Resumo: Fractionation of Piper nigrum ethanol extract, biomonitored by assays on pyretbroid-resistant Aedes aegypti larvae yielded isolation of the larvicidal amides piperolein-A and piperine. Comparing LC50 values, the etbanol extract (0.98ppm) was the most toxic followed by piperoleinA (1.46ppm) andpiperine (1.531ppm).
