        Anthraquinone as emerging contaminant: technological, toxicological, regulatory and analytical aspects

        Valduga Alice Teresa,Gonçalves Itamar Luís,Saorin Puton Bruna Maria,de Lima Hennig Bruna,Sousa de Brito Edy 한국독성학회 2024 Toxicological Research Vol.40 No.1

        Anthraquinone (anthracene-9,10-dione) is a multifaceted chemical used in the paper industry, in the production of synthetic dyes, in crop protection against birds and is released from fossil fuels. Additionally, the anthraquinone scaffold, when substituted with sugars and hydroxyl groups is found in plants as metabolites. Because of these multiple applications, it is produced on a large scale worldwide. However, its toxicological aspects have gained interest, due to the low limits in the foods defined by legislation. Worrying levels of anthracene-9,10-dione have been detected in wastewater, atmospheric air, soil, food packaging and more recently, in actual foodstuffs. Recent investigations aiming to identify the anthracene-9,10-dione contamination sources in teas highlighted the packaging, leaves processing, anthracene metabolism, reactions between tea constituents and deposition from the environment. In this context, this review seeks to highlight the uses, sources, biological effects, analytical and regulatory aspects of anthracene-9,10-dione.

        Trends in Ilex paraguariensis researches: a bibliometric analysis

        Gonçalves Itamar Luís,Valduga Alice Teresa 한국식품연구원 2023 Journal of Ethnic Foods Vol.10 No.25

        Background Yerba-mate (Ilex paraguariensis St. Hil) is a perennial South American plant widely investigated due to its effects on human health and chemical composition. Due to the presence of high levels of methylxanthines, phenolic compounds and saponins, yerba-mate is attractive under chemical and pharmacological aspects. Yerba-mate leaves are processed for the consumption of traditional beverages with a social, cultural and economic importance. Results Totally, 839 publications on the topic yerba-mate were identified in the Web of Science database, accumulating 15,365 citations with an h-index = 55. A text-based analysis of the abstract articles identified three main research fields: plant science, chemical composition and biological effects. These publications were distributed in 378 journals and involved the efforts of 3169 authors distributed in 48 countries and 681 organizations. Conclusion The results reported here are a first graphic overview of the yerba-mate scientific production considering the research areas, journals citation coupling and cooperation among countries, organizations and authors.
