In this work, extraction of volatile compounds (a-pinene, limonene, linalool, borneol, 2-phenylethanol, thymol and decanoic acid) in rose-water and fruit juices was followed using indirectly suspended droplet microextraction (ISDME). The ISDME is a combination of salting-out extraction of water-miscible organic solvents and directly suspended droplet microextraction (DSDME). A water-miscible organic solvent (2- propanol) was added to the sample solution. A homogeneous solution was formed immediately. A steady vortex was formed by agitation of the solution using a magnetic stirrer. By the addition of ammonium sulfate (saturated solution) to the homogeneous solution, 2-propanol was separated and collected at the bottom of the steady vortex. The effects of important parameters such as watermiscible organic solvents (type and volume), type of salt and extraction time were evaluated. Under optimized experimental conditions, the calibration graphs were linear in the range of 0.05–50.0 mg L1 with a coefficient of determination of more than 0.9992. Limits of detection and quantification values were in the range of 19–23 mg L1 and 63–77 mg L1, respectively.
