Characterization of antioxidant polysaccharides from Auricularia auricular using microwave-assisted extraction

Structural Characterization and Biological Activities of Polysaccharides from Olive Mill Wastewater

“…It was observed that WSF also had strong scavenging activity, with an IC 50 value of 89.43±2.65 μg/ mL. Previous studies had showed that structures of polysaccharides and proteins linked to polysaccharides had closely relationships with their antioxidant activity [44,[50][51][52]. So, the remarkable antioxidant activity of WSF may be attributed not only to its polysaccharides but also to its polyphenols and protein content.…”

Microwave-Assisted Extraction of Polysaccharides

“….) have been attributed to polysaccharides (Simões et al 2009;Zeng et al 2012;Holck et al 2014), as mentioned in previous chapters. Extraction of these compounds from plant and food sources has attracted a great deal of interest with a view to provide natural extracts rich in bioactive ingredients of potential application, among others, in the food industry.…”

Characterization and antioxidant properties of crude water soluble polysaccharides from three edible mushrooms

“…Furthermore, it is also reported that the band between 1627 and 1651 cm -1 was due to the bound water (Park, 1971). The characteristic band near to the 1,038.39 and 1,037.13 cm -1 area showed a pyranose form of sugar (Zeng et al, 2012). The selected polysaccharide had a particular band in the 1,200 to 1000 cm -1 area, between the stretching vibration of (C-OH) side groups and the (C-O-C) glycosidic band vibration (Zhao et al, 2007).…”

“…The selected polysaccharide had a particular band in the 1,200 to 1000 cm -1 area, between the stretching vibration of (C-OH) side groups and the (C-O-C) glycosidic band vibration (Zhao et al, 2007). The absorptions between (707.87 to 536.08 cm -1 ) of the spectrum were characteristic of mannose (Chen, 2012) (Figure 1). …”
