Single-Drop Microextraction Using Two Fast Methods: Microwave and Heat for the Determination of the Volatile Compounds from Grammosciadium platycarpum Boiss and Hausskn

Keywords: Single-drop microextraction, Grammosciadium platycarpum Boiss, Headspace, Microwave


A gas chromatography–mass spectrometry (GC–MS) based approach is proposed in the current 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). The optimization was done 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 micro-drop. 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 carried out successfully in the current work. These methods identified 31 compounds in G. platycarpum. In comparison with HD and HD -SDME approaches, MH-HS-SDME is a basic, quick, and economical approach for analyzing the essential oils in G. platycarpum.
