Abstract:

A method was developed for the determination of 9 pyrethroid pesticide residues in honeysuckle with solidphase
extraction and gas chromatography. The results showed that average recoveries of 9 pesticides spiked at 0.02, 0.1 and
0.5 μg/g were in the range of 82.8%–104.6% with relative standard deviation (RSD) of 3.5%–5.7%. The linear range of the
presented method was 0.01–0.8 mg/L, and the limits of detection (LOD) were 0.002–0.005 mg/L. The method is sensitive
and suitable for the analysis of pyrethroid pesticide residues in honeysuckle.

Key words: gas chromatography, solid-phase extraction, pyrethroid, pesticide residue, honeysuckle
