“…Solanum paniculatum L. ('Jurubeba') is a medicinal plant whose leaves, fruits and roots are used in traditional medicine against liver problems, besides being used as cholagogue, emmenagogue, healing agent, febrifuge, anti-inflammatory, antipyretic, tonic, decongestant, diuretic and against inappetence (Mesia-Vela et al, 2002;Lorenzi & Matos, 2008;Kaziyama et al, 2012;Grandi, 2014;Garlet et al, 2017).…”

‘Jurubeba’ (Solanum paniculatum L.) is a medicinal plant used in traditional medicine for liver problems, in addition to being used as a cholagogue, emmenagogue, healing agent, febrifuge, anti-inflammatory, antipyretic, tonic, decongestant, diuretic and against inappetence. Thus, the objective of this study was to evaluate the antioxidant activity, concentration of phenolic compounds and total alkaloids of aqueous extracts prepared from ‘Jurubeba’ leaves subjected to drying. ‘Jurubeba’ leaves were dried at different temperatures (40, 50, 60 and 70 °C) and velocities (0.4 and 0.8 m s-1) of the drying air. Aqueous extracts of the leaves, subjected to drying, were evaluated by absorbance reading in a spectrophotometer. Increase in drying air temperature reduced the contents of total phenolics and total alkaloids of the leaf aqueous extracts, whereas increment in air velocity increased the concentration of these substances. Antioxidant activity was not influenced by the increase in air temperature at air velocity of 0.4 m s-1, but under air velocity of 0.8 m s-1 there was reduction with increasing temperature. Drying of ‘Jurubeba’ leaves can be carried out with temperature of 40 or 50 °C and drying air velocity of 0.4 m s-1.

“…Mikania glomerata Sprengel ( M. glomerata , Asteraceae) is a species belonging to the genus Mikania (tribo Eupatorieae, subtribo Miikaniinae) and popularly known as “guaco,” which became official in the first Brazilian Pharmacopoeia because of its therapeutic properties as bronchodilator, antiallergic, and antiasthmatic [ 1 – 3 ]. In addition to the popular use, the M. glomerata presents other therapeutic properties such as antihemorrhagic [ 4 ], antiophidian [ 5 ], antiviral [ 6 ], and antimicrobial [ 7 ].…”

The present study primarily aims to identify the relative density and the fatty acids (methyl esters) content present in the standardized ethanol extract of leaves of M. glomerata (EPMG). Meanwhile, in a second moment, this study evaluated the effects of the EPMG on the levels of amino acids in the hippocampus, and the mechanism of sedative and anxiolytic action. Adult mice were treated with doses of 200, 300, and 400 mg/kg and evaluated in open field, elevated plus-maze, light dark, and rotarod tests. Moreover, in the behavioral tests diazepam (GABAergic anxiolytic, 2 mg/kg) as positive control and flumazenil (GABA antagonist, 2.5 mg/kg) were used to identify mechanism of sedative and anxiolytic action produced by EPMG. The EPMG is constituted by the following compounds: methyl cinnamate, 2H-1-benzopyran-2-one, (2-hydroxyphenyl)methyl propionate, (Z)-methyl-hexadec-7-enoate, methyl hexadecanoate, hexadecanoic acid, (Z)-methyl-octadec-9-enoate, octadecanoic acid, and squalene. This extract demonstrated anxiolytic effects, which may be mediated by GABAergic system, and was able to increase GABA levels and reduce of glutamate and aspartate concentrations in mice hippocampus, which can directly and/or indirectly assist in their anxiolytic effect. Although more studies are needed, the EPMG could represent an interesting therapeutical strategy in the treatment of anxiety.

“…This might explain the resurgence of natural medicine in Brazil in recent years, with emphasis on the use of medicinal plants for health recovery (Yunes et al, 2001;Borba & Macedo, 2006). Plant extracts are not only raw materials for industrial production of pure chemical derivatives, but they are also components of herbal formulations used in the treatment of several diseases (Lima Júnior & Souza, 2005).…”

ABSTRACT:The objective of this study was to critically analyze the scientific production published in specialized Brazilian journals concerning the use of medicinal plants in dentistry. A literature review was carried out using an indirect documentation technique by means of a bibliographical study. Four examiners performed independent searches in Brazilian journals of medicinal plants indexed in the database SciELO (Brazilian Journal of Pharmacognosy; Brazilian Journal of Medicinal Plants; Brazilian Journal of Pharmaceutical Sciences; and Acta Botanica Brasilica) using the descriptors "herbal medicine/phytotherapy" or "medicinal plants" and "dentistry ". The articles published from 2002 to 2012 addressing the use of medicinal plants in dentistry were included and analyzed. The searches based on the descriptors and reading of abstracts, resulted in 155 articles. Of these, 44 were read in full and a total of 16 publications met the eligibility criteria and were selected. Laboratory studies predominated (10) and were limited to the evaluation of antimicrobial properties by means of tests for determining inhibitory, fungicidal and bactericidal concentrations. Three literature reviews and only one clinical trial with no blinding and randomization were found. It is highlighted the need for better methodological designs in the researches and greater production of clinical or in vivo studies.Key words: Dentistry, Ethnobotany, Medicinal Plants, Phytotherapy, Plant Extracts. RESUMO: Produção científica brasileira sobre o uso de plantas medicinais na odontologia.O objetivo deste estudo foi analisar criticamente a produção científica acerca do uso de plantas medicinais em Odontologia nos periódicos brasileiros especializados. Realizou-se uma revisão da literatura, utilizando técnica de documentação indireta a partir de um estudo bibliográfico. Quatro pesquisadores procederam, de forma independente, uma busca nas revistas brasileiras de plantas medicinais indexadas na base de dados Scielo (Revista brasileira de farmacognosia; Revista brasileira de plantas medicinais; Brazilian journal of pharmaceutical sciences; Acta botânica. brasílica) utilizando como descritores "fitoterapia" ou "plantas medicinais" e "Odontologia". Os artigos publicados de 2002 a 2012 que envolveram o uso de plantas medicinais em Odontologia foram incluídos e analisados. A busca por descritores e leitura de resumos gerou 155 artigos, dos quais 44 foram lidos na íntegra, sendo selecionadas 16 publicações que se enquadraram aos critérios requeridos. Estudos laboratoriais foram majoritários (10), e limitaram-se em avaliar propriedades antimicrobianas através das concentrações inibitórias, fungicidas e bactericidas. Três foram revisões da literatura e apenas um ensaio clínico esteve presente, sendo o cegamento e a randomização ausentes. Evidenciou-se a necessidade de um melhor delineamento metodológico das pesquisas e de uma maior produção de estudos clínicos ou in vivo.Palavras-chave: extratos vegetais, etnobotânica, fitoterapia, odontologia, plantas medic...
