Combretum leprosum Mart. (Combretaceae), a shrub popularly known as mofumbo, is used in folk medicine for treatment of uterine bleeding, pertussis, gastric pain, and sedative. The aim this study was to (1) determine the phytochemical profile,(2) identify chemical constituents (3) examine antioxidant cytogenotoxic activity ethanolic extracts fractions stem bark leaves. plant material (leaf bark) submitted extraction with ethanol, followed by partition using hexane, chloroform, ethyl acetate....
The acute toxicity, the antioxidant activity, and pharmacological activity on gastrointestinal tract of rodents ethanolic extract (TFEE) from bark Terminalia fagifolia Mart. & Zucc. (Combretaceae) its aqueous (TFAqF), hydroalcoholic (TFHAF), hexanic (TFHEXF) partition fractions have been evaluated. TFEE presented low antioxidant, antiulcerogenic against ethanol-induced ulcers, which was partially blocked by pretreatment with L-NAME indomethacin. It reduced total acidity raised pH gastric...
A fração em acetato de etila (EtOAc) obtida a partir da partição do extrato etanol (EtOH) das folhas O. sessiliflora R. E. Fries (Annonaceae) foi submetida diversos procedimentos cromatográficos, incluindo cromatografia líquida alta eficiência (HPLC), o que resultou no isolamento dos flavonóides: quercetina 4).As estruturas foram definidas através análise espectros ressonância magnética nuclear (NMR) 1 H e 13 C (1D 2D) espectrometria massas.The ethyl acetate phase obtained from the partition...
For the first time, chemical composition and cytotoxic evaluation of essential oils from leaves of Oxandra sessiliflora R. E. Fries (Annonaceae) has been reported. Leaves of O. sessiflora were collected in four different periods during years 2010 (September December) 2011 (March June). The oils, obtained by hydrodistillation procedures, were analyzed Gas chromatography (GC) chromatography-Mass spectrometry (GC-MS). Chemically, predominance hydrocarbon sesquiterpenes was detected (57.54 to...
A Tocoyena hipidula Standl. (Rubiaceae), conhecida como flor-do- cerrado no Brasil, é utilizada popularmente tratamento de dores abdominais e inflamações útero etc. O extrato etanólico das folhas (Th-EtOHf) em estudos anteriores mostrou baixa citotoxicidade MTT atividade antidiarreica sobre protocolos diarreia aguda. Objetivo: Investigar a espasmolítica do Th-EtOHf íleo isolados rato.
Gardenieae is a tribe belonging the Rubiaceae family, subfamily Ixoroideae, considered most extensive, with about 100 genera, constituting complex and morphologically diverse group.Considering iridoids are chemotaxonomic markers of this work shows diversity these metabolites bioativities reported for species tribe.A total 115 3 noriridoids, distributed in 10 genera 24 were reported, gardenoside (4) being frequent iridoid, Gardenia jasminoides highest number compounds.A range biological...
Samanea tubulosa Benth. it has been widely used in traditional medicine to treat inflammatory processes. The present study aimed investigate the antinociceptive effect and mechanism of action fractions obtained from pods mice. activity was evaluated formalin, capsaicin glutamate tests the. possible mechanisms involved hexane ethyl acetate fraction opioid system, also K + ATP channels L-arigine pathways nitric oxide were evaluated. chemical characterization analysis revealed presence...
