Abstract

Chromatographic analysis of air-dried berries of Embelia schimperi led to the isolation of methyl vilangin (1), which was characterized on the basis of physical and spectroscopic data. The compound was found to be lethal against 2^nd instar larvae of Aedes aegypti (yellow fever vector) by first stopping the process of metamorphosis from the 2^nd instar stage to the other stages and finally causing mortality to the larvae.
