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

Flammulin, an antitumor substance, was purified from the aqueous extract of basidiomes of Flammulina velutipes (Curt.: Fr.) P.Karst. It was judged homogenous by SDS-polyacrylamide gel electrophoresis. The purification procedure included ammonium sulfate precipitation, ethanol fractionation, DEAE-Sephadex anion-exchange chromatography, crystallization, and recrystallization. Flammulin was crystallized with microdialysis against a polyethylene glycol sodium phosphate buffer. The crystals were rhombohedron-shaped and easy to melt when the crystallization conditions were changed. With a molecular mass of 23,700, flammulin was characterized by its lack of Met. Amino acid composition analysis showed that the numbers of acidic amino acids are more than that of basic amino acids, but the isoelectric point detected by analytical isoelectric focusing was at pH8.9.
