In this study, Chinese yam polysaccharide (CYP) was fermented by Saccharomyces cerevisiae CICC 32883, and its structural features antioxidant activities before after fermentation were analyzed. S. 32883-fermented CYP (CYP-SC) had higher carbohydrate content lower protein than the nonfermented (CYP-NF). The monosaccharide composition of CYP-SC unaffected, but proportion changed. Compared with CYP-NF's molecular weight polydispersity 124.774 kDa 6.58, respectively, those reduced to 20.384 3.379. Antioxidant results showed that better effects CYP-NF in scavenging DPPH, ABTS, hydroxyl, superoxide radicals. Moreover, enhancing oxidation capacity protecting HepG2 cells CYP-NF. Furthermore, on alleviating repairing H2O2-damaged are superior This work offers a green efficient method for activity dietary plant polysaccharides.

In the Azores Archipelago, Cryptomeria japonica is, currently, most cultivated forestry tree for timber production, landscaping, and gardening, generating large amounts of foliage waste that is used local essential oils (EOs) production. However, existing literature on biological potential EOs from different C. parts, such as female cones (FC), remains limited. Thus, in present study, extracted by hydrodistillation Azorean immature mature FC (IFC MFC), well some major EO components, were screened their: (i) antioxidant capacity, evaluated DPPH free-radical-scavenging activity (FRSA) β-carotene-linoleic acid bleaching (BCBA), (ii) antimicrobial activities, assessed disc diffusion method against eight bacteria one fungus, (iii) toxicity Artemia salina. Among both samples, IFC exhibited best DPPH–FRSA, BCBA, growth inhibitory Staphylococcus aureus, epidermidis, Bacillus subtilis, Penicillium italicum, a slightly increased toxic potential, due to their differential compositions, GC–MS analysis. FC’s maturation process decreased EOs’ bioactivities. conclusion, this finding could help determining optimal developmental stage enhancing compounds content EOs. turn, contributes increasing commercial japonica’s industry.
