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

SINOPSIS

This research studies the influence of substrate on the antioxidant activity of alcohol extracts of Paecilomyces hepiali. We used corn, rice, millet, and peas as substrates. Antioxidant activity was measured with the DPPH radical scavenging method. Concentrations of extracts (6.25, 3.12, 1.56, 0.78, and 0.39 mg/mL) were applied in all evaluations. Overall antioxidant activity was expressed as the concentration of substrate that decreased DPPH radical levels by 50% (IC50DPPH) for 7 methanol and 7 ethanol extracts. A comparison of IC50DPPH allowed us to conclude that the methanol extracts are more active in scavenging stable DPPH radicals than are the ethanol extracts. The substrate with antioxidant properties most suitable for cultivation of P. hepiali was rice supplemented with non-defatted soy flour. The extract most effective in scavenging stable radicals was the methanol extract of sample 4 (IC50DPPH = 2.33 mg/mL) cultivated on rice with nondefatted soy flour. The methanol extract of sample 7 cultivated on peas was less effective (IC50DPPH = 11.50 mg/mL). By crystallizing these extracts, we managed to obtain sufficient quantities of 6 samples in a solid state, for which infrared spectra were measured and confirmed the presence of amino acids in the extracts.
