A novel method based on the monolithic column solid-phase extraction (SPE) coupled with high performance liquid chromatography in online mode was developed for the determination of trace forchlorfenuron in fruits. The enrichment factor of SPE for forchlorfenuron was 214. The method was fully validated. It showed a linear range of 0.01-50.00 μg/L and a limit of detection of 25 ng/L, with the relative standard deviation (RSD) of 3.9%. The proposed method was successfully applied for the determination of forchlorfenuron in grape, kiwifruit and watermelon samples, with the recoveries of 87.0%-120.7% and the RSDs of 0.6%-9.2%. This online method was proved to be selective, sensitive and convenient for the determination of trace forchlorfenuron in complex samples.
