The aim of this study was to assess the activity of aqueous (AE) and ethanolic extracts (EE) and pilocarpine
hydrochloride, which were extracted and isolated from Pilocarpus microphyllus (Jaborandi), respectively, on Rhipicephalus (Boophilus) microplus. High performance liquid chromatography (HPLC) was performed to quantify these compounds. Larval packet and adult immersion tests were conducted with different concentrations. Five AE and EE concentrations, ranging from 6.2 to 100.0 mg mL–1, and six concentrations of pilocarpine hydrochloride, ranging from 0.7 to 24.0 mg mL–1, were tested. The lethal concentration (LC50) of each extract for larvae and engorged females was calculated through Probit analysis. The concentration of pilocarpine hydrochloride obtained from the EE and the AE was 1.3 and 0.3% (m/m), respectively. Pilocarpine hydrochloride presented the highest acaricidal activity on larvae (LC50 2.6 mg mL–1) and engorged females (LC50 11.8 mg mL–1) of R.(B.) microplus, followed by the EE which presented LC50 of 56.4 and 15.9 mg mL–1, for larvae and engorged females, respectively. Such results indicate that pilocarpine hydrochloride has acaricidal activity, and may be the primary compound responsible for this activity by P. microphyllus EE.

O objetivo desse estudo foi avaliar a atividade dos extratos aquoso (AE) e etanólico (EE) e do cloridrato de pilocarpina,
que foram, respectivamente, extraídos e isolado de Pilocarpus microphyllus (Jaborandi), sobre Rhipicephalus (Boophilus)
microplus. Cromatografia líquida de alta eficiência foi realizada para quantificação dos compostos. Testes de pacote de
larvas e de imersão de adultos foram realizados com diferentes concentrações. Cinco concentrações do AE e EE variando
de 6,2 a 100,0 mg mL–1 e seis concentrações do cloridrato de pilocarpina variando de 0,7 a 24,0 mg mL–1 foram testadas.
A concentração letal (CL50) de cada extrato para larvas e fêmeas ingurgitadas foi estimada por meio da análise Probit.
A concentração de cloridrato de pilocarpina obtida do EE e AE foi de 1,3 e 0,3% (m/m), respectivamente. O cloridrato
de pilocarpina apresentou a maior atividade carrapaticida sobre larvas (CL50 2,6 mg mL–1) e fêmeas ingurgitadas
(CL50 11,8 mg mL–1) de R. (B.) microplus, seguido do EE que apresentou CL50 de 56,4 e 15,9 mg mL–1, para larvas
e fêmeas ingurgitadas, respectivamente. Tais resultados indicam que o cloridrato de pilocarpina apresenta atividade
carrapaticida e pode ser o principal responsável pela atividade acaricida do EE de P. microphyllus.

Knowledge of medicinal plants has accumulated over centuries and often represents the only
therapeutic resource of small municipalities in the interior of Brazil. The objective of this study was to
evaluate the knowledge and use of medicinal plants by the population of the municipality of Bom
Princípio do Piauí, Piauí state, for the treatment of diseases in humans and domestic animals.
Interviews were conducted with 38 residents using standardized questionnaire forms, with the
"snowball" technique. Fifty nine families, 98 genera and 112 species were recorded. Of these, 22.3%
were indicated for the treatment of diseases in animals and 9.8% were said to cause adverse effects.
The families with most species were Fabaceae (14), Euphorbiaceae (11) and Lamiaceae (6). The species
with greatest use value (UV) were Myracrodruon urundeuva Allemão (0.65), Dysphania ambrosioides
(L.) Mosyakin and Clemants (0.63) and Amburana cearensis (Allemão) A.C.Sm. (0.42). The leaves were
the parts most frequently used (26.8%), followed by bark (21.0%). Of the 15 used categories listed in this
study, those with the highest number of recorded species were related to illnesses associated with the
digestive tract (102), diseases of the genitourinary system (72) and diseases of the respiratory system
(60). This study revealed the importance of knowledge and use of medicinal plants in caring for the
health of people and domestic animals in the municipality. In addition, the study provided information
on plants of the local flora with pharmacological potential.

The State of Maranhão comprises the second largest coastline in Brazil. Nonetheless, few floristic surveys on restinga
vegetation have been performed in Northeastern Brazil. This study aimed to survey floristic in a restinga of Maranhão, and to assess its similarity to other restingas in the states of Pará and Piauí. Botanical specimens were sampled at Sítio Aguahy, in the municipality of São José de Ribamar, along the eastern coast of Maranhão between June/2012 and October/2013. Species identification and life forms classification followed the usual methods employed in floristic studies. Similarities in plant composition of six sites were estimated based on cluster analysis through Bray-Curtis distance. In the studied area, we found 116 phanerogamic species, 100 genera and 52 families; 19 species were new occurrences for the restinga of Maranhão. Families with largest number of species were Fabaceae, Cyperaceae, Rubiaceae, Poaceae, Myrtaceae, Asteraceae, Malvaceae, Combretaceae, and Eriocaulaceae, which comprised 49.2% of all sampled species. We identified 41 nanophanerophytes, 34 terophytes, 15 camephytes, ten microphanerophytes, six hemicryptophytes, and five lianas. Similarity analyses indicated greater affinity between the restinga flora from the states of Maranhão and Pará than that observed for the states of Maranhão and Piauí, suggesting that the process of species colonization in the former is more likely derived from the Amazon Forest. It is expected that these results may encourage future researchers to conduct further surveys in restinga areas of the Maranhão aiming to better understand the influence of neighboring vegetation on the colonization of the coastal areas of Maranhão.

O Estado do Maranhão possui o segundo maior litoral da costa brasileira. No entanto, poucos levantamentos florísticos foram realizados nas áreas de restinga no Nordeste do Brasil. O presente estudo teve como objetivo realizar um levantamento florístico em uma área de restinga no Maranhão e analisar a similaridade com a flora das restingas dos Estados do Pará e do Piauí. As coletas botânicas foram realizadas na restinga do Sítio Aguahy, município de São José de Ribamar, na porção oriental da Ilha do Maranhão, no período de junho de 2012 a outubro de 2013. A identificação das espécies e a classificação das formas de vida seguiu a metodologia usual em estudos florísticos. A similaridade foi realizada através de análise de cluster a partir da distância de Bray-Curtis, onde foram considerados seis estudos. Foram listadas 116 espécies fanerogâmicas, 100 gêneros e 52 famílias. Deste total, 19 espécies são apresentadas como novas ocorrências para o litoral do Maranhão. As famílias com maior número de espécies foram Fabaceae, Cyperaceae, Rubiaceae, Poaceae, Myrtaceae, Asteraceae, Malvaceae, Combretaceae e Eriocaulaceae, correspondendo a 49.2% das espécies encontradas. Quanto às formas de vida, foram identificados 41 nanofanerófitos, 34 terófitos, 15 caméfitos, 10 microfanerófitos, seis hemicriptófitos e cinco lianas. A análise de similaridade mostrou maior afinidade entre a flora da restinga do Maranhão e do Pará, do que com a flora do Piauí, sugerindo uma possível colonização da restinga estudada por espécies provenientes da floresta Amazônica. Espera-se que esses dados sejam vistos como um passo inicial para a realização de mais pesquisas nas demais restingas maranhenses para que, futuramente, proporcione a compreensão da influência da vegetação circunvizinha na colonização das áreas litorâneas do Maranhão.

O litoral do Piauí apresenta duas formações geológicas distintas: áreas assentadas sobre areias
quartzosas do Quaternário e a Formação Barreiras do Terciário. Este estudo apresenta a composição
florística de tabuleiro litorâneo situado no município de Cajueiro da Praia (PI), além de dados relacionados
aos fatores abióticos para região. Foram comparados os dados sobre a vegetação da região com áreas de
restingas subjacentes. O estudo apresenta uma da lista de 73 espécies, pertencentes a 33 famílias botânicas,
classificadas de acordo com o Sistema APG III.
