“…Symbols indicate inhibitory concentrations as follows: : control (no drug); : 0.39 µg/ml (0.25 x MIC); : 0.78 µg/ml (0.5 x MIC); λ: 1.56 µg/ml (1 x MIC); : 3.12 µg/ml (2 x MIC); : 6.25 µg/ml (4 x MIC); ς: 12.5 µg/ml (8 x MIC) µg/ml to Epidermophyton floccosum, and 1000 µg/ml to Trichophyton rubrum. Lentz et al (1998) had screened Honduran medicinal plant species for antimicrobial activity. The extract from P. aduncum showed inhibition zones measuring 7 mm against both S. aureus and B. subtilis, and measuring 22 mm against Mycobacterium intracellulare.…”

“…Of additional value is the standard screening of plants for the presence of bioactive compounds, and the assessment of extract toxicity via bioassays. Toxicity assays have been performed on plant extracts from the ethnomedicinal flora of several countries, including Argentina (Mongelli et al, 1996), Brazil (Quignard et al, 2004), Guatemala (Franssen et al, 1997;Cáceres et al, 1998;Michel et al, 2007), Honduras (Lentz et al, 1998), India (Padmaja et al, 2002), Jamaica (Facey et al, 1999), New Guinea (Rao, 1996), Philippine Islands (Horgen et al, 2001), Spain (Serrano, 1996), Tanzania (Moshi et al, 2004), and Turkey (Sener et al, 1998). A massive new and important project recently announced is the Herbalome Project by the Chinese government to assay for chemical constituents and toxicity the 400,000 medicinal preparations derived from 10,000 medicinal species used in Chinese traditional medicine (Stone, 2008).…”

RESUMO:O gênero Mikania, pertencente à família Asteraceae e à tribo Eupatoriae, tem cerca de 430 espécies distribuída principalmente na América do Sul. No Brasil, o gênero está representado por aproximadamente 171 espécies. Várias espécies do gênero Mikania de hábito trepador recebem a denominação vulgar de "guaco". Mikania laevigata Sch. Bip. ex Baker, conhecida como "guaco", "guaco-de-casa" e "guaco-do-mato", é uma espécie nativa do sul do Brasil. Suas folhas são empregadas na medicina tradicional como expectorante e como anti-reumáticas. É muito semelhante morfologicamente com M. glomerata, que é a espécie oficializada pela Farmacopéia Brasileira I. Alguns estudos de M. laevigata comprovaram atividades farmacológicas como, antiinflamatória, antimutagênica, antimicrobiana e antiulcerogênica. Objetivou-se estudar a morfologia externa e a anatomia do caule e da folha de M. laevigata, com a finalidade de fornecer dados farmacognósticos referentes à identificação e à diferenciação dessa espécie das demais Mikania, visando o controle de qualidade da matéria-prima. O material botânico foi submetido às microtécnicas fotônicas e eletrônicas de varredura usuais. As características morfoanatômicas descritas para a folha e o caule de M. laevigata auxiliam na identificação da espécie.Unitermos: Asteraceae, Mikania laevigata, controle de qualidade.ABSTRACT: "Contribution to the pharmacognostic study of Mikania laevigata Sch. Bip. ex Baker "Guaco" for the quality control". The genus Mikania, belonging to the family Asteraceae and tribe Eupatoriae, has about 430 species mainly distributed in South America. In Brazil, the genus is represented by approximately 171 species. Various members of Mikania are lianas and commonly called "guaco". Mikania laevigata Sch. Bip. ex Baker, known as "guaco", "guaco-decasa" and "guaco-do-mato", is native to the South of Brazil. Its leaves are used in folk medicine as expectorant and antirheumatic. It is morphologically similar to M. glomerata, whose monograph is included in the Brazilian Pharmacopoeia 1st Ed. Some studies on M. laevigata have demonstrated pharmacological activities, such as anti-inflammatory, antimutagenic, antimicrobial and antiulcerogenic. This work has aimed to study the morpho-anatomy of the stem and the leaf of M. laevigata, in order to supply pharmacognostic information related to the identification of this species and distinction from other Mikania for quality control purposes. The botanical material was prepared according to standard light and scanning electronic micro techniques. The morphoanatomical characters described for the stem and the leaf contribute to the identification of this species.
