Análise morfoanatômica comparativa de duas espécies de carqueja: Baccharis microcephala DC. e B. trimera (Less.) DC., Asteraceae BJPS
Budel,Jane Manfron; Duarte,Márcia do Rocio.
A identificação de espécies de Baccharis que são constituídas de cladódios, ou seja, caules alados, apresenta dificuldades até mesmo para especialistas em taxonomia vegetal. Baccharis microcephala e B. trimera pertencem ao grupo Trimera e são conhecidas vulgarmente como carquejas. Na medicina popular, é comum o uso de espécies aladas para a aplicação terapêutica como diurético, hepatoprotetor e digestivo. Baccharis trimera consta na F. Bras. IV e possui atividades antiinflamatória, analgésica, bacteriostática, bactericida e antidiabética. As espécies B. trimera e B. microcephala são freqüentemente confundidas e utilizadas pela população para as mesmas finalidades terapêuticas. Objetivou-se estudar a morfologia externa e a anatomia dos cladódios dessas...

Anatomical characters of the medicinal leaf and stem of Gymnanthemum amygdalinum (Delile) Sch.Bip. ex Walp. (Asteraceae) BJPS
Duarte,Márcia do Rocio; Silva,Ariane Gonçalves.
Gymnanthemum amygdalinum (Delile) Sch.Bip. ex Walp. (Asteraceae), better known by its former name Vernonia amygdalina Delile, is a small shrub used in folk medicine as an antipyretic, laxative, antimalarial and anthelmintic. Studies have demonstrated that different vegetal extracts possess antioxidant, antimicrobial and antiparasitic activities. Among the bioactive metabolites, there are sesquiterpene lactones, saponins, polyphenols and flavonoids. This study investigated the leaf and stem microscopic characters of G. amygdalinum, aiming to expand the knowledge on this medicinal species and indicate anatomical structures. Plant material was fixed and sectioned by freehand and using a microtome. The sections were either stained or underwent standard...

Leaf and stem microscopic identification of Tithonia diversifolia (Hemsl.) A. Gray (Asteraceae) BJPS
Duarte,Márcia do Rocio; Empinotti,Cláudia Bonissoni.
Tithonia diversifolia (Hemsl.) A. Gray is an Asteraceae shrub, popularly known as Mexican sunflower and cultivated for ornamental and therapeutic uses in different countries. In folk medicine, it is of value for treating diabetes, malaria and infectious diseases. These indications have been corroborated by various pharmacological assays. Given the lack of data on anatomical aspects of T. diversifolia, this work aimed to investigate the leaf and stem microscopic characters of this medicinal plant and potential vegetal drug. Samples of mature leaves and young stems were sectioned and stained. Histochemical tests and scanning electron microscopy were also performed. The leaf has anomocytic stomata on both sides, dorsiventral mesophyll and several collateral...

Macro and microscopic characters of the aerial vegetative organs of Carqueja: Baccharis usterii Heering BABT
Budel,Jane Manfron; Duarte,Márcia do Rocio.
This work aimed to study the macro and microscopic characters of the aerial vegetative organs of Baccharis usterii for quality control purposes. The plant was prepared for light and scanning electron microscopic analyses. The stem consisted of three-winged cladodes with small leaves. In the caulinar axis, these was a uniseriate epidermis, chlorenchyma alternating with angular collenchyma, perivascular fibre caps adjoining the phloem which was outside the xylem, and parenchymatic pith. The wings and the leaves were alike, presenting a uniseriate epidermis, palisade parenchyma next to the both sides of the epidermis and spongy parenchyma traversed by minor collateral vascular bundles in the central region. In the leaf midrib, a single collateral vascular...

Morpho-anatomical characters of the leaf and stem of Mandevilla coccinea (Hook. et Arn.) Woodson, Apocynaceae BJPS
Duarte,Márcia do Rocio; Larrosa,Carina Rau Rivas.
Mandevilla coccinea (Hook. et Arn.) Woodson, Apocynaceae is a herb native to South America employed in folk medicine as an analgesic, anti-inflammatory and to inhibit snake venom effects. This work was carried out to study the morpho-anatomical characters of the leaf and stem in order to advance knowledge on this medicinal plant and on pharmacognostic quality control. The plant material was fixed and prepared according to light and scanning electron microtechniques. Its leaves are simple, alternate and ovate-obovate. The epidermis is uniseriate and coated with a thick and striate cuticle. The stomata are paracytic and occur on both foliar surfaces. The dorsiventral-like mesophyll has a sub-epidermal parenchymatic layer containing phenolic substances and is...

Pharmacobotanic characterization of young stems and stem barks of Rauvolfia sellowii Müll. Arg., Apocynaceae BJPS
Baratto,Leopoldo Clemente; Duarte,Márcia do Rocio; Santos,Cid Aimbiré de Moraes.
Rauvolfia sellowii Müll. Arg. (Apocynaceae), a Brazilian native tree rich in indole alkaloids, is known as "pau-pra-tudo" and popularly used as hypocholesterolemic, hypoglycemic and antihypertensive. The aim of this work was to study the anatomy of the young stems and stem barks of this medicinal plant, in order to contribute to the identification of the species as a drug. The plant material was fixed and prepared according to standard microtechniques. The young stems have remaining epidermis, but a suberified peridermis is evident. The phellogen is located in the cortical region, forming suber externally. Underneath the phellogen, lies the phelloderm and collenchymatic region. In the cortex, there are numerous laticifers and some fibers. There is an...
