Abstract

The methanol extract of fresh vegetative aerial parts of Spilanthes mauritiana afforded, after repeated chromatographic separations and mosquito larvicidal bioassays, a potent mosquito larvicide N-isobutyl-2E,4E,8E,10Z-dodeca-2,4,8,10-tetraenamide.The structure of the compound followed from spectroscopic considerations. It gave 100% mortality against third instar larvae of Aedes aegypti at 10-5 mg/ml. © 1986.
