The chemical structures determined by MS and NMR were 4-[2-formyl-5-(hydroxymethyl)-1H-pyrrol-1-yl] butanoic acid (compound I), 4-[2-formyl-5-(hydroxymethyl)-1H-pyrrol-1-yl] butanamide (compound II), and 5-(hydroxymethyl)-1H-pyrrole-2-carboxaldehyde (compound III). Compound I was found to be the major component, followed by compound II, and compound III was the minor component. The dry powder of Basidiomycetes-X contained approximately 825 \u03bcg g\u22121 compound I and 484 \u03bcg g\u22121 compound II. Compound II was found to be a novel pyrrole aldehyde homologue not previously reported and thus is a specific component of this mushroom.<\/jats:p>","DOI":"10.3390\/molecules25214879","type":"journal-article","created":{"date-parts":[[2020,10,23]],"date-time":"2020-10-23T02:01:42Z","timestamp":1603418502000},"page":"4879","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Identification of a Novel Pyrrole Alkaloid from the Edible Mushroom Basidiomycetes-X (Echigoshirayukidake)"],"prefix":"10.3390","volume":"25","author":[{"given":"Toshio","family":"Sakamoto","sequence":"first","affiliation":[{"name":"School of Biological Science and Technology, College of Science and Engineering, Kanazawa University, Kakuma, Kanazawa 920-1192, Japan"},{"name":"Division of Natural System, Graduate School of Natural Science and Technology, Kanazawa University, Kakuma, Kanazawa 920-1192, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ayaka","family":"Nishida","sequence":"additional","affiliation":[{"name":"Division of Natural System, Graduate School of Natural Science and Technology, Kanazawa University, Kakuma, Kanazawa 920-1192, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naoki","family":"Wada","sequence":"additional","affiliation":[{"name":"School of Biological Science and Technology, College of Science and Engineering, Kanazawa University, Kakuma, Kanazawa 920-1192, Japan"},{"name":"Division of Natural System, Graduate School of Natural Science and Technology, Kanazawa University, Kakuma, Kanazawa 920-1192, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yutaka","family":"Nakamura","sequence":"additional","affiliation":[{"name":"Faculty of Applied Life Sciences, Niigata University of Pharmacy and Applied Life Sciences, Higashijima, Akiha-ku, Niigata 956-8603, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shinji","family":"Sato","sequence":"additional","affiliation":[{"name":"Faculty of Applied Life Sciences, Niigata University of Pharmacy and Applied Life Sciences, Higashijima, Akiha-ku, Niigata 956-8603, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tetsuya","family":"Konishi","sequence":"additional","affiliation":[{"name":"Faculty of Applied Life Sciences, Niigata University of Pharmacy and Applied Life Sciences, Higashijima, Akiha-ku, Niigata 956-8603, Japan"},{"name":"Office HALD Food Function Research, Inc., Yuzawa, Niigata 949-6102, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seiichi","family":"Matsugo","sequence":"additional","affiliation":[{"name":"Division of Natural System, Graduate School of Natural Science and Technology, Kanazawa University, Kakuma, Kanazawa 920-1192, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"209","DOI":"10.1002\/jsfa.5960","article-title":"A review of chemical composition and nutritional value of wild-growing and cultivated mushrooms","volume":"93","year":"2013","journal-title":"J.
