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

Cordyceps spp. (Clavicipitaceae) are well-known medicinal mushrooms used traditionally by indigenous and local communities throughout the world for the treatment of various ailments. Cordyceps robertsii has been used (as a part of awheto) by the Maori people as food and in traditional Maori tattoo, or ta-moko; and there is some evidence of traditional rongoa (medicinal) use. There is only limited scientific evidence of their bioactivity and potential for use in this area. This research aims to identify and quantify adenosine and cordycepin in C. robertsii from New Zealand by high-performance liquid chromatography (HPLC). We can report the presence of adenosine and that the level of this nucleoside in C. robertsii is at least comparable to that found in C. sinensis. The research also demonstrates that the presence of adenosine in C. robertsii varies, depending on factors including environment, climate, host organism, and nutrition. We can also report the absence of cordycepin in C. robertsii.
