The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.2 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00066 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.34 SJR: 0.274 SNIP: 0.41 CiteScore™:: 2.8 H-Index: 37

SINOPSIS

We investigated the sonication-assisted extraction (SAE) conditions of Tremella fuciformis polysaccharides. Single-factor experiments showed that the optimal sonication intensity was 6 W/cm2; the other SAE conditions were further optimized using response surface experimental design. A Box-Behnken experiment exhibited that the optimal SAE conditions were temperature, 85°C; ratio of liquid to solid, 46 mL/g; and sonication time, 2 hours. The maximal polysaccharide yield (8.95 g/100 g) was obtained under the optimal extraction conditions. Polysaccharides extracted by sonication or traditional hot water extraction (TWE) were further separated and purified using DEAE-Sepharose and Sephadex G-100 column chromatography. Polysaccharide fractions (SAE-1, SAE-2, TWE-1, and TWE-2) were obtained; their molecular weights were 9.85 × 104, 6.64 × 104, 4.75 × 105, and 2.81 × 105 Da, respectively. The total sugar content of SAE-1 and SAE-2 was lower and the protein and nucleic acid contents were higher than those of TWE-1 and TWE-2. In addition, SAE-1 and SAE-2 showed stronger Fe2+-chelating activities and superoxide radical scavenging activities than TWE-1 and TWE-2. This suggests that polysaccharides extracted by sonication possess high antioxidant activities.
