CarquejaMorphology Anatomy Quality control A B S T R A C TBaccharis glaziovii Baker, Asteraceae, also known as carqueja or carqueja-arbustinho, is a native shrub of Brazil that reaches 0.5-2.5 m in height. It is a dioecious species that blossoms from September to December. This species has cladodes, which are winged stems that belong to the "carquejas" and are widely used indiscriminately by the population due to their gastric and diuretic properties. Carquejas are included in section Caulopterae and are difficult to identify even for taxonomists or Baccharis specialists. In the present study, a morpho-anatomical (cladodes and leaves) analysis of the medicinal plant was undertaken to improve its identification and add to the knowledge of section Caulopterae. Fragments of cladodes and leaves were collected and prepared in accordance with standard optical and scanning electron microscopy techniques. The morpho-anatomical characteristics found in B. glaziovii, include three-winged stems showing wings in a regular arrangement around the stem axis, short and petiolate leaves, flagelliform and simple non-glandular trichomes, concave-convex midrib, petioles with a concave shape and a slight projection on the adaxial face and convex with three projections on the abaxial surface, and calcium oxalate crystals in the form of raphides, styloids and pyramidal in the perimedullary region of the cladode, when evaluated as a whole, provide support for the quality control.

“…However, the presence of crystals in the tribes Astereae, Cardueae, Heliantheae and Inuleae of the family Asteraceae was shown by some recent studies (Meric and Dane 2004, Meric 2008, 2009a, b, Kartal 2016). In the case of the tribe Astereae, which includes S. chilensis, several types of calcium oxalate crystals were found, such as styloids, prisms, raphides, druses and crystal sand (Cortadi et al 1999, Petenatti et al 2007, Meric 2008, 2009a, Budel and Duarte 2009, 2010, Jasinski et al 2014, Budel et al 2015. Therefore, the type, and presence or absence of crystals may be represented as a taxonomic character (Lersten andHorner 2000, Horner et al 2012).…”

Solidago chilensis Meyen, belonging to the family Asteraceae, is a plant native to South America and the only representative of the genus in Brazil. This species is popularly known as "arnica" and is used to treat bruises, muscle pain and inflammation. The objective of this work was to contribute to the pharmacognostic standardization of S. chilensis. Cross-sections were obtained, by freehand, for microscopic analysis of root, stem and leaf; for these parts of the plant maceration was also performed according to the method of Jeffrey. For the leaf were still made paradermal sections, scanning electron microscopy analysis, phytochemical and histochemical tests. Thus, it was determined anatomical features useful for diagnosis of the species which, together with identification of the chemical compounds and its histolocalization, provides support to their quality control.

Tricomas glandulares são encontrados isolados, entretanto, frequentemente podem aparecer em tufos e em depressão na epiderme na espécie avaliada.…”

RESUMO:Baccharis rufescens Spreng. var. tenuifolia (DC.) Baker pertence à família Asteraceae e é usada na medicina tradicional como estomáquico e hepatoprotetor. Um estudo fitoquímico mostrou a presença de flavonoides e triterpenos, sendo que os extratos clorofórmico e metanólico de folhas apresentaram-se ativos no bioensaio de toxicidade sobre Artemia salina Leach. Além disso, extratos clorofórmicos evidenciaram a presença de peróxidos, sugerindo sua aplicação no tratamento da malária (Schenkel at al., 2002;Montanher et al., 2002;Moreira et al., 2003). Considerando a importância farmacológica de B. rufescens var. tenuifolia, o presente trabalho objetivou o estudo morfoanatômico e histoquímico do caule e da folha dessa espécie, a fim de fornecer subsídios farmacognósticos para o controle de qualidade. O material botânico foi submetido às técnicas usuais empregadas na microscopia de luz e microscopia eletrônica de varredura. Folha anfiestomática, presença de estômatos anomocíticos, tricomas glandulares capitados bisseriados, tricomas tectores flageliformes simples unisseriados, dutos secretores associados ao floema, calota de fibras perivasculares e cristais de oxalato de cálcio do tipo estiloide e prismático na região medular do caule foram as principais características observadas que auxiliam na identificação do táxon.Palavras-chave: Asteraceae, Baccharis, Baccharis rufescens Spreng. var. tenuifolia (DC.) Baker, farmacognosia ABSTRACT: Baccharis rufescens Spreng. var. tenuifolia (DC.) Baker: contribution to the pharmacognostic study. Baccharis rufescens Spreng. var. tenuifolia (DC.) Baker belongs to the Asteraceae family. It is used for liver and stomach problems in traditional medicine. Previous phytochemical data reported flavonoid and triterpene contents. Chloroform and methanol extracts of the leaves showed activity in the bioassay of brine shrimp. Chloroform extracts showed the presence of peroxides that can be used to treat malaria (Schenkel et al., 2002;Montanher et al., 2002;Moreira et al., 2003). Considering the pharmacological importance of B. rufescens var. tenuifolia, the purpose of this paper was to perform the anatomical analysis of aerial vegetative parts of Baccharis rufescens var. tenuifolia in order to provide pharmacognostic data for quality control. The plant material was studied by the usual methods of light and scanning electron microscopy. Amphistomatic leaves, anomocytic stomata, biseriate capitate glandular trichomes, uniseriate simple flagelliform non-glandular trichomes, secretory ducts associated to the phloem, perivascular fiber cap, calcium oxalate as prismatic and styloid crystals in the pith of the stem were reported as the mainly anatomical data for B. rufescens var. tenuifolia.Ouvir Ler foneticamente
