Extraction and antioxidant activities of intracellular polysaccharide from Pleurotus sp. mycelium

Influence of fermentation concentrate of Hericium caput-medusae (Bull.:Fr.) Pers. on performance, antioxidant status, and meat quality in broilers

“…Mushroom polysaccharides primarily exist as linear and branched glucans with different types of glycosidic linkages, such as ␤-(1 − 3), (1 − 6)-glucans and ␣-(1 − 3)-glucans; however, some are true heteroglycans containing glucuronic acid, xylose, galactose, mannose, arabinose, or ribose (Lee et al, 2012). In addition to providing the requirements for biological metabolism and energy, these polysaccharides also exhibit antiviral, antibacterial, and antiparasitic functions (Wasser and Weis, 1999;Liu et al, 2010). ␤-1-3-d-Glucan and its derivatives possess immune-stimulating activity and various levels of free-radical-scavenging activity (Tsiapali et al, 2001).…”

“…Phenolic compounds are widely found as secondary metabolites in plants and mushrooms, and the contents can be used as a critical index for determining the antioxidant capacity (Wu and Hansen, 2008;Liu et al, 2010). Some mushrooms have been found to possess significant in vitro antioxidant activity, which was well correlated with their total phenolic content Yang et al, 2002;Cheung et al, 2003;Lo and Cheung, 2005;Ferreira et al, 2007;Reis et al, 2012).…”

Antioxidant and Anti-Tyrosinase Activity from Olea Leaf Extract Depended on Seasonal Variations and Chromagraphy Treatment

“…Superoxide radicals were generated by pyrogallic acid method with some modification [12][13][14]. The reaction mixture contained 2 mL sample (0.0 -1 mg/mL) dis-solved in 2.25 mL Tris-HCl buffer (0.05 M, pH 8.0).…”

Physicochemical characteristics of ultrasonic extracted polysaccharides from cordyceps cephalosporium mycelia

“…However, HWE requires high extraction temperature and is quite timeconsuming. In recent years, ultrasonic extraction (USE) has been widely used in natural products extraction process and it has been developed as an efficient alternative to conventional extraction techniques [11,12]. However, rather limited research has investigated ultrasonic extraction of intracellular polysaccharides from CCM.…”
