## Abstract

This invention provides a method for repelling biting insects such as mosquitoes by topically applying to the skin of a subject fractions of emu oil obtained by flash chromatography. Also provided are methods for repelling biting insects by topically applying diluted fractions of emu oil. The invention also provides a compound useful in repelling biting insects having the NMR spectrum of FIG. 3, that is ultra violet light sensitive and is reactive to vanillin/sulfuric acid. Also provided are compounds useful in repelling biting insects having the NMR spectrum of FIG. 4, that is not ultra violet light sensitive and is not reactive to vanillin/sulfuric acid.

## Claims

### Claim 1

A method for repelling biting insects comprising the step of topically applying to the skin of a subject in need of repellence of biting insects a fraction of emu oil obtained by flash chromatography having the .sup.1 H NMR (300 MHz, CDCl.sub.3) spectrum of FIG. 4 and that is not ultra violet light active and non reactive with vanillin/sulfuric acid.

### Claim 2 (depends on 1)

The method of claim 1 wherein the emu oil fraction is diluted.
