccharides had no significant difference. Besides, the monosaccharide composition of CPPc, CPPh, CPPu and CPPe were similar but the molar percentages of monosaccharide were different. Finally, the results of antioxidant activities showed that CPPc exhibited the highest scavenging effect of superoxide radical and lipids inhibiting ability. In summary, enzyme-ultrasonic assisted extraction was a high-efficient and low-energy consumption method for CPP extraction

Wu, Hongyan published the artcileComparison of different extraction methods of polysaccharides from cup plant (Silphium perfoliatum L.), Related Products of alcohols-buliding-blocks, the main research area is Silphium polysaccharide enzyme assisted hot water extraction method.

The purpose of the present research was to compare the effects of four extraction methods on the extraction yields, physicochem. characteristics, and antioxidant activities of polysaccharides from the cup plant (Silphium perfoliatum L.) (CPPs). The extraction methods included the hot water extraction method (HEM), ultrasonic-assisted extraction method (UEM), enzyme-assisted extraction method (EEM), and the ultrasonic-enzyme-assisted extraction method (UEEM). Four corresponding CPP extracts, HEM-CPPs, UEM-CPPs, EEM-CPPs, and UEEM-CPPs, were obtained. The results indicated that there were notable differences between the extraction methods regarding the yield, average mol. weight, uronic acid content, monosaccharide proportions, and the antioxidant activities of the CPPs. HEM-CPPs were extracted with the lowest yield (6.44%). EEM-CPPs had the largest extraction yield (9.87%) and the most notable antioxidant abilities of ferric reducing power and free radical scavenging activity. According to correlation anal., the higher antioxidant abilities of EEM-CPPs might be due to their smaller average mol. weight and a higher content of uronic acid than those of the other extracted CPPs. Therefore, EEM could serve as a promising technique for extracting CPPs.

Fahmi, Abdelgawad published the artcilePhytochemicals, antioxidant activity and hepatoprotective effect of ginger (Zingiber officinale) on diethylnitrosamine toxicity in rats, Synthetic Route of 124-76-5, the main research area is ginger diethylnitrosamine toxicity phytochem antioxidant activity hepatoprotective effect; Diethylnitrosamine toxicity; essential oil; ginger; hepatoprotective effect.

Chronic liver damage has serious medical consequences. To investigate the hepatoprotective effect of dry Zingiber officinale (ginger) and its essential (volatile) oil against diethylnitrosamine (DEN) toxicity in rats. Phenols and flavonoids components were characterized in dry ginger using HPLC-UV instrument while ginger essential oil (E.O.) was investigated via GC-MS technique. Antioxidant activity was determined in-vitro. In rat model, ginger was administrated for 2 mo. Lipid profile, antioxidant biomarkers, liver functions and histopathol. were assessed. Chlorogenic acid (63.85ppm) and hesperidin (156.91ppm) are among the major phenolic and flavonoid constituents in dry ginger. Curcumene (15.21%) and linalool (13.47%) represent the main E.O. constituents. In rats treated with ginger E.O., a significant elevation in serum HDL (31.14%) was accompanied by a decrease in LDL (55.14%). A significant decrease in serum ALT and ALP was reported (56.85% and 53.84%, resp.). Serum GSH-Px activity has significantly increased 75.06%. Meanwhile, E.O. showed anticancer potential against HepG2 cell line (IC50 = 40μg/mL). Liver histopathol. examinations confirmed the protective effect against abnormalities. Ginger was able to reduce the severity of DEN-cytotoxicity in rats, which suggests a novel antioxidant role originating from this medicinal plant.
