Optimization of cellulase‐assisted extraction process and antioxidant activities of polysaccharides from Tricholoma mongolicum Imai

Abstract

TMIPs show moderate antioxidant activities in vitro. Therefore it is suggested that TMIPs are potential natural antioxidants for use in functional foods. © 2016 Society of Chemical Industry.

Enzyme Assisted Extraction, Purification and Structure Analysis of the Polysaccharides from Naked Pumpkin Seeds

“…In addition, Chen, Zhou, & Zhang proved that the polysaccharides from Astragalus membranaceus extracted by enzyme assisted extraction had better antioxidant activity (about 2 times higher) than none enzyme treated ones [2]. Moreover, EAE has been used to separate the polysaccharides from Malva sylvestris [9], Lentinus edodes [10], Panax ginseng [11], and Polygonatum odoratum [12], all these results further confirmed that EAE could be widely applied to the polysaccharide field.…”

Microencapsulation of Bifidobacterium bifidum BB01 by xanthan–chitosan: preparation and its stability in pure milk

“…For 2D contour plot, the shape can explain the significance of mutual interactions between independent variables. 3D response surface plot can exhibit the mutual effects of independent variables on the response variable [23]. For chitosan Figure 2.…”

“…where Y is the predicted response, b 0 , b i , b ii and b ij represent the constant coefficient, linear, quadratic and cross product effects of the X 1 , X 2 and X 3 factor responses, respectively [23]. SAS version 9.1 (Statistical Analysis System, Cary, NC) was used to analyse the experimental data and calculate the predicted responses.…”

In vitro Antioxidant Activities of Natural Polysaccharides: An overview

“…In addition, a polysaccharide from Hericium erinaceus mushrooms exhibits a strong in vitro antioxidant activity in addition to neuroprotective effects on β-induced neurotoxicity in neurons (Cheng, Tsai, Lien, Lee, & Sheu, 2016). Furthermore, polysaccharides extracted from the edible mushroom Tricholoma mongolicum exhibited in vitro antioxidant activities in a dose-dependent manner (Zhao et al,2016) while fucogalactomannan obtained from the Tylopilus ballouii mushroom inhibited superoxide and hydroxyl radicals with IC 50 values of 1.25 and 1.6 mg/mL, respectively (Lima et al, 2016). Moreover, a water-soluble β-glucan isolated from the hot water extract of the edible mushroom Entoloma lividoalbum (Kühner & Romagn) Kubička stimulated the production of macrophages, splenocytes, and thymocytes, in addition to exhibiting hydroxyl and superoxide radical scavenging activities and reducing properties (Maity, et al, 2015).…”
