ABSTRACT Cardanol is a constituent of Cashew Nut Shell Liquid that presents larvicidal activity against Aedes aegypti. The isolation of cardanol is somewhat troublesome, however, in this work we describe an efficient and inexpensive method to obtain it as a pure material. The compound was used as startin...

ABSTRACT The present study investigated the antioxidant effect of a new class of quinoline derivatives (a-d) on assays in vitro. Lipid peroxidation, thiol peroxidase-like and free radical scavenging activities were determined to evaluate antioxidant activity of compounds. Thiol oxidase-like and δ-am...

ABSTRACT Mori folium, the leaf of Morus alba L. (Moraceae), has been traditionally used for various medicinal purposes from ancient times to the present. In this study, we examined the effects of water extract of Mori folium (WEMF) on the production of inflammatory mediators, such as nitric oxide (NO) an...

ABSTRACT Enzymatically crossliked gelatin hydrogel was submitted to two different drying methods: air drying and freeze drying. The resulting polymeric tridimensional arrangement (compact or porous, respectively) led to different thermal and swelling properties. Significant differences (p < 0.05) on t...

Esse estudo teve por objetivo avaliar o potencial de transmissibilidade ultrassônica de um gel fitoterápico de copaíba da espécie Copaifera duckei Dwyer na concentração de 10%. A pesquisa foi registrada junto ao Sistema Brasileiro de Biodiversidade. O gel fitoterápico de Copaifera duckei 10% foi m...
Background: β-Galactosidases catalyze both hydrolytic and transgalactosylation reactions and therefore have many applications in food, medical, and biotechnological fields. Aspergillus niger has been a main source of β-galactosidase, but the properties of this enzyme are incompletely studied. Results: ...
Resumo Este estudo objetiva descrever a utilização e a disponibilidade de medicamentos fitoterápicos e plantas medicinais nas unidades de atenção básica do estado de São Paulo, a partir dos resultados do primeiro Ciclo do Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica ...
Background: Jatropha curcas is a wide-spreading latex-rich biodiesel plant with high oil content in seeds that have always been under intense studies. However, studies are lacking on the latex component that is considered rich in proteins with potentially important physiological functions and secondary m...
