Caracterização e descrição da estrutura anatômica do lenho de seis espécies arbóreas com potencial medicinal

Abstract

RESUMO:A caracterização morfoanatômica e a correta identificação das plantas medicinais são fundamentais para o controle de qualidade dos fitoterápicos. No presente trabalho é caracterizada a anatomia do lenho visando à identificação de seis espécies arbóreas com potencial medicinal. As amostras do lenho foram extraídas por método não destrutivo do tronco das árvores das espécies desenvolvidas em áreas de preservação. Em laboratório as amostras do lenho foram processadas para análises microscópicas do lenho, aplicando as metodologias para estudos de anatomia. Os resultados mostraram que o parênquima axial foi o parâmetro anatômico mais efetivo para a distinção das espécies através da análise do seu lenho. No trabalho discute-se a importância da aplicação da anatomia do lenho como ferramenta na identificação de espécies arbóreas medicinais.

The morphoanatomical characterization and the correct identification of medicinal plants are fundamental for the quality control of phytotherapics. In the present work, wood anatomy was characterized in order to identify six tree species with medicinal potential. Wood samples were collected through a non-destructive method from the trunk of trees developed in conservation areas. In the laboratory, wood samples were processed for microscopic analysis by applying the methods for anatomical studies. Axial parenchyma was the most effective anatomical parameter to distinguish species through wood analysis. In this work, the importance of wood anatomy as a tool for the identification of medicinal tree species was discussed.

Potential of spalting moderate value wood species in Peru

“…Ktze., and Cariniana estrellensis (Raddi) O. Ktze., are known to have antimicrobial compounds in the wood (Cury and Tomazello-Filho 2011).…”

Anatomical characterization of the vegetative organs of three Solanum sp. L. Juss. (Solanaceae) species popularly known as medicinal

“…S. americanum, also called aguaraguá, is used as medicine by the population in the treatment of injuries caused by Leishmania sp. (Trypanosomatidae) [7] , cough, and infection by protozoa [2] .…”

“…In addition to the issue of production of toxic substances, the correct botanical identification of medicinal species is fundamental to develop pharmacological research, as well as to ensure the genetic conservation and maintenance of biodiversity [2] and correct and safe use by the population.…”

A phylogenetic and functional perspective on the origin and evolutionary shifts of growth ring anatomical markers in seed plants

“…This type may be understood as a change in which the parenchyma becomes less dense in the latewood and thus could be included in the category described above (Section III.5b); however its peculiarities lead us to separate it into its own category. Examples of families with this special type of fibre zone are Chrysobalanaceae (Détienne & Jacquet, 1983;Mainieri & Chimelo, 1989), Leguminosae (Freitas, 1963;Détienne & Jacquet 1983;Mainieri & Chimelo, 1989;Cop, 2010), Lecythidaceae (Détienne & Jacquet, 1983;Fedalto et al, 1989;Mainieri & Chimelo, 1989;Miller & Détienne, 2001;Pons & Franceschi, 2007;Cury & Tomazello-Filho, 2011), Moraceae (Freitas, 1963;Détienne & Jacquet, 1983;ter Welle, Koek-Noorman & Topper, 1986a), and Sapotaceae (Kukachka, 1981a;Détienne & Jacquet, 1983;Mainieri & Chimelo, 1989;Miller & Détienne, 2001). In some cases, this fibre zone may lack vessels, as in Manilkara elata (Allemão ex Miq.)…”
