Polysaccharides from Bergenia emeiensis (PBE) showed a robust antioxidant ability on scavenging free radicals in vitro. However, the further antioxidant potential in cell level and in vivo was still unknown. Therefore, in this present study, the protective effect of PBE on human cervical carcinoma cell (Hela) cells and Caenorhabditis elegans against oxidative stress was evaluated. The results showed PBE could reduce the reactive oxygen species (ROS) level in Hela cells and promote the mitochondrial membrane potential. Then, the cell apoptosis was reduced. Moreover, PBE could enhance the survival of C. elegans under thermal stress to 13.44%, and significantly reduce the ROS level, which was connected with the overexpression of sod-3 and the increased nuclear localization of daf-16 transcription factor. Therefore, PBE exhibited a strong antioxidant capacity in the cellular level and for a whole organism. Thus, polysaccharides from B. emeiensis have natural potential to be a safe antioxidant.

“…In particular, polysaccharides isolated from functional and medicinal foods as well as from common foods have drawn great attention in antioxidant studies. Here, we attempt to summarize recent studies of antioxidant polysaccharides from food resources, including vegetables, fruits, cereals, beans, mushrooms, tea, milk products and meat ( Table 1 ) [ 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 ].…”

Oxidative stress is known to impair architecture and function of cells, which may lead to various chronic diseases, and therefore therapeutic and nutritional interventions to reduce oxidative damages represent a viable strategy in the amelioration of oxidative stress-related disorders, including neurodegenerative diseases. Over the past decade, a variety of natural polysaccharides from functional and medicinal foods have attracted great interest due to their antioxidant functions such as scavenging free radicals and reducing oxidative damages. Interestingly, these antioxidant polysaccharides are also found to attenuate neuronal damages and alleviate cognitive and motor decline in a range of neurodegenerative models. It has recently been established that the neuroprotective mechanisms of polysaccharides are related to oxidative stress-related pathways, including mitochondrial function, antioxidant defense system and pathogenic protein aggregation. Here, we first summarize the current status of antioxidant function of food-derived polysaccharides and then attempt to appraise their anti-neurodegeneration activities.

“…We observed that the inhibition activities of Camellia oleifera Abel water extract against barnyardgrass were significantly higher than that of the other 20 species of plants belonging to the 12 families tested (Zhong et al, 2008), while screening natural products high herbicidal activity. This species has been demonstrated to have potential as a natural fungicide (Lee and Yen, 2006;Hu et al, 2012;Jin and Ning, 2012), antioxidant (Chang and Shyu, 2007;Chen et al, 2010;Zhang et al, 2010;Ye et al, 2013;Feng et al, 2014) or insecticide (Wei et al, 2005;Potter et al, 2010). However, little is known about the phytotoxicity of C. oleifera extracts for the sustainable management of weeds.…”

Five fractions (named A1, A2, A3, A4 and A5, which obtained by the sequential solvent extraction and purification, see Fig. 1) were isolated from the methanol extracts of the stems and leaves of Camellia oleifera Abel. The inhibitory activities of these fractions against Echinochloa crusgalli L. were determined, and the biochemistry and physiology of A1 against barnyardgrass was investigated. The results indicated that the inhibition activity of A1 was significantly higher than that of the other four tested fractions. When treated prior to seed germination using the cup culture method, the concentration for 50% reduced activity (IC50) of seed germination, shoot length, radical growth and fresh weight were 0.0034, 0.0011, 0.0005 and 0.0021 g/mL, respectively, against barnyardgrass, while treatment after seed germination resulted in IC50 values of 0.0017, 0.005 and 0.0017 g/mL, respectively. In addition, the results indicated that the root activity, total amino acid contents and α-amylase and total amylase activities in barnyardgrass decreased with increasing A1 concentrations. The purified B21 fraction was identified as gallic acid using 1 H NMR and MS analyses. These results suggest that the fractions and active compounds isolated from the methanolic extract of the stems and leaves of C. oleifera showed potent weed control activity and might have potential as a botanical pesticide for the regulation of plant growth.
