Abstract

Background and Aim: Single drop micro-extraction (SDME, solvent phase micro-extraction, liquid–liquid micro extraction, etc.) is less well-known and is based on a traditional liquid–liquid extraction (LLE) technique, but utilizes only a few microliters of organic solvent as the extracting phase. Materials and Methods: A gas chromatography–mass spectrometry (GC–MS) based approach has been proposed in the present study in order to specify the essential oil constituents in Grammosciadium platycarpum Boiss. This method was developed following the microwave assisted headspace single-drop micro-extraction (MH-SDME). Results: The optimization was carried out for the MH-SDME parameters that included the microwave power, the sample weight, the nature of the extracting solvent, the extraction time, as well as the volume of the microdrop. Conclusion: Functioning of the approach proposed here was compared with the traditional hydrodistillation (HD) and single-drop micro-extraction (SDME). In order to identify the volatile compounds in G. platycarpum, the MH -SDME and HD -SDME methods were successfully used in this study. The use of these methods led to the identification of 31 compounds in G. platycarpum. In comparison with HD and HD -SDME approaches, MHHS-SDME is a basic, quick and economical approach for analyzing the essential oils in G. platycarpum.
