Larvicidal activity of 94 extracts from ten plant species of northeastern of Brazil against Aedes aegypti L. (Diptera: Culicidae)
Nineteen of the 94 extracts from six plant species showed significant activity against the fourth instar larvae and two of them, hexane and ethyl acetate extracts from stems of R. doniana and G. grazielae, were the most effective. Expand
Neutral components from hexane extracts of Croton sellowii
Qualitative analyses by GC–FID and GC–MS of the neutral fractions from hexane extract of the leaves, stems and roots of Croton sellowii were carried out. Sesquiterpenoids, n-alkanes, aliphatic estersExpand
Studies on the antimicrobial activity and brine shrimp toxicity of Zeyheria tuberculosa (Vell.) Bur. (Bignoniaceae) extracts and their main constituents
The results showed that extracts and isolated flavones from Z. tuberculosa may be particularly useful against two pathogenic microorganisms, S. aureus and C. albicans, and may justify the popular use this species since some fractions tested had antimicrobial activity and others showed significant toxic effects on brine shrimps.

Larvicidal activities and chemical composition of essential oils from Piper klotzschianum (Kunth) C. DC. (Piperaceae).
Both essential oil of P. klotzsdhianum and the isolate 1-butyl-3,4-methylenedioxybenzene are potential resources for A. aegypti larva control. Expand
Dilleniaceae family: an overview of its ethnomedicinal uses, biological and phytochemical profile
The ethnopharmacological uses, phytochemical profile and biological activities of some isolated compounds and extracts from Dilleniaceae species are reviewed for the first time. Expand
Bicyclo[3.2.1]Octanoid neolignans from Licaria brasiliensis☆
Abstract A hexane extract of the trunk wood of Licaria brasiliensis contained ten bicyclooctanoid neolignans, including six new representatives belonging to the 4-oxy-8-oxo-, 4-oxo-8-oxy- andExpand
Borreria and Spermacoce species (Rubiaceae): A review of their ethnomedicinal properties, chemical constituents, and biological activities
The ethnomedicinal uses, phytochemistry, and biological activities of some isolated compounds and extracts of some species of Borreira and Spermacoce, genera of Rubiaceae, are reviewed. Expand
Chemical Constituents and Preliminary Antimalarial Activity of Humiria balsamifera
From stems and leaves of Humiria balsamifera St. (Aubl.) Hill (Humiriaceae) were isolated 6 triterpenes [arjunolic acid, 2β,3α-dihydroxy-D:A-friedooleanane, friedelin, α- and β-amyrins and lupeol], aExpand
Modulation of Inflammatory Processes by Leaves Extract from Clusia nemorosa Both In Vitro and In Vivo Animal Models
Results indicate that C. nemorosa could be a good source for anti-inflammatory compounds and inhibited the chemoattraction of human neutrophils induced by formyl-methionyl-leucyl-phenylalanine, leukotriene B4 and platelet activating factor in a Boyden chamber. Expand
