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

ABSTRAKT

Ganoderma P. Karst. (Ganodermatales, Basidiomycetes) is a cosmopolitan genus of wood decaying polypore mushrooms. In the Orient, Ganoderma species are used in folk medicine for treating several diseases, and some strains are commercially cultivated for medicinal use. The pharmacological effects of the Ganoderma species are attributable mainly to polysaccharides and triterpenoids. G. australe is a common species on the Santa Catarina Island (southern Brazil). Literature is scarce on the chemical composition of this species and also on studies relating substances produced by G. australe and their biological activity. A methanol extract from the basidioma of this species was obtained, which was partitioned successively with hexane, chloroform, and ethyl acetate. These extracts were fractionated using silica gel column chromatography. The fractions obtained in each column were grouped by analysis in thin layer chromatography. On the basis of thin-layer chromatography and antibacterial activity assay, some of the fractions were purified. Of these fractions, the following sterols were identified: 5α-ergost-7-en-3β-ol; 5α-ergost-7,22-dien-3β-ol; 5,8-epidioxi-5α,8α-ergost-6,22-dien-3β-ol; and the triterpenes applanoxidic acids A, C, F, and G. A preliminary study on the antibacterial activity of the extracts and chromatographic fractions obtained was carried out by the agar diffusion method. The extracts and some fractions were active mainly against the Gram-positive bacteria Bacillus cereus and Staphylococcus aureus.
