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

摘要

Fermentation concentrate of Hericium caput-medusae (HFC) was used in this study and two different molecular weight oligosaccharides (HFCO1, HFCO2) were obtained by dialysis methods. Furthermore, DEAE Sepharose Fast Flow and Sephadex G-25 column chromatography were used to obtain the two purified components (HFCO1-1, HFCO2-1). The two components were partially characterized, and analysis of monosaccharide composition through Fourier-transform infrared spectroscopy was performed. The sugar-containing components in HFC were mainly neutral oligosaccharides, and the monosaccharide composition was mainly glucose, with the configuration of α-pyranose. Their chemical and cellular antioxidant activities were compared, and the results showed that antioxidant activities of HFCO2 were higher than HFCO2-1 and antioxidant activities of crude oligosaccharides were higher than those of neutral oligosaccharides. By both in vitro and in vivo studies of scavenging activities toward the free radicals and increasing the activity of antioxidant enzymes in cells, HFCO2 and HFCO2-1 could suppress H2O2-induced reduction in cell viability.
