Fructooligosaccharides have been isolated from roots and leaves of Stevia rebaudiana, by hot aqueous extraction, followed precipitation with ethanol. Their structure has determined using methylation NMR analysis, MALDI-TOF, ESI-MS. contained almost exclusively (2→1)-linked β-fructofuranosyl, terminal α-glucopyranosyl β-fructofuranosyl units. MALDI-TOF ESI-MS analyses showed the wide range degree polymerisation (DP) present in various extracts. From leaves, three different fractions gave...
Abstract Background Mushroom polysaccharides have traditionally been used for the prevention and treatment of a multitude disorders like infectious illnesses, cancers various autoimmune diseases. Crude mushroom extracts tested without detailed chemical analyses its polysaccharide content. For present study we decided to chemically determine carbohydrate composition semi-purified from 2 closely related well known basidiomycete species, i.e. Agaricus bisporus A. brasiliensis their effects on...
Microwave-assisted extraction (MAE) and pressurized liquid (PLE) were compared as advanced technologies to obtain polysaccharides (particularly biologically active β-glucans) from Pleurotus ostreatus Ganoderma lucidum fruiting bodies. Extraction effectiveness was by a full-factorial experimental design (response surface methodology, RSM), using water solvent. Total carbohydrate content of the obtained extracts polysaccharide yields variable responses investigated, while temperature time...
A polysaccharide-enriched extract obtained from Lentinula edodes was submitted to several purification steps separate three different D-glucans with β-(1→6), β-(1→3),(1→6) and α-(1→3) linkages, being characterized through GC-MS, FT-IR, NMR, SEC colorimetric/fluorimetric determinations. Moreover, in vitro hypocholesterolemic, antitumoral, anti-inflammatory antioxidant activities were also tested. Isolated glucans exerted HMGCR inhibitory activity, but only β-(1→6) fractions showed DPPH...
In this study, the production of exopolysaccharides (EPS) by three strains Lactobacillus was investigated, and plantarum CNPC003 identified as largest producer. EPS higher (568.4 mg/L) in MRS medium added with fructooligosaccharide (FOS) than control containing glucose (378 mg/L). Carbohydrate protein content FOS were 36.95 ± 0.24 g/100g 0.68 0.08 g/100g, respectively, while GLU showed 42.48 0.04 carbohydrate 0.87 0.05 protein. Infrared spectroscopy analysis confirmed polysaccharide...
In the face of interindividual variability and complexity gut microbial communities, prediction outcomes from a given fiber utilized by many microbes would require sophisticated comprehension all competitive interactions that occur in gut. Results presented here suggest high-specificity fibers potentially circumvent scope for utilization, providing promising path to targeted predictable shifts different individuals.
Teas from Maté have been widely consumed for centuries in Brazil, Argentina, Paraguay, and Uruguay. We now determine how age, growth conditions post-harvesting processes of leaves Ilex paraguariensis affect the concentration bioactive compounds their antioxidant capacity. Phenolics, xanthines, carbohydrates were identified quantified by electrospray ionisation mass spectrometry (ESI-MS) ultra performance liquid chromatography (UPLC), which dramatically reduces time each analysis (<3 min). On...
The Ascomycete Cordyceps militaris, an entomopathogenic fungus, is one of the most important traditional Chinese medicines. Studies related to its pharmacological properties suggest that this mushroom can exert interesting biological activities. Aqueous (CW and HW) alkaline (K5) extracts containing polysaccharides were prepared from mushroom, a β-D-glucan was purified. This polymer analysed by GC-MS NMR spectrometry, showing linear chain composed β-D-Glcp (1→3)-linked. six main signals in...
Medicinal health benefits uses of edible as well non-edible mushrooms have been long recognized. The pharmacological potential mushrooms, especially antitumor, immunostimulatory and anti-inflammatory activities has documented. Wild ectomycorrhizal mushroom, Lactarius rufus had the antinociceptive their polysaccharides evaluated using formalin model. Two structurally different (1→3),(1→6)-linked β-d-glucans were isolated from fruiting bodies. Soluble (FSHW) β-d-glucan 1–30 mg kg−1 produced...
For many years mushrooms have been consumed and appreciated by their nutritional value, medicinal properties. The traditional mushroom cultivation takes too long the macrofungi biotechnology has not explored in its full potential yet. goal of this work was to observe if different carbon sources could improve yield diversify fungi nutrient composition submerged culture. Pleurotus pulmonarius mycelia exopolysacharide productions were evaluated using glucose, galactose, xylose arabinose. varied...
