Autores: Isquierdo,Eder P.; Caldeira,Daniela S. A.; Siqueira,Valdiney C.; Martins,Elton A. S.; Quequeto,Wellytton D.
ABSTRACT This study aimed to obtain and evaluate thermodynamic properties and hygroscopic equilibrium isotherms of urunday seeds as a function of air relative humidity and temperature, as well as identify the best-fitted mathematical models for adsorption phenomenon. A static-gravimetric method was used to obtain hygroscopic equilibrium moisture content. Seeds were placed in airtight containers with different saturated saline solutions for relative humidity control. These were then kept in BOD incubator chambers at 10, 20, 30, and 40 °C. Hygroscopic equilibrium moisture content decreased as temperature increased, for the same water activity. The Sigma-Copace model best-fitted seed adsorption data for equilibrium water activity intervals between 0.1129 and...

Mating system of a population of Myracrodruon urundeuva F.F. &amp;amp; M.F. Allemão using the fAFLP molecular marker
Provedor de dados: 74
Autores: Freitas,Miguel L.M.; Sebbenn,Alexandre M.; Moraes,Mario L.T.; Lemos,Eliana G.M.
The mating system and genetic diversity were studied in a natural population of Myracrodruon urundeuva originating from 30 open-pollinated trees at the Paulo de Faria Ecological Station, SP, Brazil. The progenies were planted on the Teaching and Research Farm of the Ilha Solteira Engineering School, UNESP. Using the fAFLP molecular marker, eleven loci were selected to study the mating system. The mating system was analyzed using the multilocus mixed-mating model. The estimates of genetic divergence between pollen and ovule allele frequencies were significant for eight loci, suggesting nonrandom outcrossing. The estimates of the multilocus outcrossing rate revealed that M. urundeuva possesses a mating system with a predominance of outcrossing events (theta...

The objectives of this work were to analyze seeds from 20 trees of aroeira (Myracrodruon urundeuva Fr. All.) of a natural population located in the region of Selvíria, State of Mato Grosso do Sul, Brazil, in order to evaluate their protein, lipid and carbohydrate contents, and to estimate their genetic variation. A completely randomized experimental design consisting of 20 treatments (families) was set up, with two replications. Four types of proteins were detected: albumin (35.0 to 107.3 mg/g seed), globulin (3.4 to 9.3 mg/g), prolamin (60.0 to 135.2 mg/g) and glutelin (118.0 to 286.0 mg/g). The lipid content varied between 200 and 334 mg/g seed. The total sugars also varied (26.5 to 46.3 mg/g seed), with a predominance of polyols (arabinitol, mannitol,...

Provedor de dados: 102
Autores: ANJOS,JOSÉ R. N.; CHARCHAR,MARIA J. A.; GUIMARÃES,DANIEL P.
O fungo Phomopsis sp. foi consistentemente isolado de plantas de aroeira (Myracrodruon urundeuva.) com sintomas de queima nas folhas, no Distrito Federal, em 1999. Testes de patogenicidade em casa de vegetação confirmaram Phomopsis sp. como o agente etiológico da doença. Dezesseis, de 20 outras espécies vegetais inoculadas em condições similares, também foram suscetíveis ao fungo.

ABSTRACT Myracrodruon urundeuva is a plant native to Brazil, which is used by the indigenous population for the treatment of candidiasis. The aims of this study were to evaluate the antifungal activity of extract against human vaginal Candida species and evaluate the possible toxicological activities of M. urundeuva. Initially, ethanol extracts, ethyl acetate fractions, and hydroalcoholic fractions of the bark and leaf of M. urundeuva were used to determine the minimum inhibitory concentration. The extracts that showed antifungal activity were characterized by liquid chromatography and subjected to toxicity assessment. Toxic, cytotoxic, genotoxic, and mutagenic testing were performed using Allium cepa and Ames assays with the ethanol extracts of the bark...

Study of the antiproliferative potential of seed extracts from Northeastern Brazilian plants
Provedor de dados: 42
Autores: Ferreira,Paulo Michel P.; Farias,Davi F.; Viana,Martônio P.; Souza,Terezinha M.; Vasconcelos,Ilka M.; Soares,Bruno M.; Pessoa,Cláudia; Costa-Lotufo,Letícia V.; Moraes,Manoel O.; Carvalho,Ana F.U.
This study assessed the antiproliferative and cytotoxic potential against tumor lines of ethanolic seed extracts of 21 plant species belonging to different families from Northeastern Brazil. In addition, some underlying mechanisms involved in this cytotoxicity were also investigated. Among the 21 extracts tested, the MTT assay after 72 h of incubation demonstrated that only the ethanolic extract obtained from Myracrodruon urundeuva seeds (EEMUS), which has steroids, alkaloids and phenols, showed in vitro cytotoxic activity against human cancer cells, being 2-fold more active on leukemia HL-60 line [IC50 value of 12.5 (9.5-16.7) μg/mL] than on glioblastoma SF-295 [IC50 of 25.1 (17.3-36.3) μg/mL] and Sarcoma 180 cells [IC50 of 38.1 (33.5-43.4) μg/mL]. After...

Provedor de dados: 52

ABSTRACT The aim of this study was to evaluate the effect of ethanolic "aroeira" (Myracrodruon urundeuva) extract on the viability of human gingival fibroblast. For this, fibroblasts (2x103 cells/well) were plated in a 96-well plate and incubated for 24 h; the medium (Eagle's medium modified by Dulbecco - DMEM) supplemented with 10% fetal bovine serum was replaced by DMEM with different ethanolic extract concentration (0, 0.1, 1, 10, 100, and 1000μg / mL). The fibroblast viability was analyzed after 48,72, and 96 h by the neutral red capture test and violet crystal. The "aroeira" extract, at high concentrations (100 and 1000 µg/mL) caused decrease in both cellular viability tests (p&lt;0.05). However, dilutions between 0.1 and 10 µg/mL did not affect the...

Atividade fotossintética e peroxidação de lipídios de membrana em plantas de aroeira-do-sertão sob estresse hídrico e após reidratação
Provedor de dados: 61
Autores: Queiroz,Cristina G. S.; Garcia,Queila S.; Lemos Filho,José Pires.
Avaliaram-se os efeitos do estresse hídrico e da reidratação sobre parâmetros de fluorescência, condutância estomática e peroxidação de lipídios em plantas de Myracrodruon urundeuva Fr. All. (Anacardiaceae). As plantas foram cultivadas em casa de vegetação e a seca foi induzida por suspensão da irrigação durante 14 dias. Sob estresse hídrico, observou-se queda acentuada no conteúdo relativo de água foliar, o qual alcançou valores próximos a 60 %. Essa queda foi acompanhada por grande diminuição na condutância estomática e na taxa aparente de transporte de elétrons (ETR) e extensivos danos às membranas evidenciados por aumentos na peroxidação de lipídios. Apesar do decréscimo nos valores de ETR, não se observaram alterações nos valores do rendimento...

O estudo objetivou realizar ensaio toxicológico pré-clínico inicial para investigar a toxicidade das folhas de alecrim-pimenta (Lippia sidoides Cham.), aroeira (Myracrodruon urundeuva Fr. All.) e barbatimão [Stryphnodendron adstringens (Mart.) Coville] e do farelo da casca de pequi (Caryocar brasiliense Camb.), por meio da determinação da dose letal 50% (DL50). Na investigação da DL50, foram utilizados grupos de camundongos Swiss de mesmo sexo (n=150, sendo 30 animais por tratamento) inoculados, por via intraperitoneal, com diluições seriadas do extrato hidroalcoólico das folhas de alecrim, aroeira e barbatimão e do farelo da casca de pequi. Após a inoculação, os animais foram observados por um período de 14 dias, para determinar a quantidade de mortos,...
