Bioprospecting the Cerrado’s Aromatic Flora: Chemical and Biological Studies of...
Rodrigues,Gardênia Barbosa Carrijo; Fernandes,Cassia Cristina; Marcionilio,Suzana Maria Loures de Oliveira; Martins,Carlos Henrique GomesAbstract Chemical and pharmacological potentials of botanical species found in the Cerrado are well-known and widely studied. Chemical diversity of secondary metabolites produced by plants that belong to this Brazilian biome has triggered several studies in the fields of farming, pharmaceutical and cosmetic industries. Therefore, this study aimed at evaluating the chemical composition of essential oils (EOs) fr...
First report on chemical composition and biological properties of volatile oil ...
Fernandes,Cassia Cristina; Chrystal,Pietro; Pereira,Alexandra Cristine; Colli,Ana Carla; Stenico,Livia; Ribeiro,Arthur Barcelos; Squarisi,Iara SilvaBrazil has the greatest plant diversity in the world. Many species exhibit a wide range of phytochemical compounds which can be exploited in food, agronomic, pharmacological and medicinal plant industries. Therefore, the chemical composition and in vitro bioactivities of volatile oil from Psidium firmum fresh leaves (PfVO) were investigated for the first time. GC-FID and GC-MS analyses revealed 28 compounds in ...
Bioactivities of essential oils from different parts of Spiranthera odoratissim...
Cabral,Fernando Duarte; Fernandes,Cassia Cristina; Ribeiro,Arthur Barcelos; Squarisi,Iara Squarisi; Tavares,Denise CrispimAbstract This paper aims to investigate, for the first time, in vitro antitubercular, antileishmanial and antiproliferative activities of essential oils (EOs) from S. odoratissima leaves and flowers - grown in midwestern Brazil - against Mycobacterium tuberculosis, promastigote forms of Leishmania amazonensis and human tumor cell lines. Antimycobacterial activity of EOs was evaluated in terms of the minimal inh...
Essential Oil from Psidium cattleianum Sabine (Myrtaceae) Fresh Leaves: Chemica...
Chrystal,Pietro; Pereira,Alexandra Cristine; Fernandes,Cassia Cristina; Souza,João Matias de; Martins,Carlos Henrique Gomes; Potenza,JúliaAbstract Endodontic infections result from oral pathogenic bacteria which reach and infect dental pulp, as well as surrounding tissues, through cracks, unrepaired caries and failed caries restorations. This study aims to determine the chemical composition of essential oil from Psidium cattleianum leaves (PC-EO) and to assess its antibacterial activity against endodontic bacteria. Antibacterial activity of PC-EO...
Brazilian Green Propolis: Chemical Composition of Essential Oil and Their In Vi...
Quintino,Ricardo Lanzellotti; Reis,Ana Carolina; Fernandes,Cassia Cristina; Martins,Carlos Henrique Gomes; Colli,Ana CarlaAbstract Propolis is a resinous substance collected and processed by Apis mellifera from parts of plants, buds and exudates. In Minas Gerais (MG) state, Brazil, green propolis is produced from the collection of resinous substance found in shoot apices of Baccharis dracunculifolia. This paper aims to investigate the chemical composition and in vitro antioxidant, anti-Helicobacter pylori, antimycobacterial and an...
Direito à cidade, direito à saúde: quais interconexões?
Figueiredo,Glória Lúcia Alves; Martins,Carlos Henrique Gomes; Damasceno,Jaqueline Lopes; Castro,Gisélia Gonçalves de; Mainegra,Amado BatistaResumo O direito à saude se interconecta com o direito à cidade na medida em que, ao se garantir espaços urbanos saudáveis para a população, garante-se também a redução de iniquidades e a expansão do usufruto dos efeitos positivos da urbanização a grupos postergados e desfavorecidos. A interconexão entre o direito à cidade e o direito à saúde é hipotetizado como propulsor necessário à promoção da equidade. Este...
Photovoice como modo de escuta: subsídios para a promoção da equidade
Touso,Maíra Ferro de Sousa; Mainegra,Amado Batista; Martins,Carlos Henrique Gomes; Figueiredo,Glória Lúcia AlvesResumo A partir de observações no campo da Promoção da Saúde, junto a pacientes de um Centro de Reabilitação no interior de São Paulo, notou-se que eles apresentam dificuldades em lidar com as limitações físicas adquiridas quando estas os incapacitavam para o trabalho. Objetivou-se ampliar os modos de escuta para facilitar o diálogo com pessoas em situações de debilidade física e afastadas de suas atividades la...
Endodontics pastes formulated with copaiba oil: action on oral microbiota and d...
Dias,Fernanda Gosuen Gonçalves; Casemiro,Luciana Assirati; Martins,Carlos Henrique Gomes; Dias,Luis Gustavo Gosuen Gonçalves; Pereira,Lucas de FreitasThis study analysed the effect of pastes formulated with calcium hydroxide P.A. and different vehicles (saline solution - paste A and Copaifera langsdorffii Desfon oil - paste B) on oral microorganisms and dentin bridge formation in dogs. The antimicrobial action of the pastes and their components was analysed by the minimum inhibitory concentration in agar gel technique. The components were diluted and tested ...
Antimicrobial activity of the essential oil of Tetradenia riparia (Hochst.) Cod...
Melo,Nathalya Isabel de; Carvalho,Carlos Eduardo de; Fracarolli,Letícia; Cunha,Wilson Roberto; Veneziani,Rodrigo Cassio SolaIn Brazilian folk medicine, Tetradenia riparia (Hochst.) Codd. (Lamiaceae) is used to treat toothaches and dental abscesses and diseases induced by worms, bacteria, or fungi. This paper aims to investigate the chemical composition and the antibacterial effects of the essential oil obtained from Tetradenia riparia leaves (TR-EO) grown in Southeastern Brazil against a representative panel of oral pathogens. We ev...
CHEMICAL STUDY OF Hortia superba (Rutaceae) AND INVESTIGATION OF THE ANTIMYCOBA...
Severino,Vanessa Gisele Pasqualotto; Felix,Monteiro Afif; Silva,Maria Fátima das Graças Fernandes da; Lucarini,Rodrigo; Martins,Carlos Henrique GomesIn this paper, the chemical study of Hortia superba and antimycobacterial potential of Hortia species were investigated. Crude extracts and limonoids, alkaloids, dihydrocinnamic acid derivatives and coumarins isolated from Hortia superba, Hortia oreadica and Hortia brasiliana were evaluated against Mycobacterium tuberculosis H37Rv, Mycobacterium kansasii and Mycobacterium avium. The results obtained demonstrate...
