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

Wild edible truffles (namely, Terfezia leonis, Tirmania pinoyi, and T. nivea) were commercially obtained from Southern Algeria and methanolic extracts were prepared from these truffles. Their antioxidant and antiradical properties were studied by using five analytical methods: scavenging capacity on 1,1-diphenyl-2-picrylhydrazyl (DPPH·), 2,2'-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS·+), superoxide anion (O2·−) radicals, ferric reducing antioxidant power (FRAP), and ferricyanide/Prussian blue assay. Chemical constituents contributing to these activities were also investigated. T. leonis had the highest total phenolics, total carotenoids, and anthocyanin contents. At 2.6 mg/mL, scavenging effects on the DPPH· radical were 92.47%, 53.06%, and 41.34% for T. leonis, T. pinoyi, and T. nivea, respectively. T. leonis showed the most potent radical scavenging activities on DPPH·, ABTS·+, and O2·− radicals, with EC50 values of 1.08, 1.35, and 7.27 mg/mL, respectively. On the other hand, T. leonis exhibited the highest reductive capabilities. On the basis of the EC50 values, T. leonis had good antioxidant and antiradical properties. These results showed that methanolic extracts from these three truffles species had effective antioxidant and antiradical properties. Therefore, wild edible desert truffles could serve as an easily accessible item of food rich in natural antioxidants, as a possible food supplement, or even as a pharmaceutical agent.
