Resumo: | The morphoanatomical description of vegetable species, for medical purpose, is necessary to foreground the analyses of quality control in the pharmacognostic laboratories. The objective of this study was to analyze two Lamiaceae species known as “false-boldus” (Plectranthus barbatus and P. grandis), characterizing and quantifying the trichomes present in their leaves and stems. For the morphoanatomical analyses transverse sections of the leaves, petiole, and stem were prepared, using common techniques of plant morphology and anatomy for the preparation of semi-permanent slides, stained with astra blue and safranin. Analyses revealed that the leaves of both species are morphologically similar, but differ with regard to dimensions. The glandular trichomes found were: peltate, short-capitate and long-capitate; and tectors (simple uniseriate with two or more cells in the base). With few exceptions, all five trichomes types were observed in the leaves, petiole and stem, and the averages obtained for P. grandis significantly were superior to the ones found in the P. barbatus organs, except for the trichome simple tector which was more abundant in the stem of the second specie. |

Para as análises morfoanatômicas foram preparadas seções transversais do limbo, pecíolo e entrenós do caule, utilizando-se de técnicas usuais de morfologia e anatomia vegetal para a preparação de laminário semipermanente, tendo como corantes o azul de astra e a safranina. As análises revelaram que as folhas de ambas as espécies são morfologicamente semelhantes, mas diferindo quanto às dimensões do limbo. Os tipos de tricomas glandulares encontrados foram: peltado, captado-longo e captado-curto; e tectores: simples unisseriados com duas ou mais células na base. Com algumas exceções, todos os cinco tipos de tricomas foram observados no limbo, pecíolo e entrenós do caule, tendo P. grandis números médios significativamente superiores aos encontradas nos órgãos de P. barbatus, com exceção do tricoma tector simples, mais abundante no caule da segunda espécie.Universidade Estadual De Maringá2007-12-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/44510.4025/actascibiolsci.v29i2.445Acta Scientiarum.
