Resumo: | Paullinia is a monophyletic genus of lianas with a neotropical distribution, encompassing approximately 220 species. In Brazil, there are 102 species occurring mainly in the phytogeographic domains of the Atlantic Forest and Amazonia. The species of this genus have diverse uses as psychotropics, bactericides, antioxidants, fish poisons, stimulants and for ritualistic purposes. The genus is nevertheless insufficiently studied from the anatomical and histochemical standpoints. In the present study, morphoanatomical and histochemical investigations were made of the leaves of Paullinia dasygonia Radlk., P. micrantha Cambess. and P. trigonia Vell. The species studied have very similar leaf characters which makes their identification difficult. The leaves have dorsiventral structure, collateral vascular bundles and both non glandular and glandular trichomes which vary in the species as regards shape, length and distribution. The glandular trichomes have neutral polysaccharides and phenolic compounds. In addition, laticifers were observed containing lipid droplets, alkaloids, proteins and phenolic compounds in diverse regions of the leaf. Saponins, which are characteristic of the family, were observed in the secretory trichomes and generally in the mesophyll and midrib. The results obtained provide evidence justifying further pharmacological investigation of these three species, as well as others in the genus. |

No Brasil, existem 102 espécies ocorrendo principalmente nos domínios fitogeográficos da Mata Atlântica e Amazônia. As espécies deste gênero possuem diversos usos como psicotrópicos, bactericidas, antioxidantes, venenos de peixes, estimulantes e para fins ritualísticos. O gênero é, no entanto, pouco estudado do ponto de vista anatômico e histoquímico. No presente estudo, foram feitas investigações morfoanatômicas e histoquímicas das folhas de Paullinia dasygonia Radlk., P. micrantha Cambess. e P. trigonia Vell. As espécies estudadas possuem caracteres foliares muito semelhantes, o que dificulta sua identificação. As folhas apresentam estrutura dorsiventral, apresentam feixes vasculares colaterais e tricomas tectores e glandulares que variam nas espécies quanto à forma, comprimento e distribuição. Os tricomas glandulares possuem polissacarídeos neutros e compostos fenólicos. Além disso, foram observados laticíferos contendo gotículas lipídicas, alcalóides, proteínas e compostos fenólicos em diversas regiões da folha. As saponinas, características da família, foram observadas nos tricomas secretores e geralmente no mesofilo e nervura central. Os resultados obtidos fornecem evidências que justificam a investigação farmacológica dessas três espécies, bem como outras do gênero.Centro de Inovação em Biodiversidade e Saúde - Farmanguinhos/Fiocruz2023-12-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://revistafitos.far.fiocruz.br/index.php/revista-fitos/article/view/150110.32712/2446-4775.2023.1501Revista Fitos; Vol. 17 No. 4 (2023); 479-489Revista Fitos; Vol. 17 Núm. 4 (2023); 479-489Revista Fitos; v. 17 n. 4 (2023); 479-4892446-47751808-9569reponame:Revista Fitosinstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZenghttps://revistafitos.far.fiocruz.br/index.php/revista-fitos/article/view/1501/1413https://revistafitos.far.fiocruz.br/index.php/revista-fitos/article/view/1501/1414Copyright (c) 2023 Revista Fitoshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess Pimentel, Rafael Ribeiro Rocha, Joecildo FranciscoArruda , Rosani do Carmo de OliveiraSomner , Genise Vieira2024-01-24T15:18:42Zoai:ojs.revistafitos.far.fiocruz.br:article/1501Revistahttps://revistafitos.far.fiocruz.br/index.php/revista-fitos/PUBhttp://revistafitos.far.fiocruz.br/index.php/revista-fitos/oairevistafitos@far.fiocruz.br || eugenio.telles@far.fiocruz.br2446-47752446-4775opendoar:2024-01-24T15:18:42Revista Fitos - Fundação Oswaldo Cruz (FIOCRUZ)false |
