Microwave Extraction of Essential Oils from Senecio serpens GD Rowly and Comparison with Conventional Hydro-Distillation Method

• Senecio serpens (family Asteraceae) is used as a medicinal plant in Portugal. The present study addressed the chemical profile of essential oils of S. serpens using microwave-assisted extraction (MAE) as a more efficient method for extraction compared to conventional hydro-distillation (HD) method. Gas chromatography-mass spectrometry (GC-MS) analysis of the essential oils identified a total of forty-seven components. According to the results, significant differences were observed in the constituents and percentages of the examined essential oils. Monoterpene hydrocarbons amounted for the major volatile constituents of the extracted oils, where it exhibited a content of 72.09% with MAE and 67.1% with HD. This is the first report of EO composition of the aerials parts of S. serpens. Microwave-assisted extraction presented several advantages as a green method for extraction with higher yield and reduced extraction time.
