Application of Various SPME Methods in Analysis of Herbal Essential Oils
Department of Analytical Chemistry, Faculty of Chemical Technology, University of Pardubice, Pardubice
Headspace solid-phase microextraction (HS-SPME) and solid-phase microextraction coupled with hydrodistillation (HD-SPME) were used for detection and determination of essential oils in dried leaves of Mentha piperita L. , Lavandula augustifolia L. and Salvia officinalis L. The results were compared with those obtained using steam distillation, which is a reference method. The extraction time 15 min and the minimal fibre depth 1.4 cm are suitable for a 50/30 μm polydimethylsiloxane/divinylbenzene/carboxen fibre. The method was compared with HS-SPME and steam distillation.
