Chemical characterization of Handroanthus vellosoi wood. Caracterização química da madeira de Handroanthus vellosoi. [PDF]

Revista do Instituto Florestal, 2012
The main chemical components of wood are cellulose, hemicellulose, lignin and extractives. Knowledge of these components content enables to understand how the wood will behave as a raw material in its many uses.

From fertilizer to insecticide: urban leaf litter chemistry alters the survival landscape of Aedes aegypti. [PDF]

Pest Manag Sci
Chemical profiling and bioassays reveal that leaf‐litter leachates from urban trees flip between nourishing and killing Aedes aegypti larvae: dilute Tipuana tipu boosts growth, whereas concentrated, aged extracts are >90% lethal. Species‐specific chemistry thus turns street trees into potential self‐renewing tools for integrated vector control ...

Larvicidal Activity of Phytochemicals From Handroanthus impetiginosus Seeds Against Culex quinquefasciatus. [PDF]

Chem Biodivers
The hexane extract was obtained from the seeds of H. impetiginosus, from which fatty acids and FAMEs were obtained. The three samples were tested on C. quinquefasciatus larvae, promoting mortality with moderate LC50 values. The hexane extract was analyzed by gas chromatographymass spectrometry (GC‐MS), and the most abundant compounds were ethyl oleate (
