1. THE PHENOLIC COMPOSITION OF THE HEPATOPROTECTIVE AND ANTIOXIDANT FRACTIONS OF Albizia lebbeck L.
An investigation of the hepatoprotective and antioxidant activities of the chloroform, ethyl acetate and n-butanol fractions of the leaves of Albizia lebbeck L. was performed. The first two fractions expressed the best results regarding the suppression of the increased levels of plasma amino-transferases and alkaline phosphatase in liver-damaged mice (after

2. Efeito da ração hiperlipídica e do extrato aquoso de erva-mate (Ilex paraguariensis) sobre a composição corporal e sobre a resposta inflamatória de macrófagos peritoniais de ratos Wistar / Effect of high-fat diet and yerba mate aqueous extract (Ilex paraguariensis) on body composition and on inflammatory response of peritonial macrophages in Wistar rats
Introduction Inflammation is involved in the pathogenesis of metabolic syndrome and non communicable chronic diseases (NCCD). In macrophages, the nuclear transcription factor kappa B (NF-B) controls the gene expression of many inflammatory mediators and its activity can be regulated by several food bioactive compounds. Yerba mate (Ilex paraguariensis) contai

3. Nitrogen and potassium effect on the interaction between Coccus viridis and Coffea arabica / Efeito de nitrogênio e de potássio na interação entre Coccus viridis e Coffea arabica
A cochonilha verde Coccus viridis (Green) (Hemiptera: Coccidae) causa problemas em plantas jovens de Coffea arabica e em partes do dossel com baixa luminosidade. A adubação das plantas com nutrientes como o nitrogênio e o potássio pode influenciar a sobrevivência, o desenvolvimento, o crescimento, a reprodução e o comportamento dos insetos. O impacto

4. Simultaneous determination of cafeic and chlorogenic acids by fluorescence / Desenvolvimento simultanea dos acidos cafeico e clorogenico por fluorencencia
The present work concerns the application of molecular fluorescence and multivariate calibration method, in the PLS-1 modality, for the simultaneous determination of caffeic (CA) and chlorogenic (CGA) acids in synthetic samples and in real samples of aqueous vegetable extracts of Ilex paraguariensis, using the intrinsic fluorescence of both compounds. The de

5. Constituintes químicos de Ottonia corcovadensis Miq. da floresta Amazônica: atribuição dos deslocamentos químicos dos átomos de hidrogênio e carbono
In an ethanolic extract of leaves of Ottonia corcovadensis (Piperaceae) were identified sixteen terpenoids of essential oil and the three flavonoids 3',4',5,5',7-pentamethoxyflavone (1), 3',4',5,7-tetramethoxyflavone (2) and 5-hydroxy-3',4',5',7-tetramethoxyflavone (3) and cafeic acid (4). Two amides (5 and 6) were isolated from an ethanolic extract of the r
