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

ABSTRACT

This study was conducted to evaluate the mycochemical composition and antiglycemic and antioxidant activities of Ganoderma neo-japonicum hot aqueous extracts, prepared at different boiling durations, and polysaccharides isolated from them. Ground basidiocarps of G. neo-japonicum were double-boiled at 100°C for 0.5, 3, or 4 hours, and the antiglycemic activity was assessed by α-amylase and α-glucosidase enzyme inhibition assays. The antioxidant capacity of the crude hot aqueous extracts (AE-1, AE-2, AE-3) was assessed by DPPH and ABTS radical scavenging and ferric-reducing antioxidant power assays. The total phenolics, protein, and sugar in the crude extracts were also determined. The hot aqueous extract (AE-3) containing a significant amount of total sugar and having enhanced antiglycemic and antioxidant activities was selected for polysaccharide isolation. The isolated crude polysaccharide was separated and purified using diethylaminoethyl-cellulose-52 and Sepharose 6B column chromatography. Fourier transform infrared spectroscopy studies of the purified polysaccharide fraction (PF) showed the presence of typical bands corresponding to polysaccharides. The estimated β-glucan concentration in the PF was 39.26%. In general, the PF exhibited significantly lower antioxidant activity than AE-3. Nevertheless, its potency in inhibiting carbohydratehydrolyzing enzymes may have potential in the management of diabetes mellitus.
