Resumo: | Talinum fruticosum (L.) Juss. is popularly known as beldroega and bredo, its leaves are highly nutritious consumed as a substitute for spinach, presenting considerable concentrations of pro-vitamin A, calcium and iron. In addition, its leaves are used in the management of cardiovascular diseases, having immunomodulatory properties. In view of this, the objective of the study was to carry out the anatomical and histochemical characterization of the vegetative organs of T. fruticosum. For this, the usual methods in plant anatomy were used to make semi-permanent slides containing cross-sections of the root, stem, petiole and leaf blade and paradermal sections of the leaf blade of the species for analysis in optical microscopy light and polarized light. Histochemical tests were also performed using specific reagents in order to locate the metabolites in the fresh leaf blade through cross-sections. The main characters useful in identifying the species were: root with periderm with 4-5 cell layers and tetrarch vascular cylinder; stem with presence of angular collenchyma and druses in the parenchyma; petiole with open collateral vascular bundle and absence of collenchyma; amphistomatic leaf blade with paracytic stomata, midrib showing biconvex contour, uniseriate epidermis, annular collenchyma, mesophyll with 2-3 layers of palisade parenchyma and 5-6 layers of spongy parenchyma and presence of druses. In addition, through the histochemical study, the presence of lignin, druses of calcium oxalate and lipophilic compounds in the leaf blade was observed. The results presented are fundamental for the quality control of the plant drug and pharmacobotanical standardization of the studied species. |

Juss. é popularmente conhecida como beldroega e bredo, suas folhas são altamente nutritivas consumidas como substituta do espinafre, apresentando concentrações consideráveis de pró-vitamina A, cálcio e ferro. Além disso, suas folhas são utilizadas na gestão de doenças cardiovasculares, possuindo propriedades imunomoduladoras. Frente a isso, o objetivo do estudo foi realizar a caracterização anatômica e histoquímica dos órgãos vegetativos de T. fruticosum. Para isso, foram utilizados os métodos usuais em anatomia vegetal para confecção de lâminas semipermanentes contendo cortes transversais da raiz, caule, pecíolo e lâmina foliar e cortes paradérmicos da lâmina foliar da espécie para análise em microscopia óptica de luz e luz polarizada. Também foram realizados testes histoquímicos utilizando reagentes específicos afim de localizar os metabólitos na lâmina foliar fresca através de secções transversais. Os principais caracteres úteis na identificação da espécie foram: raiz com periderme apresentando 4-5 camadas de células e cilindro vascular tetrarca; caule com presença de colênquima angular e cristais do tipo drusa no parênquima; pecíolo com feixe vascular colateral aberto e ausência de colênquima; lâmina foliar anfiestomática com estômatos paracíticos, nervura central exibindo contorno biconvexo, epiderme unisseriada, colênquima anelar, mesofilo apresentando 2-3 camadas de parênquima paliçádico e 5-6 camadas de parênquima esponjoso e presença de drusas. Além disso, através do estudo histoquímico foi observada a presença de lignina, drusas de oxalato de cálcio e compostos lipofílicos na lâmina foliar. Os resultados apresentados são fundamentais para o controle de qualidade da droga vegetal e padronização farmacobotânica da espécie estudada.Universidade Estadual de Alagoas - Eduneal2023-04-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://diversitasjournal.com.br/diversitas_journal/article/view/247710.48017/dj.v8i2.2477Diversitas Journal; Vol. 8 No. 2 (2023): Através das lentes: a importância da biodiversidade para o equilíbrio ambiental; 865–873Diversitas Journal; Vol. 8 Núm. 2 (2023): Através das lentes: a importância da biodiversidade para o equilíbrio ambiental; 865–873Diversitas Journal; v. 8 n. 2 (2023): Através das lentes: a importância da biodiversidade para o equilíbrio ambiental; 865–8732525-521510.48017/dj.v8i2reponame:Diversitas Journalinstname:Universidade Estadual de Alagoas (UNEAL)instacron:UNEALporhttps://diversitasjournal.com.br/diversitas_journal/article/view/2477/2052Copyright (c) 2023 Marina Maria Barbosa de Oliveira, Cledson dos Santos Magalhães, Karina Perrelli Randauhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBarbosa de Oliveira, Marina Mariados Santos Magalhães, CledsonRandau, Karina Perrelli2023-11-09T21:54:57Zoai:ojs.diversitasjournal.com.br:article/2477Revistahttps://diversitasjournal.com.br/diversitas_journal/indexPUBhttps://www.e-publicacoes.uerj.br/index.php/muralinternacional/oairevistadiversitasjournal@gmail.com2525-52152525-5215opendoar:2023-11-09T21:54:57Diversitas Journal - Universidade Estadual de Alagoas (UNEAL)false |
