"Four nickel-based catalysts are synthesized by wet impregnation and evaluated for the hydrotreatment/hydrodeoxygenation of beech wood fast-pyrolysis bio-oil. Parameters such as elemental analysis, pH value, and water c...

The presence of rice bran or soybean oil at different concentrations (3 and 5 %) in gel-creams containing benzophenone-3 (BZ-3) was evaluated. Gel-creams were prepared with Carbopol Ultrez® (polymer) at 0.5 % (w/w). T...

In this work, fruits of three cultivars, Caingangue, Cherokee and Guarani, originated from collections from Embrapa, Pelotas, Rio Grande do Sul, were analyzed concerning the anthocyanin content and the essential oils com...

Several species of the Polygonum genera are collectively known in Brazil under the name "erva-de-bicho". In tradicional medicine, these species often mistaken for each other and are probably used for the same therapeutic...

Traditional usage of Schinus terebinthifolius Raddi, popularly known as Brazilian pepper, includes the treatment of inflammatory diseases. Chemical composition of the essential oil extracted of fruits of S. terebinthifol...

Los compuestos volátiles presentes en frutas de guabiju (Myrcianthes pungens), guabiroba (Campomanesia xanthocarpa), cereja-do-rio-grande (Eugenia involucrata), pitanga (Eugenia uniflora) y araçá (Psidium cattleyanum)...

"The thermochemical decomposition of beech wood biomass results in a poor quality bio-oil, which cannot be directly used in diesel engines. In order to make this oil resemble liquid fossil fuels, an upgrading technique s...

The objective of the present investigation was to develop and evaluate microemulsion-based hydrogel (MBH) for the topical delivery of sinomenium. The solubility of sinomenium in oils and surfactants was evaluated to iden...

In this study, the essential oil composition, total contents of phenolics and proanthocyanidins, antioxidant and antimicrobial activities from different plant parts (root, stem, leaf and fruit) of Campomanesia pubescens ...

Se determinó la composición química y la mutagenicidad de los aceites esenciales obtenidos de las hojas del Ocimum selloi Benth, perteneciente a la familia Lamiaceae, nativos de la región sur de Brasil. Para el estud...

Se estudiaron los aceites esenciales de cáscaras de frutos y hojas de mandarinas injertadas, cultivadas en Rio Grande do Sul (Brasil), para establecer la influencia del pie, comparándolas con la misma variedad crecie...

The objective of the work was to develop, optimize and evaluate self-microemulsifying drug delivery system (SMEDDS) of carvedilol (CDL), a poorly water-soluble drug. SMEDDS was developed to increase the solubility, disso...

Seasonal variation of the oil composition and biological activities from aerial parts of Achyrocline satureoides were investigated. Essential oils were analysed by gas crhromatography-mass spectrometry (GC-MS) after hydr...

The Hydrophilic-Lipophilic Balance (HLB)was formally presented by William C. Griffin sixty years ago at a meeting in Chicago for the first time and later on in an article published in the first volume of the Journal of t...
