Goniothalamin - A potent mosquito larvicide from Bryonopsis laciniosa L.

Abstract

Goniothalamin isolated from the indigenous plant, Bryonopsis laciniosa L., was highly effective against the larvae of the mosquito, Culex quinquefasciatus Say, as a mosquitocide. This is the first report of goniothalamin. The structure of the bioactive compound isolated from the EtOAc (CH3COOC2H5) fraction was established through spectroscopic methods using 1H-NMR and 13C-NMR in CDCl3. The mass spectrum was also recorded using VG micromass ZAB mass spectrometer.
