Cambios bioquímicos en semillas de Lupinos montanus y Lupinus exaltatus asociados a tratamientos físicos, químicos y germinativos.
Provedor de dados: 32
Autores: Juárez Fuentes, Berenice.
Una alternativa para mejorar el valor nutricional de Lupinus silvestres es la aplicación de métodos tradicionales de procesado a las semillas. El presente estudio cuantificó los cambios bioquímicos en semillas de Lupinus exaltatus (Le) y L. montanus (Lm), especies silvestres mexicanas después de la aplicación de tratamientos físicos (hidrotérmico, remojo y descascarillado), químico (alcalino, Na2CO3 0.05%) y germinativo, para disminuir los compuestos anti-nutricionales (FAN’s) y mantener los nutricionales (CN). Muestras masales de semillas por especie fueron colectadas en 2012, en Chalchicomula de Sesma y Tlachichuca, Puebla. Los CN analizados antes y después de los tratamientos fueron: proteína cruda (PC), fibra cruda (FC), extracto etéreo (EE), cenizas...

A magyarországi máktermelésről
Provedor de dados: 31
Autores: Karacsony,   Peter; Toth,   Kalman; Pinek,   Gyula; Pal,   Robert.
Hazánkban az utóbbi években egyre nagyobb területeken folyik alkaloida és étkezési mák termelése. Megállapítható, hogy nem igazolódtak be azok a várakozások, melyek az uniós csatlakozástól a máktermelés csökkenését várták, annak ellenére, hogy az unió korlátozta egyes hazai, magasabb alkaloidatartalmú fajták termelését. Vizsgálataink alapján megállapítható, hogy a máktermelés magas hektáronkénti termelési költsége ellenére jövedelmező. Ha a hazai máktermelést az 1960-as évek szintjére emelnék, akkor az hozzájárulhatna a napjainkban fennmaradásukért és mindennapi megélhetésükért küzdő – elsősorban a szegényebb kelet-magyarországi régiókban – gazdálkodók megélhetéséhez.   ------------------------------------- The area used for growing poppy seed for human...

Production of caffeine alkaloid by Claviceps sorghi
Provedor de dados: 102
Autores: Bogo,Amauri; Mantle,Peter Gregory; Boff,Mari Inês C.; Amarante,Cassandro V. T. do.
The ergot disease of sorghum (Sorghum bicolor), caused by the fungus Claviceps sorghi, restricted to the Indian sub-continent, is a disease in which the pathogen infects the florets, colonizing the unfertilized ovaries. Losses are higher in hybrid seed production fields due to a higher susceptibility of male sterile lines. The sclerotia of C. sorghi have never been found to contain alkaloids with a tetracyclic ergoline ring system, which is normal in most ergot pathogens. In this work, we show that sclerotia of C. sorghi contain caffeine alkaloid and the ability to produce it in vitro.

Mururé (Brosimum acutifolium Huber) in the treatment of syphilis in colonial Amazonia: historical data to the actual contribution to treatment
Provedor de dados: 39
Autores: Vieira,Erika Fernanda de Matos; Lucas,Flávia Cristina Araújo; Campos,Maria da Graça Ribeiro; Germano,Carolina Mesquita.
ABSTRACT Historical ethnobotanical studies of medicinal plants reveal important information about traditional practices of human groups and influence current understanding of the use of plants. The present article describes the ethnopharmacology of mururé (Brosimum acutifolium) since the XVIII century for the treatment of syphilis and correlates past and present therapeutic use. This information contributes to the appreciation of historical records in the contemporary use of natural products. The analysis of documental records is important for comparing information available overtime about the medicinal use and application of specific species. The present research was based on the analysis of a Jesuit work and other complementary documents. The medicinal...

Influence of environment on the leaf morpho-anatomy and histochemical of the ayahuasca leaf: Populations cultivated in extra-Amazonian regions
Provedor de dados: 3
Autores: Miranda, Ordilena Ferreira de; de Souza, Saulo Eduardo Xavier Franco; Milan, Rodrigo José; Bueno, Aline Borges; Almeida, Marcilio de.
Psychotria viridis Ruiz &amp;amp; Pav. (Rubiaceae) occurs naturally throughout the Amazon and it is traditionally used by indigenous communities, being incorporated into religious use in urban contexts over the last few decades. It is known and cultivated in many regions of South America for possessing valuable bioactive alkaloids. In this paper, we described P. viridis leaf morphology, anatomy and histochemistry from three populations cultivated in the southeastern Brazil, in order to identify possible adaptations to local environment and management. All plants presented terminal stipules and basic morpho-anatomical patterns of leaves, consistent with most species of the genus, as heterogeneous dorsiventral mesophyll, uniseriate epidermis, presents large...

Screening of Metarhizium spp. strains for anticancer indolizidine alkaloid production and its rapid detection by MS analysis
Provedor de dados: 58
Autores: Justo,Oselys Rodriguez; Calheiros,Chrissana Santos; Perez,Victor Haber; Alegre,Ranulfo Monte.
Six fungi strains (M. anisopliae 3935, 4516, 4819, PL57, PL43 and M. flavoviride CG291) were studied regarding their ability to produce an anticancer indolizidine alkaloid. The culture process was carried out in Shaken flask at 26ºC and 200 rpm using three different culture medium containing oat meal extract supplemented with glucose and DL-lysine or Czapek culture medium. The mycelial extracts produced by Metarhizium spp. cultures were directly submitted to electrospray ionization mass spectrometry (ESI-MS) analysis and the highest alkaloid concentration (approximately, 6 mg.L-1) was reached when M. anisopliae 3935 was tested.
