1. In vivo potential hypoglycemic and in vitro vasorelaxant effects of Cecropia glazioviistandardized extracts
ABSTRACTThe aim of this study is to investigate the effect of Cecropia glaziovii Snethl, Urticaceae, extracts on the oral glucose tolerance curve, on glycemia in alloxan-induced diabetic rats and vasorelaxant effect after the extraction process, and to standardize the extractive solutions. The effects of the process variables and their interactions were calc

2. Technological development of aqueous extracts from Calycophyllum spruceanum (Benth.) Hook. f. ex K. Schum., Rubiaceae, (mulateiro) using factorial design
The aim of the present work is to characterize the vegetal raw material of the Calycophyllum spruceanum (Benth.) Hook. f. ex K. Schum., Rubiaceae, known as "mulateiro", and to evaluate the influence of extractive parameters for attainment of standardized aqueous extractive solutions. The physical-chemical characterization of the samples was performed using p

3. Ion pair-dispersive liquid-liquid microextraction of trace amount of rhodium ion in water and road dust samples prior to flame atomic absorption spectrometry determination
A simple ion pair-dispersive liquid-liquid microextraction method was proposed for preconcentration trace amounts of rhodium. An ion association complex of RhCl4- and tetradecyldimetylbenzylamonium was extracted into cholorobenzene. The volume and the type of extractive and dispersive solvents, the extraction time and the pH of the aqueous solutions were opt

4. Desenvolvimento tecnológico de soluções extrativas aquosas de Phyllanthus niruri L. (quebra-pedra) empregando planejamento fatorial / Technological development of aqueous extracts from phyllanthus niruri l. by using of factorial design
Planejamento fatorial do tipo 32 foi realizado para avaliar a influência dos parâmetros: técnica de extração (infusão/decocção); proporção planta:solvente (2,5% e 7,5 %) e tempo de extração (5 e 15 minutos), sobre o teor de flavonóides encontrado em soluções extrativas aquosas de Phyllanthus niruri L. A solução que apresentou maior teor de f
