Abstract: Using DMSO as solvent, ultrasonic-assisted extraction of polysaccharides from Grifola frondosa is studied. The effects of different extraction conditions on the yield of polysaccharides are investigated. The optimal extraction conditions are found by a Box-Behnken design. The results showed that the yield of Grifola frondosa polysaccharide can reach 6.94% under the following conditions: liquid-solid ratio of 33.8 mL g -1 , ultrasonic power of 104.6 W, extraction temperature of 35.6°C, and extraction time of 4.… Show more

In this study, the response surface method (RSM) was used to determine the optimal parameters of ultrasonic assisted extraction of Gymnocladus chinensis Baill. polysaccharides (GCBP). The optimal extraction conditions were as follows: a liquid‐solid ratio of 50.4 mL/g, an extraction temperature of 60 °C, an extraction time of 43 min, and an extraction power of 240 W. Under these conditions, the extraction rate of GCBP reached 50.1%. Three fractions of GCBP‐40, GCBP‐60 and GCBP‐80 with sugar contents of 64.33%, 59.16% and 59.46% were obtained by different concentrations of ethanol purification. All the three fractions were consisted of six monosaccharides with different ratio, namely Man, Rha, Gal, Glu, Ara and Xyl. From Congo red test, it is confirmed that all three fractions could have a triple helix structure. In addition, the antioxidant and hypoglycemic experiments showed that all three components had excellent antioxidant activity (DPPH free‐radical scavenging activity, ABTS free‐radical scavenging activity, and OH‐ free‐radical scavenging activity) and hypoglycemic activity (α‐glucosidase inhibitory activity).

Naematelia aurantialba (N. aurantialba) is a fungus rich in polysaccharides with medicinal and edible properties. Polysaccharides are the main active components of N. aurantialba; however, their biological activities and functional properties have not been widely explored. In this study, the ultrasonic extraction process for N. aurantialba polysaccharides (NAP) is optimized, and the physicochemical, functional, and antioxidant activities of the homogeneous fraction (NAP) are investigated. The optimal extraction conditions are a liquid–solid ratio of 50 mL g−1, ultrasonic power of 430 W, ultrasonic time of 32 min, resulting in an extraction rate of N. aurantialba polysaccharides of 48.68% ± 0.83%. NAP has a molecular weight of 915 kDa. The monosaccharide composition of NAP is as follows: mannose (59.04% ± 0.12%), xylose (23.89% ± 0.03%), glucuronic acid (14.07% ± 0.24%), galacturonic acid (2.12% ± 0.02%), and glucose (0.76% ± 0.02%). NAP exhibites water and oil retention capacities of 14.62 ± 0.25 g g−1 and 23.73 ± 0.85 g g−1, respectively. Furthermore, NAP demonstrates favorable moisture absorption and retention properties. The results show that NAP has a significantly stronger antioxidant effect, as demonstrated by its concentration‐dependent scavenging of ABTS, DPPH, and hydroxyl radicals.
