Proportion of different truxilline forms present in cocaine serves as its geographical, manufacture, and storage \u201cfingerprint\u201d; thus, the quantitative determination of truxilline content represents one of the powerful methods of analysis and characterization of cocaine samples. Contrary to the statements repeatedly presented in the literature, namely, that there exist exactly 11 truxillines and that every single truxilline is diastereomer of any other, here we show that,\u00a0in fact, a total of 15 truxillines exist, which can be divided in two structurally isomeric groups\u2014five mutually diastereomeric truxillates and 10 mutually diastereomeric truxinates.<\/jats:p>","DOI":"10.1002\/chir.23680","type":"journal-article","created":{"date-parts":[[2024,5,21]],"date-time":"2024-05-21T15:18:19Z","timestamp":1716304699000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Counting the truxillines\u201411 or more, the question is now"],"prefix":"10.1002","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7139-0881","authenticated-orcid":false,"given":"Tomislav","family":"Portada","sequence":"first","affiliation":[{"name":"Laboratory for the Computational Design and Synthesis of Functional Materials, Division of Organic Chemistry and Biochemistry Ru\u0111er Bo\u0161kovi\u0107 Institute  Zagreb Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0178-5992","authenticated-orcid":false,"given":"Zlatko","family":"Brklja\u010da","sequence":"additional","affiliation":[{"name":"Division of Organic Chemistry and Biochemistry Ru\u0111er Bo\u0161kovi\u0107 Institute  Zagreb Croatia"},{"name":"Selvita d. o. o.
