Antioxidant and anti-ageing effects of enzymatic polysaccharide from Pleurotus eryngii residue

Physicochemical property and antioxidant activity of polysaccharide from the seed cakes of Camellia oleifera Abel

“…In the Morris water maze analysis, escape latency, number of target platform crossings, and percentage of time in target quadrant are frequently applied to evaluate the effects of natural products on rodents' spatial learning and memory ability (Tao et al., 2018 ; Wang, Zhang, et al., 2020 ; Wang, Huo, et al., 2020 ; Zhang et al., 2021 ). As indicated from Figure 4a , the escape latency reduced gradually from day 1 to day 5, suggesting the learning capacities of mice were effectively improved under the training.…”

“…Malondialdehyde, the end‐product of lipid peroxidation, is capable of interfering with lipid metabolism and accelerating lipid peroxidation, thereby probably creating cellular oxidative stress (Zhang et al., 2021 ). As displayed in Figure 7 , MDA contents in serum, brain, liver, kidney, and heart of mice in the MC group were significantly higher than those in the NC group.…”

“…D‐gal can not only lead to memory and cognitive impairment but also change the similar significant aging characteristics, such as MDA content and the activities of SOD and GSH‐Px (Zheng, 2020 ). Accordingly, D‐gal‐induced aging animal model had been extensively adopted to investigate the in vivo antiaging and antioxidant effects of polysaccharides (Li et al., 2018 ; Yang et al., 2019 ; Zhang et al., 2021 ). Thus, a D‐gal‐induced aging mice model was used to evaluate the in vivo antioxidant activity of the obtained polysaccharide from seed cakes of Camellia oleifera Abel.…”

β-1,6-Glucan From Pleurotus eryngii Modulates the Immunity and Gut Microbiota

“…Polysaccharides isolated from P. eryngii have attracted considerable attention in recent years due to their low toxicity and broad-based biological activities ( 8 , 41 ). Previous reports showed that linear (1→6)-β-glucan ( 8 ), branched (1→3)-β-glucan ( 9 ), 3-O-methylated heterogalactan ( 6 ) and heteropolysaccharides ( 10 ) have been found in P. eryngii .…”

Transcriptome analysis reveals the potential mechanism of polyethylene packing delaying lignification of Pleurotus eryngii

“…Pleurotus eryngii belongs to Pleurotaceae, Agaricomycotina, Basidiomycota, Fungi. P. eryngii contains various bioactive substances such as terpenoids, sterols, polysaccharides and polyphenols, which can be developed into natural and functional foods and drugs to resist reactive free oxygen species, delay the aging process, and improve postprandial blood glucose ( Kleftaki et al, 2022 , Zhang et al, 2021 ). The post-harvest physiological state of P. eryngii is susceptible to various environmental factors, including temperature, humidity, gas environment and other microbial community infections.…”
