%X A simple and rapid method was described for the determination of cypermethrin in Ginkgo biloba leaves by high performance liquid chromatography (HPLC) with UV detection. A mixture of hexane and acetone (99:1) was used to extract the samples. After the sample cleanup was carried out with a mixture of petroleum ether and ethyl acetate (9:1) cypermethrin in the sample was analyzed using a Phenomenex Luna 5 micron second-generation silica column packed with Florisil and active carbon. The recovery of cypermethrin was 81.0% and the relative standard deviation was 3.2%.
