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

RESUMO

A preliminary biological investigation of the dry basidiomata of strain C-142-c of Pleurotus eryngii has shown significant antioxidant activity. Two different polysaccharides (PEPS-A1 and PEPS-A2) were isolated from the cultivated edible mushroom, P. eryngii C-142-c strain. Based on acid hydrolysis, methylation analysis, and nuclear magnetic resonance experiments (1H, 13C, distortionless enhancement by polarization transfer, double quantum filtered correlation spectroscopy, total correlation spectroscopy, nuclear Overhauser effect spectroscopy, heteronuclear single-quantum correlation spectroscopy, and heteronuclear multiple-bond correlation spectroscopy), the structures of the repeating unit of PEPS-A1 and PEPS-A2 were established as follows: (l)PEPS-Al (α-glucan): [→6)-α-D-Glcp-(1→6)-α-D-Glcp-(l→]n; and (2) PEPS-A2 (β-glucan): [→6)-β-D-Glcp-(1→6)-β-D-Glcp-(l→]n. The antioxidant activity of PEPS-A1 and PEPS-A2 was evaluated as hydroxyl radical scavenging activity. PEPS-A1 and PEPS-A2 showed SC50 values of 400 μg/mL and 122 μg/mL, respectively, suggesting their possible use as a dietary supplement in functional foods. The polysaccharides were tested for their activity on cell viability using a colorectal adenocarcinoma cell line (HT-29). Both polysaccharides affected cell viability after 48 and 72 hours of treatment, inducing the death of 50% of HT-29 cells between 0.25 and 1 μg/mL and between 0.5 and 1 μg/mL, respectively, for PEPS-A1 and PEPS-A2. These results are promising for future applications of these mushroom-derived polysaccharides as antioxidants and antitumor agents.
