Cunha, Gracielle Oliveira Sabbag; Terezan, Ana Paula; Matos, Andreia Pereira; Burger, Marcela Carmen de Melo; Vieira, Paulo CezarThis study evaluated the antimicrobial activity of isolated compounds and semisynthetic derivatives from Miconia ferruginata (Melastomataceae) against five microorganisms: Staphylococcus aureus (ATCC 25923), Escherichia coli (ATCC 25922), Bacillus subtilis (ATCC 6623), Pseudomonas aeruginosa (ATCC 15442), and Candida albicans (ATCC 10231). The isomeric mixture of ursolic and oleanolic acids was active against S...

New Limonoids from Dictyoloma vandellianum and Sohnreyia excelsa: Chemosystemat...
Sartor, Claudenice F.P.; Lima, Maria da Paz; Silva, Maria M.G.F. da; Fernandes, João Batista; Forim, Moacir Rossi; Pirani, José RubensMolecular phylogenetic studies separated and united a group of genera that constituted the Spathelia-Ptaeroxylon clade, in which Dictyoloma and Sohnreyia have been included. Our taxonomic interest in the Dictyoloma vandellianum and Sohnreyia excelsa stimulated an investigation of both species searching for limonoids. Leaves from D. vandellianum afforded the new limonoid 1,2-dihydro-1α-hydroxy-8,30-epoxy-cneorin...

Carlos, Amanda Aparecida [UNESP]; da Silva Malaquias, Karla; Consolmagno, Rafael Camargo [UNESP]; Sarria, André Lucio FranceschiniMade available in DSpace on 2018-12-11T17:15:55Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-06-01; Leaf-cutter ant plant material choice is essential for colony maintenance and growth. Plant material is used as a substrate for cultivating symbiotic fungus, and the ants’ preference for particular leaves, tends to be determined by vegetal age-related physicochemical factors. The plant species Virola se...
Compatibility of polymers to fungi Beauveria bassiana and Metarhizium anisoplia...
Wenzel Rodrigues, Inajá Marchizeli; Batista Filho, Antonio; Giordano, Isabella Barichello; Denadae, Bárbara Evelin; Fernandes, João BatistaStability during storage is a limiting factor in the development and use of bioinsecticides. This study aims to evaluate the compatibility of the entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana with components used in encapsulated formulations and to evaluate shelf-life in formulations with B. bassiana. Sodium alginate and maltodextrin, hemicellulose, and dimethyl sulfoxide solvents were ev...
Atividade inseticida de óleos essenciais de Pelargonium graveolens l'Herit e Li...
Niculau, Edenilson dos Santos; Alves, Péricles Barreto; Nogueira, Paulo Cesar de Lima; Moraes, Valéria Regina de Souza; Matos, Andreia PereiraInsecticidal activity of essential oils of Pelargonium graveolens, Lippia alba and compounds geraniol, linalool, 1,8-cineole, limonene, carvone, citral and Azamax® were evaluated against Spodoptera frugiperda. Topical application assay showed essential oil of P. graveolens has acute toxicity against Spodoptera frugiperda larvae (third instar) with LD50 1.13 µg/mg per insect and LD90 2.56 µg/mg per insect.
