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

要約

The main objective of this study was to evaluate the antioxidant capacity of methanolic extracts from species of genus Phellinus: Ph. fastuosus, Ph. grenadensis, Ph. Merrillii, and Ph. Badius, in their respective polar fractions (aqueous) and nonpolar extracts (ethyl acetate), through tests of free-radical inactivation and hemolysis inhibition. The fungus species that gave the extract with the highest phenol content, total flavonoids, and antioxidant capacity [DPPH·, Trolox equivalents antioxidant capacity (TEAC), and hemolysis inhibition] was Ph. Merrillii, followed by Ph. fastuosus, Ph. Grenadensis, and Ph. Badius. The antioxidant capacities of the extracts, in descending order, were as follows: Ph. Merrillii (nonpolar), Ph. Fastuosus (nonpolar), Ph. Grenadensis (nonpolar), Ph. Fastuosus (polar), Ph. Merrillii (polar), Ph. Grenadensis (polar), Ph. Badius (nonpolar), and Ph. Badius (polar). Antioxidant capacity in the above Phellinus fungi species had EC50 values for DPPH inhibition of 0.45, 0.88, 1.31, 1.89, 2.14, 2.22, 3.42, and 6.00 mg/mL, respectively; TEAC values of 10400.29, 7635.53, 4855.05, 4415.39, 4041.68, 2989.2, 1937.7, and 842.42 µmol TE/g, respectively; and hemolysis inhibition values of 72.83, 66.95, 50.87, 50.28, 48.5, 42.82, 42.37, and 37.91%, respectively. In general, the fungus extract with the highest antioxidant capacity was the nonpolar fraction of Ph. Merrillii. The Phellinus species studied represent potential natural sources of bioactive compounds with antioxidant activity.
