Dispersive liquid-liquid microextraction (DLLME) followed by gas chromatography-mass spectroscopy (GC-MS) was used to analyses of components of floral-water of Rosmarinus officinalis . Some effective parameters such as volume of extraction, disperser solvents and salt effect were studied by a full factorial design for obtain the optimum condition. The main compounds of the floral-water of Rosmarinus officinalis were a-pinene (16.7%), camphr (9.1%) and 1,8-cineole (8.5%).
