RESUMO: O uso de plantas medicinais no tratamento de doenças é uma estratégia antiga utilizada por praticamente todas as populações do mundo, e, embora novos antibióticos tenham sido desenvolvidos para o controle de micro-organismos infecciosos, às vezes são ineficazes. Diversos extratos de plantas medicinais têm efeitos antimicrobianos, principalmente quando associados à antibióticos de uso clínico, representando alternativa terapêutica para doenças infecciosas. Montrichardia linifera, conhecida popularmente como aninga, é espécie macrófita, aquática emergente de hábito herbáceo, pertencente a família Araceae e ocorre em áreas alagáveis. A utilidade farmacológica desta espécie é diversificada tendo sido relatada como cicatrizante, antirreumático, antidiurético e expectorante. Devido à relevância no campo etnofarmacológico, ampla utilização na medicina popular e escassez de trabalhos relacionados à atividade antibacteriana desta espécie, objetivou-se com este trabalho avaliar a atividade antibacteriana de extratos alcoólicos de folhas de Montrichardia linifera, coletadas na margem do rio Igaraçu, Parnaíba-PI. O extrato foi testado em oito cepas de bactérias: Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis, Escherichia coli, Klebsiella pneumoniae e Pseudomonas aeruginosa. Foram utilizadas as técnicas de verificação da formação de halos de inibição e determinação das concentrações inibitórias e bactericidas mínimas. Os testes antibacterianos evidenciaram como principais resultados que o extrato metanólico seco (EMS), extrato metanólico fresco (EMF), e o extrato etanólico seco (EES), apresentaram ação antibacteriana, enquanto o extrato etanólico fresco (EEF) não apresentou atividade para as bactérias testadas. O EMS foi o mais eficiente, inibindo o crescimento bacteriano na concentração de 200 μg/mL para E. faecalis, 400 μg/mL para S. aureus, 400 μg/mL para S. epidermidis e 2.000 μg/mL para P. aeruginosa. O EMF obteve CIM de 2.000 μg/mL para E. faecalis e EES obteve CIM de 250 μg/mL para E. faecalis. Os resultados demonstraram que M. linifera constitui fonte eficiente de compostos bioativos antibacterianos. Os estudos sobre as propriedades farmacológicas de plantas da família Araceae são escassos, e os resultados deste trabalho são pioneiros em relação a atividade antibacteriana desta espécie.

ABSTRACT: Antibacterial activity of leaf extracts of Montrichardia linifera (Arruda) Schott (Araceae). For a long time, medicinal herbs have been used in the treatment of diseases by almost all populations in the world, and although new antibiotics have been developed for the control of infectious micro-organisms, they are sometimes ineffective. Many herbal extracts have antimicrobial effects and represent a potential alternative therapy for infectious diseases, especially when associated with the clinical use of antibiotics. The Montrichardia linifera, popularly known as Aninga, is a robust, herbaceous, emergent aquatic macrophyte belonging to the Araceae family, appearing along rivers and stream margins in the tropical America. The pharmacological application of this species are several ones, having been reported to own a healing, antirheumatic, anti-diuretic and expectorant effect. Due to the relevance in the ethnopharmacological field, the spread use in popular medicine and the few researches related to the antibacterial activity of this specie, the study aimed to evaluate the antibacterial activity of alcoholic leaf extracts of plants of Montrichardia linifera collected along the margins of Rio Igaraçu, Parnaíba, Piauí, Brazil. The extract was tested in eight strains of ATCC bacterial standards: Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis, Escherichia coli, Klebsiella pneumonia and Pseudomonas aeruginosa. The verification techniques used were the formation of inhibition halos, and the determination of minimum inhibitory and bactericidal concentrations (MIC). The antibacterial tests showed, as main results, that dried methanol extract (EMS), fresh methanol extract (EMF) and dry ethanol extract (EES) exhibited antibacterial activity, while the fresh ethanol extract (EEF) was inactive against the tested bacteria. The EMS was the most efficient one, inhibiting bacterial growth at a concentration of 200 μg/mL for E. faecalis, 400 μg/mL for S. aureus 400 μg/mL for S. epidermidis and 2.000 μg/mL for P. aeruginosa. The EMF obtained a MIC of 2.000 μg/mL for E. faecalis and EES obtained a MIC of 250 μg/mL for E. faecalis. The results showed that M. linifera is an efficient source of bioactive antibacterial compounds. Studies about the pharmacological properties of plants of the family Araceae are scarce, and the results of this work are pioneer in regard to the antibacterial activity of this species.

Keywords: Araceae, bioactivity, alcoholic extracts, antibacterial activity.

An ethnobotanical survey of medicinal plants used by the Sobradinho community, Luís Correia, Piauí, Brazil was undertaken to recover and document traditional knowledge with the aim of supporting chemical, biological, agronomic, pharmaceutical and socio-economic studies related to the region's biodiversity. Fifteen research visits to the community were made between March 2013 to January 2014 involving 31 respondents from the community, the majority (74.4%) being women aged between 27 and 84 years. The methodology used was interview by the snowball method using questionnaires. Analysis of the data gathered was based on use value and the Shannon-Wiener diversity index. Botanical voucher specimens were made of the species cited by informants and deposited at the HDELTA herbarium. 57 species belonging to 33 families were identified, of which 56% were native and 44% exotic. The best represented families were Fabaceae (14%), Lamiaceae and Myrtaceae (9% each). The leaves were the most frequently used plant parts (69%), followed by the stem (22%), fruit (4%), flower (2%), root and seed (1%). The species that showed the highest use value (VU) were Cymbopogon
citratus (DC.) Stapf (capim-santo) and Morinda citrifolia L. (noni) with VU = 0.26. The Shannon-Wiener index value was highest for the elderly group (n=15, 48% of total respondents), but young people were not represented among the informants. A total of 67 different medicinal indications were recorded, the highest number of species being used to treat medical conditions associated with inflammation, pain and fever. Informants claimed to have learned the use of medicinal plants from older members of the community and there was little interest evident among young people in acquiring this knowledge. Community informants are the holders of medicinal plant knowledge of the local flora and its practical application.

(Anacardiaceae) from the coastal region of Piauí, Brazil0 aGeometric morphometrics of leaves of Anacardium microcarpum Duck c07/2014 a315-3270 v373 a

Anacardium microcarpum (cajuí) differs from A. occidentale (cashew) by its smaller drupe and hypocarp and more restricted range in cerrados and coastal plateaux of Brazil’s Pará, Maranhão, Piauí, Ceará and Rio Grande do Norte states. Taxonomists treat A. microcarpum as conspecific with A. occidentale, but many agronomists treat it as distinct. This study used geometric morphometrics to investigate leaf shape differences between the two taxa in ten populations from coastal Piauí state, Brazil with samples of 300–380 leaves. Configurations of two landmarks and 14 semilandmarks were digitized along the leaf outline from standardized images and subjected to multivariate analysis after Procrustes alignment. Principal component analysis produced four significant principal component shape variables accounting for 79.5 % total variance. These were visualized using thin-plate spline analysis. Discriminant analysis showed a significant difference between the taxon means (P = 0.003). Jackknife cross-validation correctly classified only 61.3 % of A. occidentale individuals and 56.7 % of A. microcarpum. Non-Parametric MANOVA of the ten populations showed significant population differences (P = 0.0001). The most isolated population (Cocal da Estação)—the only one from the interior of the state—differed most. A Mantel test found no significant correlation between morphological dissimilarity and geographical distance. Although leaf shape differences both between taxa and populations were statistically significant, overlap made leaf shape difference alone ineffective for separating A. microcarpum from A. occidentale.

The study consists of a taxonomic treatment of the Araceae of Ceará, a state lying within Brazil’s semi-arid region. The aroid flora shows greater similarity to those of central Brazil and Amazonia than to the Atlantic forest. Most species occur in humid forest fragments - the “florestas serranas”. Geophytes are also found in caatinga and dry forest (Taccarum ulei) and lithophytes on rock outcrops in dry forest (Philodendron acutatum). Floating aquatics occur in ponds and lakes throughout the state (Pistia stratiotes, Lemna aequinoctialis, Lemna minuta, Spirodela intermedia, Wolffia columbiana, Wolffiella welwitschii), and freshwater helophytes (Montrichardia linifera) along river margins. 28 taxa (species and varieties) in 19 genera are described and most are illustrated: Anthurium (three spp.), Caladium (one sp.), Dieffenbachia (one sp.), Dracontium (one sp.), Lemna (two spp.), Monstera (two spp., one with two varieties), Montrichardia (one sp.), Philodendron (four spp.), Pistia (one sp.), Scaphispatha (one sp.), Spathicarpa (one sp.), Spathiphyllum (one sp.), Spirodela (one sp.), Syngonium (one sp.), Taccarum (one sp.), Wolffia (one sp.), Wolffiella (one sp.), Xanthosoma (two spp.), Zomicarpa (one sp.). New records for Ceará are Dieffenbachia aglaonematifolia, Dracontium nivosum, Monstera adansonii var. laniata, Philodendron sp. aff. ruthianum and the naturalized exotic Typhonium roxburghii. An identification key and data on geographic distribution and conservation status are provided.

Genetic variation was investigated using AFLP markers in 12 populations of Anthurium sinuatum and A. pentaphyllum var. pentaphyllum (Araceae) in north-east Brazil, Amazonia and the Brazilian Atlantic forest. Two unique genetic patterns characterized the populations of A. sinuatum as a group, but no correlation between genetic and geographical interpopulation distance was found; the Amazonian population was not separated from that in Ceará. The isolated Ceará brejo populations of A. sinuatum were genetically distinct, but genetic diversity levels were similar to populations elsewhere, with no evidence of genetic erosion. Anthurium pentaphyllum populations were significantly different from each other; Bayesian genetic structural analysis found no common genetic pattern, but revealed genetic clusters unique to subgroups and individual populations in the Atlantic forest and French Guiana. Anthurium pentaphyllum and A. sinuatum can be distinguished genetically, but individuals of both species formed intermediate genetic clusters that blurred their distinction. We suggest that genetic mixing of A. sinuatum and A. pentaphyllum has occurred in north-east Brazil, possibly connected with cycles of humid forest expansion. The weak genetic structure in A. sinuatum is consistent with the natural fragmentation of continuous forest areas, possibly during the Holocene.

† Background and Aims This study sought genetic evidence of long-term isolation in populations of Monstera adansonii var. klotzschiana (Araceae), a herbaceous, probably outbreeding, humid forest hemi-epiphyte, in the brejo forests of Ceara´ (north-east Brazil), and clarification of their relationships with populations in Amazonia and the Atlantic forest of Brazil. † Methods Within-population genetic diversity and between-population dissimilarity were estimated using AFLP molecular markers in 75 individuals from eight populations located in Ceara´, the Brazilian Atlantic Forest and Amazonia. † Key Results The populations showed a clinal pattern of weak genetic differentiation over a large geographical region (FST ¼ 0.1896). A strong correlation between genetic and geographical distance (Mantel test: r ¼ 0.6903, P ¼ 0.002) suggests a historical pattern of isolation by distance. Genetic structure analysis revealed at least two distinct gene pools in the data. The two isolated Ceara´ populations are significantly different from each other ( pairwise FPT ¼ 0.137, P ¼ 0.003) and as diverse (Nei’s gene diversity, average He ¼ 0.1832, 0.1706) as those in the Atlantic and Amazon forest regions. The population in southern Brazil is less diverse (Nei’s gene diversity, average He ¼ 0.127) than the rest. The Ceara´ populations are related to those of the Atlantic forest rather than those from Amazonia (AMOVA, among-groups variation ¼ 11.95 %, P ¼ 0.037). †Conclusions The gene pools detected within an overall pattern of clinal variation suggest distinct episodes of gene flow, possibly correlated with past humid forest expansions. The Ceara´ populations show no evidence of erosion of genetic diversity, although this was expected because of their isolation. Their genetic differentiation and relatively high diversity reinforce the importance of conserving the endangered brejo forests..

Leaf characters of populations of the aquatic macrophyte Montrichardia linifera were studied using geometric morphometrics to compare variation with traditional circumscriptions of the two recognized species. Two hundred and ten individuals were sampled from seven populations in the delta region of the Rio Parnaíba, north-east Brazil. Six landmarks of the leaf blade were digitized from images and analysed with MorphoJ software. Procrustesaligned configurations were studied using principal component analysis and canonical variates analysis in the pooled data and individual populations. Sinus shape variation was studied using landmark configurations of the posterior lobe basiscopic lamina. Covariation of leaf blade shape, basiscopic lamina shape, secondary vein number and petiole ligule length was investigated with partial least squares analysis. Allometry of these variables with leaf blade centroid size was investigated using multivariate regression, linear modelling and analysis of covariance. Measured variables varied continuously over the ranges previously reported for the two species. The characters of the two species morphotypes covaried and were only partly influenced by allometric effects. Symmetric shape variables predominated, but a distinctive left- and right-handed asymmetry occurred in all populations. Genetic and ecological studies are needed to investigate the significant inter-population differences further. The study offers a methodology for a broader combined morphometric/molecular investigation
