“…Os teores de óleo essencial obtidos para a camomila no presente estudo estão coerentes com a literatura (COSTA, 2001;GUENTHER, 1952;POVH et al, 2001;SALAMÓN, 1992), porém aquém do seu potencial de até 1,8% (BORSATO, 2006;DONI-FILHO;AHRENS, 2005a;2005b). Provavelmente, o rendimento de óleo essencial extraído por meio do modelo de destilador utilizado poderia ter sido maior ou pelo menos equivalente ao obtido pela hidrodestilação (testemunha).…”

“…Em relação à composição química do óleo essencial da camomila foram identificados 12 componentes em todas as amostras analisadas, que embora apresentem diferentes concentrações (Tabelas 1 e 2), estão coerentes com a literatura (BORSATO, 2006;DONALÍSIO, 1985;GUENTHER, 1952;MATOS et al, 1993;POVH et al, 2001;RAAL et al, 2003;SALAMÓN, 1992). A seqüência de eluição dos componentes do óleo essencial da camomila também pode ser visualizada no perfil cromatográfico (Figura 1), que representa todas as amostras analisadas, uma vez que seus cromatogramas diferem apenas em concentração dos componentes.…”

129Rendimento e composição química do óleo essencial da camomila [Chamomilla recutita (L.) ResumoCom o objetivo de avaliar o rendimento e a composição química do óleo essencial de camomila submetida a um sistema de extração por arraste de vapor, em escala comercial, monitorou-se periodicamente o processo realizado, no município de Campo Largo -PR, num modelo utilizado pela "CHAMEL Ind. e Com. de Produtos Naturais Ltda.", na safra de 2005. As determinações analíticas foram realizadas em laboratórios da UFPR, por meio da hidrodestilação e cromatografia gasosa acoplada à espectrometria de massas. Os dados obtidos indicam que o óleo essencial da camomila extraído por meio do modelo de destilador utilizado apresentou qualidade aquém das expectativas. Grande parte do óleo essencial, inclusive seus principais componentes, estava sendo perdida junto ao hidrolato. No processo de destilação o monitoramento periódico de indicadores de qualidade e de eficiência é imprescindível para estabelecer condições adequadas de operacionalização. Palavras-chave: Alfa-bisabolol, camazuleno, CG-EM AbstractThe distillation process was periodically monitored, on Campo Largo-PR, in "CHAMEL Ind. e Com. de Produtos Naturais LTDA.", in the 2005 harvest. The hydrodistillation and GC-MS analyses were done in the UFPR Laboratories. The obtained data indicate that the chamomile essential oil extracted through the distiller model used presented low quality. Great part of the essential oil, besides their main components, it was being lost with the hidrolato. In the distillation process the periodic evaluation of quality and efficiency indicators is indispensable to establish appropriate operational conditions.

“…Although this region presents similar climatic characteristics, differences in EO chemical composition were observed. This variability in EO chemical composition may be associated with the influence of environmental factors such as temperature and humidity, edaphic factors, and genetic variability (Borsato et al 2007, Gobbo-Neto & Lopes 2007, Cerqueira et al 2009. The EO analyzed in this study was obtained from a single species, in the same locality, and under the same conditions.…”

Biocidal potential of Eugenia pyriformis essential oil in the control of Rhipicephalus (Boophilus) microplus in the free-living cycle

et al. 2019

Brazil has one of the largest commercial cattle herds in the world, which naturally coexist with an enormous number of parasitic species. Southern cattle tick, Rhipicephalus (Boophilus) microplus, is among these species, interfering with animal productivity and causing losses to the beef and dairy cattle sector. The use of chemical acaricides in the control of this mite has resulted in the emergence of resistant populations. In this sense, alternative control measures using plants as sources of botanical acaricides have shown to be effective. Eugenia pyriformis Cambess is a Brazilian plant with antioxidant and antimicrobial activity; however, there are no reports on its acaricidal activity in the literature. The present study aimed to evaluate the acaricidal and larvicidal potential of E. pyriformis leaf essential oil (EO) on southern cattle tick at different stages of the reproductive cycle. E. pyriformis leaves were collected and dried, and had their EO extracted by hydrodistillation (3h) using a modified Clevenger apparatus. Chemical analysis was performed by gas chromatography coupled with mass spectrometry (GC/MS), and 32 compounds belonging to the sesquiterpene class were identified: hydrocarbons (17.98%) and oxygenated forms (81.96%), with spathulenol (43.65%) and caryophyllene oxide (12.17%) as the most common. The EO was evaluated by the Adult Immersion Test at the concentrations (500.00 to 3.12mg/mL) in which the following parameters were measured: mortality of females (%), hatchability of eggs (%), and product efficiency (%). Larvae were assessed by the Larval Packet Test at concentrations ranging from 25.00 to 0.00004mg/mL. Lethal concentrations (LC) required for killing 50 and 99.9% of adult females and larvae were determined using Probit analysis. LC50 and LC99.9 of EO were 0.06 and 24.60mg/mL and 1,208.80 and 2,538mg/mL for larvae and adult females, respectively. Action of the EO in the free-living cycle of R. (B.) microplus larvae was another parameter assessed. To this end, the larvae were deposited in pots containing Brachiaria decumbens and, after migration to the leaf apex, a solution containing LC99.9 (24.60mg/mL) of the EO was sprayed. After 24h, 72.25% of the larvae had died, indicating stability of the EO when subjected to uncontrolled temperature and humidity conditions. The mechanism of action through which the EO killed the larvae and adult females was investigated by the Bioautographic Method, which showed inhibition of 3.15mg/mL of the EO on the acetylcholinesterase (AChE) enzyme. The results found in the present experiment indicate that E. pyriformis essential oil is an alternative in the control of southern cattle tick in the larval (parasitic) and free-living cycle (non-parasitic) stages under field conditions.

Medicinal plants for the "nerves": a review of ethnobotanical studies carried out in South Brazil

et al. 2019

Among the medicinal purposes for which plants have been used is the treatment of "nerves". Th e objective of this study was to search for species of plants used in the state of Rio Grande do Sul (South Brazil) for the relief of symptoms related to central nervous system (CNS) disorders. Twenty-seven ethnobotanical studies were compiled, in which a total of 94 species were cited. Th e fi ve most cited species were Cymbopogon citratus (81.5 %), Melissa offi cinalis (77.7 %), Aloysia citriodora (66.6 %), Matricaria chamomilla (62.9 %) and Passifl ora edulis (51.8 %). Scientifi c studies have corroborated the popular use of these plants as sedatives, but most studies are preclinical and very few have been clinical (M. chamomilla and M. offi cinalis), and these were mainly exploratory or were performed against placebo. In addition to effi cacy data, there are also indications of toxicity for M. chamomilla and P. edulis. In conclusion, there is a great diversity of plant species used in the treatment of symptoms related to CNS disorders, and they are most frequently used as a sedative. Data indicate that M. offi cinalis possesses clinical effi cacy in the treatment of symptoms associated with anxiety without signs of toxicity.
