ABSTRACT
ABSTRACT Dysphania ambrosioides (L.) Mosyakin & Clemants (syn: Chenopodium ambrosoides L.), Amaranthaceae, popularly known as “mastruz”, is an herb widely used in Brazil as anthelmintic. To contribute to the knowledge about medicinal plants, a microscopic analysis was accomplished to describe the main anatomical characters of root, stem, petiole and leaf blade of D. ambrosioides and histochemical tests were performed on the leaf blade. Cross-sections were obtained, by hand, for microscopic analysis of root, stem, petiole and leaf blade; to the leaf blade were still made paradermal sections, scanning electron microscopy analysis, maceration and histochemical tests. The main characters useful in the identification of the plant were: anomalous secondary thickening in the root and stem; presence of idioblasts containing crystal sand in the root, stem, petiole and leaf blade; in these there are also idioblasts with druses; presence of non-glandular and glandular trichomes in the stem, petiole and leaf blade; stomata on the stem, petiole and leaf blade, identified in these as anomocytic and anisocytic; dorsiventral mesophyll and collateral vascular bundles. Maceration revealed that the vessel elements are helical type. Through the histochemical tests, it was evidenced the presence of lipophilic substances, essential oils, oleoresins, phenolic compounds, starch, lignin and calcium oxalate crystals. This work provides support to the quality control of the species.
ABSTRACT
Chenopodium ambrosioides L. é uma erva aromática amplamente distribuída ao longo da América, África e também em países da Europa. No Brasil, a planta é popularmente conhecida como mastruz. Tem sido utilizada pela população como anti-helmíntica e para tratamentos de gripe. O óleo essencial das folhas é o componente mais conhecido da planta e de grande importância científica. As propriedades terapêuticas da planta são geralmente atribuídas ao óleo essencial pelos investigadores. Este trabalho traz uma revisão da literatura sobre o óleo essencial de C. ambrosioides, com ênfase nos seus constituintes químicos, atividade biológica e aspectos toxicológicos.(AU)
Chenopodium ambrosioides L. is an aromatic herb widely distributed throughout the Americas, Africa and also in European countries. In Brazil, the plant is popularly known as mastruz. It has been used by the population as anthelmintic and in the treatment of influenza. The essential oil of the leaves is the most familiar component of the plant and of great scientific importance. The therapeutic properties of the plant are generally attributed to the essential oil. This paper reviews the literature on the essential oil of C. ambrosioides, with emphasis on its chemical constituents, biological activity and toxicological aspects.(AU)

Objetivo: Analisar a ação do extrato de mastruz sobre o crescimento de culturas de Staphylococcus aureus e Escherichia coli. Método:Para avaliar o efeito do extrato de mastruz foram criados os Grupos Stafilococus aureus(Gsa)e o Grupo Escherichia coZi (Gec). O grupo Gsa foi composto de três placas de Petri com cultura de S.aureus, cepa ATC 25923 e em cada uma delas, colocados discos impregnados individualmente com mastruz, gentamicina e oxacilina. No grupo Gec as placas foram semeadas com cepa de E. coli 35218, e também posicionados discos com as três substâncias em estudo. Resultados: Tanto nas culturas de S. aureus como nas de E. coli, não houve halo de inibição induzida pelo extrato de mastruz. Este halo foi observado ao redor dos discos de gentamicina e oxacilina nas culturas de S. aureus e somente nos discos de gentamicina na cultura de E. coli. Conclusão:o extrato de mastruz não tem ação antimicrobiana sobre cepa ATCC 25923 de S. aureus e nem sobre a 35218 de E. coli.
Objective: To analyze the mastruz extract effect on the Staphylococcus aureus and Escherichia coli cultures growth. Method: SaG composed for three Petri plates with S.aureus culture of stump, ATC 25923e in each one of them, put disks impregnated individually with mastruz, gentamicina and oxacilina. EeG stump 35218 composed by three Petri plates with E. coli cultures and in each one of them, paper filter impregnated respectively with mastruz, gentamicina and Oxacilina. Result: ln SaG and in EeG, there was not inhibition induced halo by the mastruz extract. Conclusion:o mastruz extract doesn't have inhibition action on stump ATCC 25923 of S. aureus and to 3521801 E. coli.
