eng	Analysis of Essential Oils in Herbal Teas by means of Dispersive Liquid – Liquid Microextraction Method	This work deals with the optimization and the application of Dispersive Liquid-Liquid Microextraction (DLLME) and Dispersive Liquid-Liquid Microextraction Based on the Solidification of Floating Organic Drop (DLLME-SFO) microextraction methods for isolation of essentials oils in herbal teas. The optimizations of individual experimental conditions for both mentioned methods were performed with the use of orthogonal central composite design (CCD). Evaluation of optimal parameters was realised by the response surface modelling (RSM) approach where the desirability of individual parameters were tested. The optimized procedures were applied for the extraction of essential oils from real herbal tea samples. The analytical separation was performed with the usage of gas chromatography with the flame ionization detector. The results obtained by these methods were compared.
