Abstract	A rapid and simple method for the determination of propionylbrassinolide residues in tomatoes, apples and grapes using GC–MS is reported. Samples were extracted with acetonitrile, and the extracts were analyzed without any further clean-up. The results showed good linearity (r 2 > 0.99) with standard solutions over the concentration range of 0.5–50 mg L−1. The LODs and LOQs of propionylbrassinolide were 0.15 and 0.5 mg kg−1 in all samples. Recoveries were in the range of 81.9–111.2%, with corresponding RSDs of 4.6–12.9% for three fortified levels. Intra- and inter-day RSDs were in the ranges of 1.5–14.2% and 5.3–15.6%. It was demonstrated that the proposed method is simple and efficient, and particularly suitable for detecting propionylbrassinolide residues in fruit and vegetables.
