Abstract
This research paper proposes an analytical methodology for identifying fatty acids in pottery samples from various mining settlements with the aim of identifying their possible content and use. The analytical procedure comprised several steps: 1) a range between 1-2g of sample were weighted and placed in an ultrasound vessel; 2) 15mL of extraction a mixture dichloromethane and methanol (2:1 v/v) were added in the vessel; 3) lipids and fatty acids, in addition to other compounds, were extracted in a ultrasonic bath (Mod 5133 JP Selecta, Barcelona, Spain) during 15 minutes (two times); 4) in order to obtain a clean extract, the extracts were centrifugated at 3500 rpm during 5 minutes; 5) the two extracted liquids were collected and dry until dryness using nitrogen and heat (50-60 0C); and 6) 500μL of Toluene and 37,5μL of Meth-Prep II were added to carry out the derivatization reaction. The procedure required 30 minutes at ambient temperature in the ultrasonic bath. 7) Finally, the derivatized samples were injected in the chromatograph (1μL) or into the High Resolution Mass Spectrometer (100 μL). The archaeological sites included in the study were El Puig Roig del Roget (10th-6th c. BC) and Sant Miquel in Vinebre (2nd-1st c. BC), all linked to the Priorat mining basin in Tarragona province, and Otero de Herreros (1st c.) in Segovia.
