Efeito de íons metálicos sobre a viscosidade intrínseca e sobre a degradação té...
Oliveira, Francisco Carlos deThe examination of the effect of metallic ions over the intrinsic viscosity and thermic degradation of maniçoba's (Manihot glaziovii) natural rubber (NR) has been the main aim of this work. The inclusion of the metallic ions to the NR was carried out by mixing-up aqueous solutions of the metallic chlorides with chloroformic solution of the NR. The metal slender films of NR were prepared by evaporation of the so...
Estudo químico de fungos endofíticos associados a plantas do bioma caatinga.
Oliveira, Francisco Carlos deThe chemical study of endophytic fungi associated with plants of the Caatinga biome was carried out through the identification of volatile organic compounds (VOCs) and the isolation of non-volatile metabolites produced by ten fungi of the family Botryosphaeriaceae and one of the family Nectriaceae. In the identification of VOCs produced by the fungus Albonectria rigidiuscula (Nectriaceae), four different cultur...
Estudo de investigação química da espécie Lippia rigida Schauer (Verbenaceae).
Oliveira, Francisco Carlos deThis paper describes the study of chemical research of the species Lippia rigida Schauer (Verbenaceae), collected in the municipality of Muncugê, Bahia. Chromatographic analysis of the ethanol extract from leaves of L. rigid allowed the isolation and characterization of flavonoid-type flavanones 3 sakuranetin, pinocembrin and naringenin 2 flavanonois 7-methyl aromadendrin and taxifolin, 1 flavone genkwanin, 3 f...
