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

A number of synthetic antimicrobial agents have been developed to kill microorganisms effectively. However, drug resistance often occurs when these agents are used long-term. As a result, there has been a tremendous interest in the antimicrobial properties of plants and fungi. Ganoderma species are widely used, especially in Asia, for the treatment of chronic diseases such as cancer, hepatitis, bronchitis, asthma, and haemorrhoids. Many publications have also described the antimicrobial properties of compounds isolated from various polypores, including Ganoderma species. Nigeria has a rich biota of polypores, but the antimicrobial activity of these fungi has not been reported previously.
The antimicrobial activity of a new colossolactone, 23-hydroxycokissolactone E, and two known colossolactones isolated from Ganoderma colossum (Ganodermataceae) were tested against gram-positive and gram-negative bacteria. Fruiting bodies of G. colossum were collected from a dead log of Delonix regia (Fabaceae), Yaba College of Technology, Lagos, Nigeria. The polypore was morphologically determined as G. colossum by the truncate, ornamental, yellow basidiospore that is 11−17 × 7−11 cm in diameter. A voucher specimen accession K (M) 120802 was deposited in the herbarium at the Royal Botanic Garden, Kew, UK. Bioassay guided fractionation of compounds from a fungal sample was carried out using various chromatographic techniques. A ground sample was extracted with 100 mL of n-hexane: dichloromethane. The residue was reconstituted in methanol and subjected to column chromatography. Seventeen fractions obtained were fractionated using analytical thin layer chromatography (TLC). Chromatograms were inspected under UV light at 254 and 366 nm.
