“…Analogous glandular trichomes were found in P. regnelli (Pessini et al, ), P. mikanianum (Kunth) Steud (Duarte & Siebenrock, ), Piper lepturum var. lepturum (Machado et al, ) and P. amalago L. (Santos et al, ). Multicellular and uniseriate nonglandular trichomes, either short or long, shaped by about five cells, with acute apical cells have been mentioned in relation to several species of Piper (Duarte & Siebenrock, ; Gogosz et al, ; Machado et al, ; Raman et al, 2014; Santos et al, ).…”

“…The stomata were tetracytic and actinocytic types ( Figure 1c) and they were only present on the abaxial face ( Figure 1c). Tetracytic stomata are frequent in Piper (Gogosz et al, 2012;Machado et al, 2015;Santos, Franco, Amano, Messias-Reason, & Budel, 2015). However, other types can be found such as staurocytic (Souza et al, 2009), cyclocytic (Albiero, Paoli, Souza, & Mourão, 2005), as well as anisocytic, anomocytic, polycytic, paracytic, and amphicyclic (Raman, Galal, & Khan, 2012).…”

“…Piperaceae Giseke comprises 2,750 species distributed in 13 genera (Mabberley, 2008) that have a relatively complex taxonomy (Machado, Pereira, Santos, Costa, & Guimarães, 2015). Piper L. is the most representative genus of Piperaceae, with 2,000 species spread in the Neotropics (Jaramillo et al, 2008).…”

Piper solmsianum C.DC., which is popularly known as pariparoba, is a shrub that measures 1-3 m in height and it inhabits areas with wet tropical soils. The objective of this study was to analyze the leaf and stem anatomy using light microscopy, scanning electron micrographs, and energy-dispersive X-ray spectroscopy in order to provide information for species identification. The anatomical profile showed the following main microscopic markers: hypostomatic leaf; hypodermis layer on both sides; pearl glands; biconvex midrib shape; five collateral vascular bundles in open arc with the central bundle larger than the others; circular stem shape; collateral vascular bundles arranged in two rings; sinuous sclerenchymatic sheath in the pith; secretory idioblasts; and starch grains in the mesophyll, in the ground parenchyma of the midrib, petiole, and in the stem; and six morphotypes of calcium oxalate crystals (styloids, cuneiform, tabular crystal rosettes, cuneiform crystal rosettes, elongated square dipyramids, as well as very elongated square dipyramids).

“…Para os cristais, deverão ser considerados como marcadores anatômicos os morfotipos cristalinos citados como específicos para as duas espécies . Os estômatos, por sua vez, não têm valor na delimitação taxonômica de Piperaceae devido à complexidade e variação morfológica que apresentam no grupo (Gogosz et al 2012;Machado et al 2015).…”

RESUMOPiper arboreum Aubl. var. arboreum e P. tuberculatum Jacq. (Piperaceae), conhecidas como pimenta-longa, são comercializadas como produtos tradicionais fitoterápicos e, frequentemente, identificadas erroneamente, não havendo relatos sobre controle de qualidade dessas espécies. O objetivo do trabalho foi preparar e caracterizar drogas vegetais foliares e caulinares dessas espécies para estabelecer-lhes parâmetros de autenticidade botânica e grau de pureza para o controle de qualidade. Foram utilizados métodos padrões para o preparo e análises estrutural e físico-química das drogas vegetais. São caracteres diagnósticos macroscópicos para distinguir as drogas vegetais íntegras: tamanho, forma, cor, sabor, textura, características da superfície de fratura e da secção transversal e os padrões de venação foliar. São caracteres diagnósticos para distinguir as drogas vegetais pulverizadas: padrões de cutícula e cera epicuticular, tipos de tricoma e espessamento parietal dos elementos traqueais e a forma do hilo dos grãos de amido. Emergências são marcadores morfológicos chave para as drogas vegetais de P. tuberculatum. Os valores dos parâmetros físico-químicos foram similares nas drogas vegetais das espécies, exceto o de cinzas ácido-insolúveis que foi maior nas drogas vegetais caulinares de P. arboreum var. arboreum. As maiores concentrações de metais ocorreram nas drogas vegetais de P. arboreum var. arboreum. As concentrações mais elevadas foram de Al, Cu, Mn e V e as mais baixas de Cd, Co e Hg. Os resultados obtidos poderão ser utilizados como parâmetros de controle de qualidade para as drogas vegetais de ambas as espécies. PALAVRAS-CHAVE: Pimenta-longa, Produtos tradicionais fitoterápicos, Farmacognosia, Metais tóxicos, ICP-OES. Pharmacognostical characterization of Piper arboreum var. arboreum and P. tuberculatum (Piperaceae)ABSTRACT Piper arboreum Aubl. var. arboreum and P. tuberculatum Jacq. (Piperaceae), both known as "pimenta-longa", are frequently misidentified. Despite the fact that both species are sold as traditional phytotherapeutic products, there are no reports on their quality control. The aim of this study was to prepare and characterize leaf and stem herbal drugs of both species using standard methods aiming to establish parameters for botanical authentication and purity degree for their quality control. Size, shape, color, taste, texture, fracture surface and transection characteristics, and leaf venation patterns are macroscopic diagnostic characters useful to distinguish the herbal drugs when they are not powdered. The following characters are useful for diagnostic purposes of the powdered herbal drugs: cuticular and epicuticular wax patterns, types of trichomes, and wall thickening of the tracheary elements, and shape of the hilum of the starch grains. Emergences are key morphological markers for P. tuberculatum herbal drugs. Physicochemical parameter values were similar in herbal drugs of both species, except acid-insoluble ash value which was higher in the P. arboreum var. arboreum stem her...

“…Autores do século XV foram pioneiros no uso dos dados anatômicos para o reconhecimento das plantas, dentre eles Grew (1682) e Malpighi (1687). A literatura contém relatos morfoanatômicos sobre Piper que dão respaldo à taxonomia do gênero (Albiero et al 2005a, 2005b, Gogosz et al 2012, Machado et al 2015. Por outro lado, pesquisas relacionadas à morfologia interna, não raro, fornecem subsídios aos trabalhos taxonômicos (Carlquist 1961).…”

RESUMO -Descrições anatômicas de Piper arboreum Aubl. var. arboreum e P. tuberculatum Jacq. var. tuberculatum que ocorrem na Floresta Ombrófi la Densa da Tijuca são apresentadas neste estudo. O material foi examinado de acordo com as técnicas usuais da anatomia. Importantes diferenças foram detectadas entre os táxons. Piper arboreum possui bainha sulcada e contém espaços intercelulares conspícuos, lâmina foliar com hipoderme biestratifi cada, parênquima paliçádico uniestratifi cado e nervura principal côncavo-convexa. Piper tuberculatum possui bainha de disposição circinada, com espaços intercelulares pequenos, lâmina foliar com hipoderme uniestratifi cada, parênquima paliçádico biestratifi cado e nervura principal biconvexa. As análises anatômicas corroboram em considerar os referidos táxons como distintos.Palavras-chave: anatomia foliar, fl ora, Piperaceae, taxonomia ABSTRACT -Comparative morphoanatomy of Piper arboreum Aubl. var. arboreum and Piper tuberculatum Jacq. var. tuberculatum leaves. Anatomical descriptions of Piper arboreum Aubl. var. arboreum and P. tuberculatum Jacq. var. tuberculatum that are found in Dense Rainforest in Tijuca are presented in this study. The material was examined according with the usual anatomical techniques. Important diff erences between the taxa were observed. In P. arboreum the sheath is furrowed and contained conspicuous intercellular spaces, the leaf blade contains biestratifi ed hypodermis, unistratifi ed palisade parenchyma, and a concave-convex midrib. P. tuberculatum presents circinate sheath with small intercellular spaces, the leaf blade has unistratifi ed hypodermis, biestratifi ed palisade parenchyma and a convex midrib. The anatomical analysis corroborate the delimitation of the two taxa as distinct.
